Safety notices
Be sure to pay attention!
In order to enjoy your modelling hobby for a long time, please read these instructions thoroughly and give particular attention to the safety notices.
If you are a beginner with remote controlled model aircraft, ships or cars, you should really ask an expe­rienced model pilot for assistance.
INTENDED USE
ATTENTION:
This remote control system may only be used for the purpose intended by the
manufacturer, i.e. for the operation of unmanned remote controlled models. Any other usage is not permissible and can cause damages to the remote control system, to other things and/ or to the people. For damages derived from other use we offer no warranty and take no liability.
ATTENTION:
NOT SUITABLE FOR KIDS UNDER 14
YEARS OLD, SAFETY IS NO ACCIDENT
and REMOTE CONTROLLED MODELS ARE NOT TOYS
… because even small models can cause substantial property damage and/or personal injuries if they are not handled properly - even if caused by third parties.
This manual is an important part of the set, it
contains important information for a proper
and safe use and maintenance. If this remote control system changes ownership, these instructions should surely be included with remote control system.
Failure to comply with the operating instruc-
tions and the safety instructions will void the
warranty.
Other notes and warnings
Technical defects of an electrical or mechanical na­ture can lead to unexpected startup of a motor and/or parts being hurled through the air to pose a danger of injury to you and to others.
Short circuit conditions are to be avoided absolutely! A short circuit condition may not only destroy parts of the remote control system but, depending on the circumstances and the battery energy involved, may also pose acute danger of incineration or even explo­sion.
All motor-driven parts, such as aircraft or ship propel­lers, helicopter rotors, open gearboxes etc. represent a constant danger. Contact with these parts must be avoided. A rapidly turning aircraft propeller can, for example, sever a finger. Also pay attention that other objects do not come into contact with driven parts.
When a drive battery is connected or a motor is running: never get into the danger zone of driving mechanisms.
Be sure to pay attention that motors do not start up unintentionally while performing programming opera­tions. Disconnect the fuel supply or battery terminals to motors before programming.
Protect all units from dust, dirt, moisture and other foreign parts. Never expose these units to vibrations or excessive hot or cold temperatures. Remote con­trol operation may only be performed under “normal” outdoor temperatures, i.e. within a range of -10 °C to +55 °C.
Avoid mechanical jarring and pressure stresses. Al­ways check units for damage to housings and cables. Do not use units which have been damaged or be­come wet, even after they are dry again.
Only those components and accessories which we recommend may be used. Always use original Graup- ner plug and jack connectors which are made for one another out of the same materials.
When routing cables, pay attention that they are not stressed, unduly kinked or broken. The sharp edges of adjacent parts also represent a hazard for insu­lated conductors.
Be sure that all plug and jack connections are firmly seated. Do not pull on the cable to disconnect a plugged connector.
No modifications whatsoever may be made to units. Modifications will void the operating permit and all insurance protection. If necessary, send the device concerned to your local Graupner Service Centre; see page 343.
Installing the receiver
The receiver is to be installed with a cushion of foam rubber to afford protection against
jarring; in aircraft models behind a strong rib, for a car or ship model the location must be protected against dust and spray water. However, do not en­close your receiver completely, otherwise it may overheat in use.
The receiver may not be mounted in direct contact with the hull or chassis as this would allow motor vibrations and/or roadway jarring to be transferred directly to the receiver. When a receiver system is installed in a model with a combustion motor, all receiver parts should always be protected against the intrusion of exhaust gases and oil residue. Above all, this applies to the model’s ON/OFF switch, which is typically built into the model’s outer surface.
Position the receiver such that connecting cables to the servos and the power supply are routed with a bit of slack and that the receiver’s antennas are at least 5 cm away from any large metal parts or wiring except for other receiver wires/cables. In addition to steel, this also includes carbon fiber parts, servos, electric motors, fuel pumps and all sorts of cables, etc.
Optimally the receiver should be placed at a readily accessible location that is well away from all other
Safety notices

equipment. Under no circumstances may a servo cable be wrapped around the antenna or routed close to it.
Make sure that cables near the antenna cannot move about during flight.
Routing the receiver’s antennas
The receiver and its antennas must be positioned as far away as possible from drives of any kind. If the model’s hull is made of carbon fiber material, the ends of the antennas must extend outside of the hull.
If your model features a carbon fibre fuselage, the aerial tips must always extend outside the fuselage for a length of at least 35 mm. If this is not possi­ble, it is essential to substitute longer aerials for the standard ones (approx. 145 mm long) fitted to HoTT receiver(s).
The orientation of the aerial(s) is not critical, but it is advantageous to install one receiver aerial in a vertical – upright – position in the model. If your receiver is a Diversity type – two aerials – the active tip of the second aerial should be positioned at 90 ° to the tip of the first aerial, and ideally the distance between the two tips should be greater than 125 mm.
Servo installation
Always mount servos with the provided rubber vibra­tion-damper parts, see “installation notes” on page
54. Only in this manner can these parts be pro­tected against excessively hard vibrations.
Installing control rods
Control rods must be installed such that they operate freely and smoothly. It is particularly important that all rudder levers are able to move to their full limits, i.e. not otherwise mechanically blocked.
In order to be able to stop a running motor at any time, control rods must be adjusted such that the carburettor tap is completely closed when the joystick and trim lever are brought into their end idle position.
Pay attention that no metal parts, e. g. as a result of rudder actuation, vibration, rotating parts, etc., rub against one another. Metal-to-metal contact causes electrical “noise” which can interfere with the correct operation of the receiver.
Transmitter antenna orientation
Transmission field strength is minimal in an imaginary line extending straight out from the end of the trans­mitter’s antenna. This means that “pointing” the trans­mitter’s antenna directly toward the model will not produce good reception but rather degrade reception.
When multiple remote controls are operating simulta­neously, pilots should position themselves in a loose group. Pilots standing off to themselves not only en­danger their own models but those of others as well.
However, when 2 or more pilots using 2.4 GHz remote control systems are closer than 5 m to one another this can lead to return channel overdrive which, in turn, will trigger a range warning much too early. Increase your distance between one another until the range warning ceases.
Pre-start checks Before switching the receiver on, be sure the throttle
control is at its Stop/Idle position.
Always switch the transmitter on rst
and then the receiver.
Always switch the receiver off rst
and then the transmitter.
If this sequence is not maintained, such that the receiver is still switched on when the corresponding transmitter is switched to “OFF”, then the receiver may respond to other transmitters or general radio frequency noise. This can cause the model to execute uncontrolled operations that may cause personal injuries and/or property damage.
In particular, for models equipped with a mechanical gyro:
before switching off the receiver, disconnect the model’s power supply to prevent the motor from rev­ving up unintentionally.
The residual spin of a gyro often produces so much voltage that the receiver may falsely interpret a throttle signal! This will then cause the motor to start up unexpect­edly.
WARNING:
If this order is not respected, that the receiver is turned on, but the corresponding transmit-
ter is “OFF”, the receiver could respond by other transmitters and any interference. The model can be run as a result uncontrolled steer­ing movements, thus possibly causing property dam­age and / or personal injury. In particular with a mechanical gyro for models: Before you switch your receiver off, make sure by interrupting the power supply, that the motor can not run up unintentionally.
An expiring gyro can generate such a voltage that the receiver picks up as an apparently valid throt­tle command. Then, the motor may start uninten­tionally!
Range test and function test
Perform checks for proper operation and
range before every session. Secure the mod-
el adequately in place and ensure that no one is in front of the model.
Perform a complete functional test on the ground and execute a complete simulated flight to exclude the possibility of system faults or problems with the mod­el’s programming. When doing this, be sure to follow the notices provided on pages 88 and 99.
Never operate the transmitter in Model mode, i.e. for flying or driving, without an antenna. Be sure the antenna is firmly seated in its socket.

Safety notices
WARNING:
If the range and functional test, and ight
simulation are not carried out in detail and
conscientiously, this may have undetect­ed malfunction and / or reception failures result in eg loss of control or even a crash of the model and can lead to signicant things and / or person­al injury as a result.
Operating a winged aircraft, helicopter, ship or car
WARNING:
high-voltage wires. Do not operate the model in the vicinity of sluice locks or where real boats or ships are operating. Do not operate a model on public streets or highways, paths or plazas, etc.
Never switch the transmitter off whilst operat-
ing a model! If this should happen acciden­tally, keep your nerve and wait until the trans­mitter screen is entirely blank, i. e. until the transmitter has shut down completely; this takes at least three seconds. Do not switch your transmitter on again until this has oc­curred. If you neglect this, there is a risk that the transmitter will “hang” immediately after being switched on, and you will lose control of the model. In this case your only recourse is to switch the transmitter off again, allow it to shut down completely, and then switch on once more after the correct interval.
Never y over spectators or other
pilots. Never endanger humans or
animals. Never y in the vicinity of
Aero-towing
WARNING:
When operating a powered tug, ensure that the receiving systems in the two
models are always at least 50 cm apart. We recommend the use of satellite receivers in such situations. If you neglect this, there is a chance of interference from the downlink channel.
Monitoring transmitter and receiver batteries
You must stop running the model to recharge
the transmitter’s battery no later than when
low transmitter battery voltage triggers the “Batt must be recharged!!” display and acoustic signal.
Check the charge in batteries routinely, particularly the receiver’s battery. Do not wait until the movements of controlled mechanisms are noticeably slower. Replace expended batteries before they cause prob­lems.
The battery manufacturer’s charging instructions are always to be followed, this includes mandatory ad­herence to the length of charging time. Never leave batteries being charged unattended.
Never attempt to charge primary batteries (non-re­chargeable batteries) because they can explode.
All secondary batteries (rechargeable batteries) must be charged before every session. To avoid short circuit conditions, first connect the charger cable’s banana plugs, polarity correct, into the charger and thereafter connect the charger cable’s plugs to the transmitter and receiver batteries.
Disconnect all power sources from the model when it is not to be used for an extended period of time.
Never attempt to use defective batteries, damaged batteries or mixed-type battery combinations as a sin­gle group. Do not use mixed combinations of old and new batteries or batteries of different manufacture.
Capacity and operating time
The rule: “capacity is reduced with every successive recharging”, applies to all batteries. Internal resist­ance increases at low temperatures to further reduce capacity. As a consequence, the battery’s ability to provide current and hold its voltage is reduced.
Frequent charging or the use of battery maintenance programs can also result in gradual loss of battery capacity. Therefore the capacity of batteries should be checked at regular intervals, not in excess of every six months, and replaced if performance is found to be significantly deficient.
Purchase only genuine Graupner batteries!
Interference suppression for electric motors
All conventional electric motors produce sparks between their collector and brushes.
Depending on the type of motor involved, this may cause more or less interference with the func­tionality of the remote control system.
The electric motors of a properly built system should therefore have interference suppression features. For electric drive models it is particularly important that every one of its motors is provided with proper inter­ference suppression. Interference filters extensively suppress such disturbances and should always be included.
Follow the respective recommendations included in the motor’s operating and installation notices.
For further details about interference filters, refer to the Graupner RC main catalog or in Internet at www.graupner.de.
Servo interference lters for extension cables
No. 1040 The servo interference filter is necessary when an
extended-length servo cable is used. This filter is at­tached directly to the receiver output. In critical cases a second filter can be attached to the servo.

Using electronic speed controllers
Choosing the right electronic controller is largely a matter of matching controller performance to the mo­tor to be controlled.
In order to prevent an overload or damage to the speed controller, its current rating should be at least half of the maximum locked-rotor current draw of the motor to which it is connected.
Particular attention is appropriate for so-called “tuning motors”. Because of their low-turns coils these motors can draw a multiple of their rated current in a locked­rotor condition and this can lead to the destruction of the speed controller.
Electric ignition systems
Combustion motor ignition systems also produce interference that can negatively influence remote control functionality.
Always supply power to an electric ignition system from a separate, dedicated battery.
Use only interference-suppressed spark plugs, spark caps and shielded ignition leads.
Mount the receiver sufficiently far away from ignition system components.
Static charges
WARNING:
A remote control system will be destroyed by the magnetic shock waves produced by a lightning strike – even if the storm is
miles away. Therefore, stop ying right away if a storm is approaching. Static charging via the antenna also represents a lethal hazard.
Attention
between this system’s antenna and other persons
In order to fulfill FCC HF emission require­ments for mobile transmitters, a distance of at least 20 cm must be maintained
when this system is operating. Operation of this system at a lesser distance is therefore not recom­mended.
• To avoid disturbance caused by the electrical characteristics and emissions of other transmit­ters, keep at least a 20 cm distance from other transmitters.
• Operation of the remote control system requires a correct program setting for the given country in the transmitter unit. This is necessary for compliance with diverse regulations like FCC, ETSI, CE etc. Follow the respective instructions provided for this with the transmitter and receiver.
• Prior to every flight, perform a complete functional test, range test and execute a complete simulated flight in order to exclude the possibility of system faults or problems with the model’s programming.
• Never program the transmitter or receiver while the model is being operated.
Care and maintenance
Never clean the housing, antenna, etc. with cleaning agents, gasoline, water or similar
P
means. Use only a dry, soft cloth.

Safety notices and handling regulations for Lithium-Ion (LiIo) and Lithium-Polymer (LiPo) batteries
As applicable for all highly technical products, obser­vance of the following safety notices and handling in­structions is essential for a long service life, fault-free operation, and harmless utilization of lithium/polymer batteries.
These instructions are to be safeguarded. If the unit is transferred to another user, these instructions should certainly be passed along to the new user.
LiIo-/LiPo batteries require particularly attentive han­dling. This applies to charging, discharging as well as for storage and other handling. Adherence to the following special specifications is necessary:
Special notices for charging LiIo-/LiPo batteries from Graupner
WARNING:
of improper charging or discharging.
• Only approved chargers with appropriate charging cables may be used for charging LiIo-/LiPo bat­teries. Any manipulation to the charger or charger cables can lead to severe damage.
• The maximum charging capacity must be limited to 1.05 times the battery’s capacity.
Example: 700 mAh battery = 735 mAh max. charging capacity
• Use only the outlet-charger included with the set or a specially designed charger/discharger from Graupner to charge and discharge LiIo-/LiPo bat­teries, refer to page 18 or www.graupner.de.
Since Graupner GmbH cannot supervise the correct charging and discharging of cells, the entire guarantee is void in cases
• Ensure the settings for the number of cells or for final charging voltage and final discharge volt­age are correct. Be sure to observe the operating instructions for your charger/discharger.
• Under these conditions Graupner LiIo-/LiPo bat­teries can be charged with a maximum of 2 C (the value 1 C corresponds to the cell capacity) charg­ing current. At a voltage of maximum 4.2 V per cell and above, charging must continue a constant voltage of 4.2 V per cell until charging current drops below 0.1 … 0.2 A.
• The permissible temperature range for charging and storing LiIo-/LiPo batteries is 0 … +50 °C.
• Never leave batteries being charged unattended.
• The battery to be charged must be placed on a non-combustible, heat resistant, non-conducting surface during the charging process. Combustible or readily ignited objects are to be kept away from the charging configuration. Batteries may only be charged under supervision.
• Avoid short circuit. Never pierce a LiIo/LiPo bat­tery, by doing it you may cause a short circuit and a fire, explosion and other problems.
• Charging voltage over 4.20 V per cell must be avoided absolutely as the cell would otherwise be permanently damage and could cause a fire. In or­der to prevent the over-charging of individual cells in a pack, a cut-off voltage between 4.1 … 4.15 V per cell should be set to increase service life.
• Incorrect handling can lead to explosions, fire, smoke and poisoning hazards. Furthermore, disregard for instructions and warnings can lead to performance losses and other defects.
• Before every use check the state of your batteries. Damaged or ruined batteries or cells should not be used.
• LiIo/LiPo batteries contain electrolytes and elec­trolyte vapours which are unhealthy. Never enter in touch directly with electrolytes. In case of contact with eyes, skin or other parts of the body, wash soon with a lot of water and call soon a doctor.
• The battery’s capacity is reduced by every charge/ discharge cycle. Storing the battery at tempera­tures which are too high or too low can also lead to a gradual reduction in capacity. In model opera­tion, battery capacity drops to about 50 … 80 % of new battery capacity after about 50 charge/dis­charge cycles – even though all charge/discharge rules are followed. This is due in part to the high discharge currents and inductive currents caused by motors.
• Never attempt to charge battery cells with the wrong polarity. Abnormal chemical reactions take place when batteries are charged with re­versed polarity and the battery will be useless.
This can cause breaks, smoke and ames.
• Battery packs may only be connected in series or parallel in exceptional cases as cell capacities and charged state can differ too greatly. This is why the battery packs we deliver are selected.
• LiIo-/LiPo batteries connected in series within a pack may only be charged as a group if the voltage of individual cells do not differ by more than 0.05 V. The LiIo battery included with the set is equipped with a special safety circuit such that “compensation” for voltage differences between individual cells, by way of an otherwise typical balancer plug connection, is not necessary.
• Individual battery cells and batteries are not toys and must therefore not get into the hands of chil­dren. Batteries/cells must be kept out of the reach of children.
Safety notices
8
• Batteries must not get into the vicinity of babies or small children. If a battery is swallowed, immedi­ately go to a doctor or emergency medical facility.
• Batteries must not be put in a microwave oven or put under pressure. Smoke, fire and more can be the consequences.
• Never dismantle a LiIo-/LiPo battery. Dismantling a battery can cause internal short-circuits. Gas, fire, explosions and other problems can result.
• The electrolyte and electrolytic vapors in LiIo-/LiPo batteries are harmful. Absolutely avoid all direct contact with electrolytes. If electrolytes come into contact with skin, eyes or other body parts, im­mediately wash out or rinse out with generous amounts of fresh water then be sure to consult a doctor.
• Batteries built into equipment must always be removed from that equipment when it is not cur­rently in use. Always switch off equipment after it is used to prevent deep discharging. Always charge batteries before it is too late. Store batteries on a non-combustible, heat resistant, non-conducting surface! Deep-discharged LiIo-/LiPo batteries are defective and may no longer be used!
Storage
LiIo-/LiPo cells should have a 10 … 20 % charge capacity when stored. If cell voltage
drops below 3 V, then LiIo-/LiPo cells must absolutely be recharged to a capacity of 10 … 20 % of full capacity. Otherwise, further deep-discharging of the battery will make it useless during storage in a discharged state.
Special notices for discharging LiIo-/LiPo batteries from Graupner

A continuous current rate of about 1 C does not represent a major problem for Graupner LiIo-/LiPo batteries. For larger
In any case, observe the maximum current rating for the connector system, see maximum discharge current on the battery.
• Discharging below 2.5 V per cell damages cells permanently and is therefore to be avoided abso­lutely.
Short circuit conditions are to be avoided absolutely. Permanent short circuits lead to destruction of the battery, high temperatures and perhaps even self-ignition may follow.
• During discharge, battery temperature must not rise, in any case, to over +70 °C. Otherwise, better cooling or a lower rate of discharge must be in­troduced. The temperature can easily be checked with the infrared thermometer, No. 1963. The bat­tery must never be discharged via the transmitter’s charging socket. This socket is not suitable for this purpose.

The Newest Generation of Remote Control Technology
The technical advances across the entire spectrum of model building is an ever-present challenge to design engineers. This is why the introduction of new trans­mission technology in the 2.4 GHz band represents a new milestone.
The HoTT-System (Hopping Telemetry Transmission) developed by Graupner is a synthesis of know-how, engineering and testing done around the world by professional pilots.
Established Graupner HoTT techniques theoreti­cally permit over 200 models to be operated at the same time. However, because of the interspersed radio-frequency utilization permitted by certifi cation for the 2.4 GHz ISM band, this number is signifi cantly lower in practical application. Nevertheless, in general more models can be operated simultaneously in the
2.4 GHz band than would be the case in conventional 35 or 40 MHz frequency bands. The real limiting fac­tor is – as often before – is still likely to be the size of available operating space (i. e. airspace for aircraft). Alone the fact that it is no longer necessary to coor­dinate transmitting frequencies with other pilots in the vicinity (which is sometimes quite diffi cult in broken landscapes, such as on hillside slopes) represents an enormous boost for remote control operating security.
Bidirectional communication between transmitter and receiver, by way of a return channel built into the receiver, permits convenient access to data and programming in the HoTT receiver. For example, this makes it possible to swap receiver outputs or to divide up control functions among multiple servos (channel mapping). Servo travel and servo rotation directions in the receiver can also be matched to one another with these facilities. Telemetry data, like VARIO and GPS data, can be called up from optionally available modules.
Based on the mc-24 Graupner/JR computerized remote control system, the control system has been especially developed for ex-

perienced RC pilots All conventional model types can be readily operated with the regardless of whether the model is a winged aircraft, helicopter, ship or land vehicle.
Complex mixed-control functions of guiding surfaces are often necessary for winged aircraft (rudder, eleva­tors) and helicopter models (swashplate). Thanks to modern computer technology, very diverse model requirements can be programmed in the simplest conceivable manner with touch-sensitive keys (CAP Touch). Simply select the given model type from the
mc- 3 2 HoTT system,
mc- 3 2 HoTT program and its software will assem-
ble all signifi cant mixer functions and coupling func­tions automatically. This eliminates the need for sepa­rate modules in the transmitter to implement complex coupled functions and also makes sophisticated mechanical mixer mechanisms in the model unnec­essary. For example, this makes the mc-3 2 HoTT transmitter fully equipped with both software and hardware to operate the well-known NAUTIC modules on the receiver side. The “channel sequencer” is new. It permits the operation of up to three servos to be automated.
mc- 3 2 HoTT system offers optimal security
The and reliability without having to forgo great operating convenience. The m c-32 HoTT remote control sys­tem has 80 model memory locations. Additional fl ight­phase-specifi c settings can be stored in every model memory location. For example, such settings can be made for various parameters that can be called up to implement particular fl ight maneuvers at the “press of a button”. Additional model memories can be stored on the SD card, which is included standard with the set. Even telemetry data can be recorded for subse­quent evaluation on a PC.
Since the plays, the lower display has been optimized for com­prehensible, simple operation of the software. The graphic representation of mixer functions is particu-

Functionally-related options are clearly arranged by content in a simple organization. The clear, compre­hensible program structure permits a beginner to quickly become familiar with the various functions and able to use all options pertinent to his level of exper­tise with remote control models.
This handbook describes every menu in detail. There are tips, many notices and programming examples to supplement the descriptions and also explanations for model specifi c technical terms, like transmitter con­trol, dual rate, butterfl y, and so on.
Please observe the safety notices and technical notices. Read through the instructions attentively. Before usage, test all functions by simply attaching servos to the receiver included in the set. While doing this, observe respective notes on page 68. This will help you learn the essential operating techniques and functions of the
Always handle your remote controlled model with a sense of responsibility so that you do not endanger yourself or others.

Opening the transmitter housing
Switch off the transmitter before opening it (power switch to »OFF«). Push both housing
base latches in the opposite the direction of the arrow marks, toward the inside, to their limits. Now tilt the transmitter somewhat to the rear so the housing base can fl ip open and can be unhooked. Close the transmitter's housing base by fi rst hooking it to the underside, fl ip the base closed then push both latches toward the outside. When closing the base, pay attention that no cables are pinched.
Notes:
• Be sure not to touch the circuit boards
with any metallic objects. Do not touch contacts with your fi ngers.
• Before performing any tasks inside the
transmitter, disconnect the transmitter's battery (see next page) to avoid potential short circuit damage to the transmitter's circuit boards.
Make no modifi cations of any kind to the circuit boards as this will void the guarantee as well as the unit's offi cial permit.

Charge the transmitter battery with the plug-in charger.
The transmitter's rechargeable LiIo battery can be charged by way of the charger socket located behind a cover on the left, front side of the transmitter – as viewed from the front – with the included plug-in charger (No. 32032.4).
Depending on the state of discharge, the included plug-in charger (4.2 V/500 mA) requires up to about 15 hours to fully recharge the transmitter battery.
Never use plug-in chargers from other manu­facturers or chargers intended for other bat-
tery types. Charger output voltage which is too high or possibly even different plug polarity, see further below, can cause immense damage. We recommend that this plug-in charger be appropriately labelled.
Also observe the safety notices provided on pages 4 … 7.
The transmitter must be switched "OFF"
during the entire charging procedure. Never
switch on the transmitter when it is connected to the charger. Even a brief interruption to charging can cause charging voltage to rise to a level that will immediately damage the transmitter with over-volt­age. Also for this reason, be sure all connectors are always plugged in securely and have good contact.

If the transmitter battery is charged with more than 1.5 A, it must be charged outside of the transmitter. Otherwise, the printed circuit board may be damaged from overloading the printed connectors and/or overheating the battery.
Perform a few test charges to make sure that the automatic cutoff of automatic chargers works. This is especially true when you want to use an automatic charger to charge the NiMH battery which comes standard in the mz-18 HoTT trans­mitter, or the lithium battery which comes stand­ard in the mz-24 HoTT transmitter. Monitor the cutoff behaviour if the charger that you are using has this option.
Do not discharge the battery or run battery care programs using the charging socket. The charg­ing socket is only for charging.
Always fi rst connect the charging cable to the charger, and then connect it to the receiver or transmitter battery. This prevents unintentional short-circuiting with the bare ends of the charging cable plug.
If the battery becomes hot, check the battery and exchange it or reduce the charging current.
• Do not charge the batteries without monitoring them.
• Follow the safety instructions and han­dling guidelines starting page
Follow the charging instructions of the charger manufacturer and battery manu­facturer.
Do not exceed the maximum permissible charging current of the battery manufac­turer. To prevent damage to the transmit-
Stick length adjustment
The length of both sticks can be continuously ad­justed to adapt these transmitter controls to the pilot's preference.
Hold the lower half of the knurled grip in place then turn the upper section to release its counter-locked threads.
Now pull up or push down on the stick's end to the desired length. When the length is suitable, tighten the counter-locked threads of the upper and lower sections again.

Neutralization
Both the left and the right stick can be confi gured for neutralized or non-neutralized operation. Open the transmitter.
To change the stick's factory setting, locate the screw shown in the fi gure below enclosed in a white circle.
Note:
The aggregate for the right stick is a mirror image of the left stick so the corresponding screw for the right stick is on the right side
just below the middle.
Now turn this screw down until the respective stick is free to move from limit to limit - or turn the screw out until the stick again completely self-restoring.
Brake spring and ratchet
The outboard screw of the two marked in the next fi gure adjusts the braking force and the inboard screw adjusts the strength of the ratchet for the respective stick.
Note:
The aggregate for the right stick is a mirror image of the left stick so corresponding screws for the right stick are located at the top left.
Stick restoring force
The stick's restoring force can also be adjusted to the pilot's preference. The adjustment is located next to the return springs, see markings in the fi gure below.
Spring force for the given direction of motion can be adjusted by turning the respective screw with a Phil­lips screwdriver.
clockwise = stronger return,
counter-clockwise = weaker return.

Installation of switches, switch modules and knob modules
There are a total of 20 holes in the transmitter's hous­ing available for mounting accessory modules.
ATTENTION:
To be safe, always disconnect the transmitter battery before installation to avoid short cir-
cuit conditions. Be sure to pay attention that soldered points on the transmitter board do not come into contact with metal objects!
Unoccupied holes in the transmitter's housing are closed with blind plugs. These can easily be pulled out from the outside with one's fi ngernails.
Insert the accessory switch, etc. through a hole in the housing from the inside.
Accessory switches, potentiometers, etc. are fastened into place by screwing a nut onto the threaded shaft protruding though the housing and tightening it with a suitable wrench. If the control has a knob, it can be reattached after the nut is tightened down. Trim nut wrench (No. 5733) is well suited for tightening down these nuts.
Aligning the antenna
The removable, articulated antenna is to be screwed into the ball-joint connector then aligned by hand.
The antenna exhibits very limited fi eld strength straight out from its end, pointing it directly toward the model is wrong.
ATTENTION:
When screwing in the antenna, pay attention that the centre pin in the antenna socket does not get bent or pressed back in the socket.

Face-side connections
Charger jack
The mc- 3 2 HoTT transmitter's charger jack be­comes accessible after turning the left face-side cover away.
The transmitter's rechargeable LiIo battery can be charged by way of the charger socket located behind a cover on the left, front side of the transmitter – as viewed from the front – with the included plug-in charger (No. 32032.4).
Maximum permissible charging current with Graupner automatic chargers: 1.5 A.
Never use plug-in chargers from other manufacturers or chargers intended for other battery types. Charger output voltage which is too high or possibly even different plug polarity, see further below, can cause immense damage.
More information about charging the transmitter's battery can be found on page 18. Observe the safety notices on pages 8 … 10 when handling lithium bat­teries.
DSC / Direct Servo Control
The acronym "DSC" is a carryover which stands for the original "Direct Servo Control" function. However, in HoTT systems the "direct servo control" function is no longer available via a diagnose cable due to tech­nical reasons.
Once the left face-side cover has been moved away,
mc- 3 2 HoTT transmitter's DSC socket is ac-
the cessible:
The standard two-pole DSC jack in the mc-32 HoTT transmitter is used as the teacher or pupil jack as well as an interface to fl ight simulators or external RF module.
To ensure a proper DSC connection, please observe:
1. Make any necessary menu changes. Refer to the section beginning on page 226 to
adapt the pupil system.
2. When operating a fl ight simulator or when operating the pupil transmitter, ALWAYS leave the transmitter's ON/OFF switch in the "OFF" position as only in this position does the transmitter's RF module remain inactive after the DSC cable is inserted. This also reduces the transmitter's power consumption somewhat.
Only the " constantly illuminated and the transmitter's basic display should show the character string "DSC" below the operating time clock. At this time, the

STICK CALIBRATION
If you feel the neutral position of your self-centreing sticks (controls 1 … 4) are not exactly 0 % of their control travel, then this can be checked and, if neces­sary, corrected as follows.
Jump to the »Model select« menu and initialize a free model memory as described on page 69. Wheth­er the model to be initialized is a winged aircraft or a helicopter is irrelevant.
Wait for the notices which typically appear in the transmitter's base screen following a model change then jump to the »Servo display« menu, for example by simultaneously touching the  keys of the left touch pad (WITHOUT any interim changes to trim settings or other program settings).
If all four of your transmitter's stick functions are still self-neutralizing, this display should ideally look like the one shown below.

For example, if the throttle/brake stick is in its "quarter-throttle" position, the display would appear as shown below.
… then the transmitter could not  nd a suitable  rmware  le on the inserted memory card. Check the contents of the SD card's "Firmware" directory on a PC or laptop.

Regardless of the number of self-neutralizing stick functions available on your transmitter, if these checks produce four 0 % results and eight 100 % results then your transmitter's sticks are optimally calibrated. You can terminate this process then, if appropriate, delete the model memory just created.
Otherwise jump (as described at the outset of the previous double page) to the "Stick calibration" line in the »SECRET MODE« menu...

Preliminary remarks about the mc-3 2 HoTT transmitter
Preliminary remarks
The Graupner HoTT system theoretically permits simultaneous operation of more than 200 models. However, because of the interspersed radio-frequen­cy utilization permitted by certifi cation for the 2.4 GHz ISM band, this number is signifi cantly lower in practi­cal application. Nevertheless, in general more models can be operated simultaneously in the 2.4 GHz band than would be the case in conventional 35 or 40 MHz frequency bands. The real limiting factor is – as often before – is still likely to be the size of available oper­ating space (i. e. airspace for aircraft). Alone the fact that it is no longer necessary to coordinate transmit­ting frequencies with other pilots in the vicinity (which is sometimes quite diffi cult in broken landscapes, such as on hillside slopes) represents an enormous boost for remote control operating security.
Battery charged?
Since the transmitter is delivered with an empty (not charged) battery, the battery must fi rst be charged according to the charging instructions on page 16. Otherwise a warning tone will be sounded and an appropriate message will be blended into the basic display if the low voltage threshold set in the "Battery warning" line of the »General basic settings« menu (see page 260) is underrun.
Transmitter startup
From fi rmware version V 1.090 “Motor on C1 forward / back” is after switching the transmitter when a surface model of the type analysed the position of the output to 1 or when the heli model is connected to the output 6 throttle servo.
Should the respective servo be outside the idling range thus can be a risk of a high-speed motor, for

You can now either wait until the display after a few seconds automatically disappears, or manually short­en the waiting time by tapping the centre SET key of the right touch pad.Within this brief period there is an opportunity to switch RF transmission off by using the or key of the right touch pad to shift the position of the fi eld shown in inverse video to the right so that ON is in standard video and OFF is presented in in­verse video.
Please select

Now switch the RF module off by tapping on the centre SET key of the right touch pad. The meantime glowing green “RF” LED to the right of the switch turns off. Then you are in the basic display of the transmitter and the front display the Graupner logo and type designation of the sender is displayed:

The symbol combination means that the currently active model memory has already "bounded " with a Graupner-HoTT receiver but there is no connection to that receiver at the moment. (In this example, RF trans­mission has been switched off.)
If, however, the transmitter is switched on without switching RF transmission off, the symbolic antenna mast will blink. At the same time, an acoustic warning will sound until a connection is established with the respective receiver. As soon as the connection is estab­lished, the "X" at the base of the symbolic antenna will be replace with a fi eld strength indicator, for example
, and the visual and acoustic warnings will cease.
If a telemetry connection has also been established for the incoming signal, that is output by the receiver in the model, then the right side of this same screen line will display a similar indication of signal strength for this reception of the receiver's transmitted signal (M ) as well as the current voltage of the receiver's power supply.
On the other hand, if the symbol combination appears in the display and the front display shows the message "Can't receive data" then the currently active model memory is not "bound" to any receiver at the moment.

Important notices:
2.4 GHz Set. The specific receiver included in the set has already been bound to the set's transmitter at the factory.
In order to achieve the greatest possible flexibility but still preclude unnecessary inadvertent operator errors, control channels 5 … 16 have not been assigned to any controls. This means that servos connected by way of these channels will remain in their middle positions until an operator element has been assigned. Practically all mixers are initially inactive for this same reason. More about this can be found on page 118 (winged aircraft) or 122 (helicopter models).
• The fundamental procedure for initial programming of a new model memory location can be found on page 70 and the programming examples that begin on page 288.
• When the remote control system is switched on, being bonded or when making settings, that the transmitter's antenna is always far enough away from the receiver's antennas. If the transmitter's antenna is brought too close to the receiver's antennas this will cause receiver over-modulation and its red LED will illuminate. At the same time the return channel will drop out and, as a consequence, the field strength

indicator in the transmitter's screen will be replaced by an "x" and the receiver's current battery voltage display will show
0.0 V. The remote control is then in Fail­Save mode, see page 2248, i. e. servos will remain in their current positions until a new, valid signal can be received. In such a case, increase the distance (between the transmitter and the model containing the receiver) until the indicators are again "normal".
WARNING:
Never switch the transmitter off during model operation! Should it
happen, then keep your nerve and wait until the transmitter display is completely shut down. This takes at least three seconds. Turn on again your transmitter only after that. Otherwise you run the risk that the transmitter immediately after turning “hangs” and, consequently, to lose the control of the model. A restart of the transmitter is possible only after the described procedure.

Preliminary remarks about the GR-32 DUAL receiver
Receiver system
The
mc- 3 2 HoTT remote control set includes a
type GR-32 DUAL, 2.4 GHz bidirectional receiver for connecting up to 16 servos and a receiver GR-12L for connection of up to 6 servos is included.
After switching on this HoTT receiver, should "its" transmitter not be within range or switched off or pos­sibly even the “wrong” model memory in the transmit­ter is active, then the receiver's red LED will illuminate continuously for about 1 s then begin to blink slowly. This indicates the receiver has not (yet) established a link to a Graupner HoTT transmitter. If a link has been established, the green LED will illuminate continu­ously and the red LED will extinguish.
In order to establish a link to the transmitter, the Graupner HoTT receiver must first be "bound" to "its" particular model memory in "its" Graupner HoTT transmitter. This “binding” linkage is only necessary once for each receiver/model memory combination. Refer to pages 84 or 94. This procedure is known as "binding". This “binding” is only once per receiver / model memory combination or - after appropriate conversion of one or more model memory, see page 83 or 93 - even each receiver / transmitter combina­tion is required; the GR-32 DUAL receiver included in the set is pre-bound by factory for the model memory 1, so that the “binding” is only necessary when ad­ditional receivers are used or if you desire to change model memory (and can be repeated at any time).
On-board voltage display
The current voltage of the receiver's power supply will be shown in the right side of the transmitter's screen if a telemetry link exists between the receiver and transmitter:

Temperature warning
Should the receiver’s temperature sink below an adjustable threshold (default value -10 °C) or rise above an adjustable threshold (default value +55 °C), an acoustic warning will be issued by the transmitter in the form of a uniform beep of about 1 s duration. The aforementioned threshold limits are stored and adjusted in the receiver.
Servo connections and polarity
Graupner HoTT receiver servo connections are num­bered. The connectors used are keyed against polarity reversal. Pay attention to the small side chamfers when plugging in these connectors. Never use force.
The four outer, vertical connectors, designated with "B + -" are intended for battery connections.
Do not reverse the polarity of this connec­tion. Reversed polarity could destroy the receiver and devices attached to it.
The supply voltage is bussed across (i. e. common for) all numbered connections. The function of every individual channel is determined by the transmitter used, not by the receiver. It is not only the throttle servo connection which is different for every manufac­turer and model type. For example, in Graupner re­mote control systems the throttle servo is on channel 1 for winged aircraft and on channel 6 for helicopter models.

behaviour in comparison to previous technology. Please take the time to familiarize yourself with this sensitive behaviour.
If you have a speed controller with integrated BEC* arranged in parallel with the receiver battery, its positive pole (red cable) may to be removed from the 3-pole connector. Be sure to look for notices about this in the instructions for the speed controller used.
With a small screwdriver, carefully lift up the connector's centre latch (1) just a bit then pull out the red lead (2) and tape it up with insulation tape to prevent possible short circuits (3).
Follow the installation instructions on page 52 for the receiver, the receiver antenna and for mounting the servo.
Reset
To execute a reset of the receiver, press and hold the SET button on the receiver's top-side while switching the power supply on.
If a receiver reset is done while the transmitter is switched off or on a receiver which is not bound, the GR-32 DUAL receiver's LED will slowly blink red for about 2 or 3 seconds. Now release the button again. The binding process can now be initiated right away on the transmitter-side.
If the reset is done on a bound receiver and the cor­responding model memory is active in the powered on transmitter, the LED will illuminate in green after 2 or 3 seconds as an indication that the transmitter/ receiver system is again ready for operation. Now release the button again.
The signicantly greater servo resolution characteristic of the HoTT system produces a noticeably rmer response

Receiver firmware updates
Secure receiver settings
When also the default set enclosed receiver GR-12L only the red LED lights up for about 3 seconds, then goes out for about 3 seconds and starts to glow red constant after this break.
Release the button once the red LED goes out. If the reset is performed with an unbound receiver, a
binding process can be initiated immediately after­wards.
Please note the following:
A receiver RESET will cause ALL receiver settings, except for binding information, to return to their factory
settings. Therefore if a RESET is triggered uninten-
tionally, any custom settings that had been present in the receiver before the reset will have to be established again by way of the Telemetry menu.
A deliberate RESET is recommended, es­pecially if a receiver is to be "transferred" into another model. This is a rather simple method to eliminate settings which are no longer applicable.
Receiver firmware updates are made by way of the connector located on the side of the receiver and the help of a PC running under Windows XP, Vista or Windows 7 or 8. The included USB interface cable No.7168.6 along with adapter cable, No.7168.6A are needed to run an update. The programs and files also needed can be found as a complete packet in Internet on the Graupner website at www.graupner.de under the downloads for the respective product.
Download this software package, such as the en­trance to the section “Update the transmitter software” on page 50 describes from the related internet page and unzip it on your PC or laptop. For details, please refer to the same internet page detailed instructions.
Note:
After registering your receiver at
https://www.graupner.de/de/service/ produktregistrierung.aspx
you will automatically receive notication of future updates per email.
As you enter the section “Update the transmitter software” on page 50, after having downloaded from the Internet and unzipped on the PC or laptop the software packet, among other things it is included the PC program “Firmware_Upgrade_grStudio” . You may even have already installed this program on your PC or laptop. With the menu item “Receiver settings” this PC program “Firmware_Upgrade_grStudio” it is always possible to save all the settings programmed in a receiver to a file on the PC or laptop, so you also can transfer back to the receiver these if necessary. The otherwise possibly necessary reprogramming of a receiver via the menu “Telemetry” is therefore unnecessary. For this program the default to mc-32 HoTT transmitter set (No. 33032) is included USB interface (No. 7168.6) and also the supplied interface cable (No. 7168.S) are needed. For details, please refer to the place on the internet at the same place detailed instructions.

Installation notices
Receiver installation
Regardless of which Graupner receiver system you use, the procedure is always the same.
Please pay attention that the receiver's anten­nas must be mounted at least 5 cm away
from all large metal parts or any wiring that is not directly routed out of the receiver itself. In addition to steel parts, this also includes carbon fiber parts, servos, fuel pumps and all kinds of cables etc. Opti­mally the receiver should be placed at a readily ac­cessible location that is well away from all other equipment. Under no circumstances may servo ca­bles be wrapped around the antennas or routed close to it.
Please note that cables are subject to the accelera­tion forces which occur during flight and these forces may cause such cables, to shift in position. Therefore be sure the cables in the vicinity of the antennas are not able to move. Such moving cables can cause reception disturbances.
Tests have shown that vertical (upright) antennas provide the best results during wide-range flights. In the case of diversity antennas (two antennas), the second antenna should be oriented at a 90° angle to the first antenna.
The connectors designated "B + -" on the GR-32 DUAL HoTT receiver are intended for battery con­nections. The power supply is bussed across all numbered connections so it can be attached at any of these 16 connectors. However, due to additional voltage losses associated with the traverse connec­tors, connections 13 through 16 should not be used for connecting the receiver's battery.
In the also included in the set GR-12L receiver HoTT , no specially designated connection for power supply is available, so that the battery can generally be con­nected to any free servo connection.
In the GR-12L receiver HoTT the terminals 1 ... 6 are opposite respect to the GR-32 DUAL
receiver, it means they are installed rotated by 180 degrees, which is why all the connecting cables are „upside down“ to insert the GR-12L. If necessary, is to use a V- or Y-cable (No. 3936.11).
The function of every individual channel is determined by the transmitter used, not by the receiver. However, channel assignments can be changed in the receiver by programming done in the »Telemetry« menu. Nevertheless, it is recommended this be done on the transmitter side via the "Transmitter output" option, see page 234.
Several notices and suggestions for installing remote control components into a model are provided below.
1. Wrap the receiver in a foam rubber pad that is at
least 6 mm thick. Attach the foam rubber to the receiver with rubber bands so it will be protected against vibration and/or the jars of a hard landing.
2. All switches must be installed such that they are
not affected by exhaust gases or vibration. The switch knob must be freely accessible over its entire range of movement.
3. Mount servos on rubber bushes/spacers with
hollow brass bearings to protect them from vibration. Do not tighten the fastening screws down too tight as this would negate the vibration protection to be provided by the rubber bush/ spacer.
Only when servo fastening screws are properly tightened will this arrangement provide security and vibration protection for your servos. The figure below shows how a servo is mounted properly. The brass bearings are to be pushed into the rubber bushes/spacers from below.

4. Servo arms must be free to move throughout their entire range of motion. Pay attention that there are no objects which could hinder servo arm motion.
5. Connect the power supply cable as well as the power connection cables to the receiver as shown below ...
Installation notices

Receiver system power supply
... but never so:
ATTENTION:
At the receiver, GR-32 “T” (telemetry) and “S” (“Signal”) servos and other components are connected horizontally only at the termi-
nals 13 to 16. Under no circumstances may be connected across
the other terminals 1 to 12 components and espe cially the receiver battery as shown demonstratively in the figure above. The same applies to the termi­nals 1 ... 6 of the receiver GR-12L. A plug in “cross” over 2 to 3 terminals, immediately leads to a short circuit of the receiver battery; the destruction of possibly connected components and the immediate loss of warranty claims.
The sequence in which servos are connected to the receiver depends on the type of model. Follow the nection layouts provided for this on pages 65 and 69.
Also observe the safety notices provided on pages 4 …
10.
con-
In order to prevent uncontrolled movements of servos connected to the receiver during startup
always rst switch on the transmitter
and then the receiver
and when finished with operation
rst switch off the receiver
and then the transmitter.
When programming the transmitter, be sure that elec­tric motors cannot start running without control or that a combustion motor equipped with automatic starting cannot start up unintentionally. To be safe, disconnect the receiver's drive battery or, in the case of a com­bustion motor, disconnect the fuel supply.
-
fully charged battery, battery leads with adequate cross-section, minimum contact resistances at con­nectors, etc., the transmitter indicates repeated re­ceiver voltage collapses or is receiver voltage is generally too low; please give attention to the follow­ing notices:
Give primary attention to fully charged batteries when model operation is to be started. Be sure that the contact surfaces of connectors and switches really are low resistance. If necessary, measure the voltage drop across installed switch cables when they are under load because even new heavy-duty switches can cause a voltage drop of up to 0.2 V. This value can increase in contacts by factors as a consequence of aging and oxidation. The constant vibrations and jarring also takes its toll on contacts to produce a creeping increase of contact resistance.
Servos present another possible problem source. Even rather small servos like a Graupner/JR DS-281 can draw up to 0.75 A of current when it is blocks un­der load. Just four of these servos in a “foam” model can therefore load down the on-board power supply by as much as 3 A …
A further factor is that 2.4 GHz receivers generally pass control signals to servos at a higher rate than with comparable receivers used in earlier frequency ranges. This equates to shorter “off” periods, which also has an effect on the power consumption of the receiving system. The current drain of many of today’s digital servos is also higher, reflected by their greatly improved ability to hold the prescribed position be­tween control signals.Therefore you should choose a power supply which will not break down under greater loads but rather always deliver sufficient voltage. To “calculate” necessary battery capacity you should always figure on at least 350 mAh for every analog
Among other aspects, the safe operation of a model depends on a reliable power supply. In the event that, despite smooth operating rods,

servo and at least 500 mAh for every digital servo. For example, from this point of view a battery with
1400 mAh would be the absolute minimum to power a receiver system with a total of 4 analog servos. But be sure to also consider the receiver itself into the calculation because its bidirectional functionality will draw about 70 mA of current too.
Regardless, it is generally recommended that you connect the receiver via two cables to the power sup­ply: cable “1” is to be as usual, plugged into the “12 + B” port of the receiver and cable “2” at the opposite, with “11 + B - “label, the end of the edge connector of the receiver.
For example, by using a switch or voltage regulator with two leading to the receiver power supply cable. If necessary, use to connect them to the receiver a V or Y cable No. 3936.11, see figure, if you need one or both terminals of the receiver and to connect a servo, speed controller etc.. They reduce by the double con­nection to the switch or voltage regulator not only the risk of a cable break, but also ensure more power to the connected servos.
If a separate battery is connected to each receiver battery connection, be absolutely sure the batteries have the same voltage and power rating. Never con­nect different battery types or batteries charged to significantly different levels to the receiver. This can lead to effects similar to short circuit conditions. In such cases, insert voltage stabilizers, such as the PRX-5A receiver power supply, between the batteries and the receiver.

Five-cell battery packs offer a greater voltage toler­ance than do 4-cell packs.
However, be aware that not every servo available on the market is able to tolerate the voltage level output by a 5-cell pack over the long term, this is particularly true when the battery pack is freshly charged. Some of these servos react to this with a noticeable “grind­ing” sound.
Therefore pay attention to the specifications
of the servos you use before making a choice
for a 5-cell battery pack..
LiFe 6.6 V batteries with 2 cells
From a contemporary perspective, these new cells are the very best choice.
LiFe cells are also available in hard plastic casings to protect them from mechanical damage. Like LiPo cells, LiFe cells can be quick charged in suitable chargers and they are comparatively robust.
This type of secondary cell battery is also rated for a significantly greater number of charge/discharge cycles than, for example, LiPo batteries The nominal
6.6 V output of a 2-cell LiFe battery pack does not
present a problem for either Graupner HoTT receiv­ers nor for those servos, speed controllers, gyros and other devices which have been specifically approved for operation in this – higher – voltage range.
Please note however that practically all servos, speed controllers, gyros and other devices built in the past and most such
devices currently still offered on the market have
only a permissible voltage range of 4.8 to 6 V. Use of these batteries in conjunction with these devices demand use of a stabilized voltage regulator, e. g. the PRX, No. 4136, see appendix. Otherwise there is danger that attached devices will incur damage within a short period of time.
LiPo 2-cell packs
For a given capacity, LiPo batteries are lighter than, for example, NiMH batteries. LiPo batteries are also available in hard plastic casings to protect them from mechanical damage.
The comparatively high nominal voltage, 7.4 V, for a 2-cell LiPo pack does not present a problem for either Graupner HoTT receivers nor for those servos, speed controllers, gyros and other devices which have been specifically approved for operation in this – high­er – voltage range.
Please note however that practically all servos, speed controllers, gyros and other devices built in the past and most such
devices currently still offered on the market have
only a permissible voltage range of 4.8 to 6 V. Use of these batteries in conjunction with these devices demand use of a stabilized voltage regulator, e. g. the PRX, No. 4136, see appendix. Otherwise there is danger that attached devices will incur damage within a short period of time.
Charging the receiver battery
Charger cable, No. 3021, can be plugged directly onto the receiver’s battery for charging. If the battery in the model is connected by way of an No. 3046, 3934,
3934.1 or 3934.3 power supply cable, then charging can be accomplished via the charging jack or special charging connector integrated into the switch. The switch in the power supply cable must be in its “OFF” position for charging.

Term denitions
Control function, control, function input, control channel, mixer, switch, control switch, fixed switch
To make use of this mc- 3 2 HoTT manual easier, a number of the terms used repeatedly throughout this manual have been defined below.
Control function
A "control function" is to be perceived – initially in­dependent of its signal path – as a signal intended to affect a given control function. For example, this could be for throttle, rudder or aileron in a winged aircraft or pitch, roll or crow for a helicopter.
A control function signal can be applied directly over a single control channel or also through a mixer and then applied over multiple control channels. A typical example of multiple control channels is separately operated aileron servos or the use of two roll or crow servos in helicopters. The control function explicitly in­cludes the influence of the control's mechanical travel on the respective servo. This can not only be spread or compressed by software but even the travel char­acteristic can be modified from linear to extremely exponential.
Control
"Controls" include all operating elements on the trans­mitter, which are directly activated by the pilot, that impose an effect on servos, speed controllers etc. connected to the receiver. This includes:
• both sticks for control functions 1 through 4, whereby these four functions can be freely swapped around for both model types ("winged aircraft" and "helicopters") by way of software "Mode" settings, e. g. throttle left or right. The function for throttle/airbrake control is often referred to as the C1 control (channel 1).
• both proportional controls located on the transmit­ter's sides, which are, for example, given the des­ignations Lv1 (right-side "rotary slider") and Lv2 (left-side "rotary slider") in the »Control adjust« menu, page 118 and 122.
stick
also
• the three proportional sliders in the middle console designated Sl1 … 3, for example as shown in the »Control adjust« menu, page 118 and 122,
• all five proportional rotary controls on the transmit­ter's front side, which are, for example, given the designations DR1 … 5 in the »Control adjust« menu, page 118 and 122,
• the switches present, if they are assigned to a control channel in the »Control adjust« menu.
The proportional operating elements produce a direct effect on servos which is commensurate with the con­trol's position whereas switch modules can only effect a two or three increment change.
Just which of these controls and switches operate which of the servos 5 … 16 (max.) is freely programmable.
Important notice:
Inputs 5 … 15 for helicopters and 5 … 16 for winged aircraft are generally "free", i. e. not assigned, in
the transmitter's basic programming.
Function input
This is an imaginary point in the signal path and must not be considered the same as the point on the circuit board where the transmitter control is connected. The choice of "Stick mode" and settings in the »Con- trol adjust« menu have their effect "downstream" of these imaginary connection points. Thus differences between the physical control's number and the number of the downstream control channel can indeed emerge.
Control channel
From the point at which a signal contains all control information necessary for a particular servo – whether directly from the physical control or indirectly by way of a mixer – the term "control channel" is used.
(The control function “Aileron” in a surface model is so divided, for example the model type “2AIL” in the control channels left and right aileron. Analogously,
e. g. in the Heli type “3sv (2Roll)” the control function splits left and right in the control channels aileron servo.)
This signal is only yet to be influenced by settings made in the menus »Servo adjustment« and »Transmitter output« before it leaves the transmit­ter's RF module.
Once it arrives at the receiver, this signal may still be modified by settings made in the telemetry menu before finally being applied as a control quantity for the respective servo.
Mixer
The transmitter's software contains a variety of mixer functions. These can be used to apply one control function to multiple servos or, conversely, to apply multiple control functions to a single servo. Please look over the numerous mixer functions in the text beginning on page 171 of this manual.
Switches
The four standard toggle switches, the two 3-way switches and both push-button switches can also be incorporated into control programming. However, these switches are generally intended for switch­ing program options, e. g. to start and stop timers, to switch mixers on and off, or as a teacher/pupil switchover, etc. Each of these switches can be as­signed any number of functions.
Appropriate examples are detailed in the manual.
Control switches
Since it is very practical to have some functions auto­matically switched on or off for a certain control's po­sition (e. g. switch on/off of a stopwatch for acquisition of model run time, automatic extension of spoilers and other possibilities), eight control switches have been integrated into
These software switches, designated "C1 … C8", are merely defined by virtue of their contact state along
mc- 3 2 HoTT software.
Term denitions

the physical control's course of travel by the touch of a key. The switching action can be correlated to the physical control's travel direction by software.
Of course control switches can also be freely com­bined with the aforementioned physical switches to solve even more complex problems.
There is a series of instructive examples which make this programming child's play. Learn about this by tak­ing advantage of the programming examples begin­ning on page 268.
Logical switches
These functions permit two switches, control switches and/or logical switches or any combination of these to be combined with one another to create logical "AND" and "OR" functionality. A total of 8 logical switches, "L1 … L8" can be programmed, see page 138.
Fixed switches FXI and FX
This type of switch turns a function, e. g. a timer, per­manently on (closed fixed switch) or off (open fixed switch) or they can provide a fixed input signal for a control function, e. g. FXI = + 100 % and FX = -100 %. For example, in flight phase programming, these fixed switches can be used to switch a servo or speed con­troller between two settings.

Physical control, switch and control switch assignments
Principle procedure
Maximum fl exibility is offered by the mc-3 2 Hott system when it comes to assigning standard equip­ment operating elements to certain functions.
Since the assignment of controls and switches is done in the same way, even though different menus may be involved, it is appropriate at this point to explain the fundamental programming technique so that users can concentrate on the particular contents when reading the detailed menu descriptions.
Physical control and switch assignments
The third column of the »Control adjust« menu (see page 118 to 122) can be used to assign transmitter inputs 5 … 16 to operate servos ...

Notes:
The control will only be recognized beyond a certain amount of travel. Therefore these
controls can be moved back and forth until the correct assignment is shown in the display. If adjustment travel is insuf cient, activate the control in the other direction.
On the other hand, if the »Control switch« menu, page 146, is used to assign a control, the message shown below will appear:
Switch assignment
Wherever programming permits a switch to be as­signed, a switch symbol will appear in the screen's bottom display line.
Use the selection keys in the left or right touch pad to select the appropriate column.
How to assign a switch
1. Briefl y touch the SET key of the right touch pad.
The message shown below will appear in the screen.
Move desired switch to ON position (ext. switch: ENTER)
2. Now it is only necessary to put the selected switch
into the desired "ON" position or, as described at the right in "Assignment of external switches", to select a switch from the list of "External switches". This concludes the assignment. The switch symbol to the right of the switch's number indicates the current state of the particular switch.
Changing switch action
If the activation of a switch is to result in the oppo­site action, put the switch or stick in the desired OFF position, again activate the switch assignment and reassign the switch again so it will respond with the desired action.
Clear switch
A switch which has been assigned as described un­der point 1 can be cleared with a brief simultaneous tap on the  or  key combination in the right key pad (CLEAR).
Assignment from the "external switch" list
Those menus in which the message …

… appears permit the assignment of switches be­longing to the so-called "external switches".
Do this by confi rming the message text with the SET key. A new window will appear with a list of the eight control switches "C1 … C8", followed by two so-called "FX" fi xed switches and the eight logical switches "L1 … L8".

»Control switch« menu, page 146.
Two switches and/or also control switches can be
combined with one another to form the logical "AND" or "OR" functions via the »Logical switch« menu, see page 150. A total of 8 logical switches "L1 … L8" (as well as another 8 inverted logical switches with inverted switching direction) are available.
The result of a logical switch function can also be used as an input for another logical switch function. Refer to the appropriate menu for more details about this.

All switches mentioned can have multiple
assignments. Pay attention that you do not UNINTENTIONALLY assign reciprocally conicting functions to a single switch. If necessary, note down the given switch functions.
Typical applications:
Shut-off of an on-board glow plug heater upon
underrun or overrun of an idle threshold point programmed for the C1 stick. In this case the glow plug heater switch is controlled by a transmitter mixer.
Switching for some special functions may be better implemented from a certain freely programmable control position

pure "ight time" for a helicopter by way of a control switch on the throttle limiter.
Automatic switch off of the "AI Rud" mixer when
brake aps are extended, for example to adapt the roll of a model to the ground when making a landing on a slope without inducing a change of ight direction due to inuence on the rudder.

Digital trimming
Functional description and description of C1 cut-off
Digital trim with visible and audible indicators
Both sticks are equipped for digital trimming. By de­fault, turning trim wheels will offset the stick's neutral position by 4 increments (out of a possible 100 steps per side). This offset is also reported acoustically. A brief press on the trim wheel will reset an existing trim offset back to "0". Any other "zero points" can be specified with the help of the »Trim memory« menu. If flight phases have been created and each assigned with a fitting name in the »Phase settings« (page
154) and »Phase assignment« (page 160) menus, then these names will appear at the bottom left in the »Trim memory« menu (page 240 to 242) and their trim values will be stored on a flight-phase specific basis.
The default 4-steps per click increment range placed in every new model memory upon initialization can be changed at any time in the »Stick mode« menu, page 114 or 116, separately for each stick plane, in a range of 1 … 10 for fixed-wing models and in a range of 0 … 10 for helicopter models. (A trim function can be deactivated by selecting "0" steps, which can be advantageous in helicopters with certain gyro sys­tems.)
Current trim values are automatically stored when a model memory change is made. Furthermore, – ex­cept for the trim of the throttle/airbrake stick, the so-called "C1"(channel 1) control function – digital trim can be set to operate globally or on a flight-phase specific basis within a memory location. This choice is made, separate for each stick plane, in the second column of the »Stick mode« menu, page 114 or 116.
Notes:
on the trim wheel will reset trim to "0" or, in the »Trim memory« menu, will reset a stored ight- phase specic trim value.
The "cut-off trim" function, known from other
Graupner remote control systems in the mc and
mx series, and typically described in this section can be realized with the help of the "Thr. CutOff" option in the »Basic settings, model« menu, see page 90 and 101.

Winged models
EL AI
Convenient support is provided for up to four aileron servos and four flap servos on normal models or, for V tail and flying wing/delta models, up to two aileron/ elevator servos plus four flap servos.
The majority of motorized and glider models belong to the tail unit type "normal" and are equipped with one servo each for elevator, rudder and ailerons in addition to a motor throttle or electronic speed con­troller (or for brake flaps in the case of a glider mod­el). Beyond this, tail unit type "2 HR Sv 3+8" permits the connection of two elevator servos to receiver outputs 3 and 8.
"V-tail" is to be selected from the »Model type« menu if the model has a V-tail instead of a "normal" tail. This V-tail option provides coupled control functions for elevator and rudder such that both tail flaps – each controlled by a separate servo – are able to handle both elevator and rudder functionality.
For delta and flying wing aircraft models, aileron and elevator functionality is affected by way of a common rudder flap on the trailing edge of each side (right and left) of the wing. The program contains appropriate mixer functions for both servos.
If ailerons, and conditionally the flaps, are each actu­ated with two separate servos then settings can be made for differentiated control of all aileron and flap pairs in the »Wing mixers« menu, i. e. settings for downward rudder throw independent of upward throw. And finally, the positioning of flaps can also be con­trolled by one or even more of the three proportional sliders or the seven proportional rotary controls.
Alternatively, there is a phase-dependent trim func­tion available for flaps, ailerons and elevators in the »Phase trim« menu.
Up to 8 flight phases can be programmed into each of the 80 model memory locations.
Except for C1 trim, digital trim will be stored on a flight-phase basis. C1 trim permits easy location of a carburettor idle setting.
Two timers are always available for flight operation. The transmitter operating time expired since the last battery charge is also displayed.
All transmitter controls and switches can be assigned in the »Control adjust« menu to inputs 5 … 16 with almost no restrictions.
The "Dual Rate" and "Exponential" functions for
ailerons, rudder and elevators are separately pro­grammable and each are convertible between the two variations on a specific flight-phase basis.
In addition to 8 freely allocatable linear mixers, 4 curve mixers (»Free mixers« menu) and 4 dual mixers (»Dual mixer« menu) there are also flight-phase de- pendent 8-point curves available to control channel 1 (throttle/brake), see »Channel 1 curve« menu.
Depending on the number of wing servos, fixed­definition mix and coupling functions can be selected from a list in the »Wing mixers« menu.
• Multi-flap menu: control of flaps as ailerons, the in­fluence aileron trim on flaps controlled as ailerons, flap differentiation, flap function throw magnitude for all aileron and flap pairs, ailerons controlled as flaps, elevator mixer flaps
• Brake settings: butterfly, differential reduction, elevator curves
• aileron rudder mixer

Helicopter models
The advanced developments incorporated into the transmitter as well as those now in helicopter models and their components like gyros, speed regulators, rotor blades, etc. make it possible to master a heli­copter even in 3D acrobatic flight. On the other hand, a beginner needs only a few settings to get started with hovered flight training then, step-by-step, take advantage of mc- 3 2 HoTT features with increasing expertise.
mc- 3 2 HoTT program can operate all con-
The ventional helicopters having 1 … 4 servos for pitch control.
Seven flight phases plus autorotation are available within a model memory, see menus »Control adjust«, »Phase settings« and »Phase assignment«.
As with winged aircraft, here too, in addition to the basic screen's standard timers there are additional timers as well as a lap counter with flight-phase­dependent stopwatch functionality which are available for selection (menus »Timers (general)« and »Fl. phase timers«). Except for pitch/throttle trimming, digital trimming can be stored as "global" for all flight phases or as "flight phase specific". C1 trim permits easy location of an idle setting.
The control assignments for inputs 5 … 16 is made separately for each flight phase (»Control adjust« menu).
A flight phase copy function is helpful during flight tri­als (»Copy / Erase« menu).
"Dual Rate" and "Exponential" functions can be cou­pled for roll, nick and tail rotor and programmable in two variations in every flight phase.
There are 8 freely assignable linear mixers. There are also 4 curve mixers that can be programed and these can also be switched on or off, depending on the flight phase, in the »MIX active/phase« menu. Beyond this, there are also 4 dual mixers available.
The »Helicopter mixer« menu provides flight-phase­dependent 8-point curves for the non-linear charac­teristics pitch, throttle and tail rotor mixer as well as two independent swashplate mixers each for roll and nick. Independent of this, the control curve of the channel 1 stick can be defined with up to a total of 8 points in every flight phase. The beginner will initially only adapt the hover flight point to the control middle for the non-linear characteristics.
Pre-programmed mixers in the »Helicopter mixer« menu:
1. Pitch curve (8-point curve)
2. C1 throttle (8-point curve)
3. Channel 1 tail rotor (8-point curve)
4. Tail rotor throttle
5. Roll throttle
6. Roll tail rotor
7. Pitch-axis throttle
8. Pitch-axis tail rotor
9. Gyro suppression
10. Swashplate rotation
11. Swashplate limiter
The "Throttle limit" function (input Tl16 in the »Con- trol adjust« menu) allows the motor to be started in any flight phase. From firmware version 1103 the right-side proportional rotary slider is no more as­signed to input "Tl16" by default. This "throttle lim­iter", which can however always been set again if necessary, establishes – depending on its given posi­tion – the maximum possible throttle servo position. This makes it possible for the motor to be controlled in the idle range, if necessary even by the proportion­al regulator. The throttle curves become effective only when the proportional regulator is pushed toward the full throttle direction.

Detail program description
Loading a new memory location
Anyone who has worked through to this part of the manual has certainly already tried out a bit of pro­gramming. Nevertheless a detailed description of every menu should not be left out.
This section begins with the loading of a "free" mem­ory location, a procedure which would be performed if a new model was being "programmed".

From the basic display, a jump to the "Multi-function list" is made with a tap on the centre SET key of the right touch pad. (The centre ESC key of the left touch pad will cause a jump back to the basic display.) By default, when the multi-function list is called for the first time after switching on the transmitter, the »Mod- el select« menu option will be active and displayed in inverse video. Otherwise use the  or  selec­tion keys of the left or right touch pad to select the »Model select« menu option, whereby the upper of the two following figures shows a selection list for a fixed-wing model and the lower shows the selection list for a helicopter model.

In the transmitter's delivered state, the first model memory is initialized to the "xed-wing model" type and the receiver in the delivery is "bound" to this model. The time display located near the line's middle indicates the overall operating time of the respective model memory.
In the above example E16 in dark font on a light background.
On this view it can be seen that the receiver is “spe­cific memory” associated with the default option set with the model memory 1 so that it only responds to the control signals that a model memory of his sta­tion. For details, see page 83 or 93.

Afterward you will be prompted to select the basic model type, i. e. either "winged model" or "helicopter model".
Select model type ( free model memory )
Use the or keys of the left or right touch pad to select the basic model type then tap on the centre
SET key of the right touch pad. This initializes the
selected model memory with the selected model type and the display will return to the base screen. The memory location is now accordingly occupied.
Changing over to another model type is still possi­ble if you fi rst erase this memory location (»Copy / Erase« menu, page 74).
Notes:
If the currently active model memory is to
be erased then immediately after the erase
action one of the two model types, "Winged" or "Heli" must be de ned. You cannot avoid this selection even if you switch the transmitter off. When the transmitter is switched on again the undesired occupation of the that model memory will have to be erased from another memory location.
If a non-active memory location is erased, it will subsequently be marked as "free" in the "Model select" menu.
After the selected model memory is initialized with
the desired model type, the display will switch to the base screen of the freshly occupied model memory. At this time the warning …
BIND. N/A

… will appear for several seconds as noti cation that a binding connection to a receiver is "not
available". A brief tap on the centre SET key of the right touch pad will cause a direct jump to the
appropriate option.

If the screen should display the warning …
Throttle too high!
… then move the throttle stick, or the limiter for a helicopter, (by default this is the right rotary slider Lv1) into its idle position.
Whether or not this warning appears also depends
on the settings selected for the "Motor on C1" and "Pitch min." options in the »Model type« menu, see page 104, or »Helicopter type« menu, see page 108. For winged aircraft models, select "None" to deactivate this message if you have no
motor
to enter.
If the transmitter already has occupied model
memories then sub-menus of the »Copy / Erase« menu will display a pictograph of the selected model type at the respective memory location followed by a blank line or the model
name which was entered in the »Basic settings, model« menu, page 82 or 92. To
the right of this will be as display of the model operating time and, if present, "Info" about the model.
If battery voltage is too low, the model switchover
cannot be made due to reasons of safety. An
appropriate message will appear in the screen:

As a basic principle, there are four different ways to assign the four control functions, aileron, elevator, rudder and throttle or brake fl aps for winged models as well as rolling, pitching, tail rotor and throttle/pitch for helicopter models, to the two sticks. Just which of these methods is used depends on the preferences of the individual model pilot. This function is set for the currently active model memory in the "Stick mode" line of the »Basic settings, model« menu, page 82 or 93.

With either model type, this situation will only change after appropriate assignments have been made in the »Control adjust« menu.
On the other hand, if a newly initialized model mem­ory is to be put into operation then it MUST first be appropriately "connected" with one or more receivers before the servos attached to the receiver/s can be operated. More about this can be found in the section "Binding" on page 118 or 122.
A fundamental description of programming steps for a winged aircraft model can be found in the program­ming examples section beginning on 288, or for heli­copter models beginning on page 328.
The menu descriptions below are arranged in the sequence individual menus are listed in the multi­function list.

A newly initialized helicopter model is also able to more-or-less move servo 6 – depending on the posi­tion of the right-side proportional rotary slider, which is the default throttle limiter control.

As many as 80 complete model settings, including digital trim values for the trim wheel, can be stored. Trimming is stored automatically such that a switcho­ver from one model to another does not cause a loss of current trim settings. To the right of the model number, each occupied model memory line in this display shows a pictograph of the model type as well as the model’s name entered for the model in its »Basic settings, model« menu, page 76 or 84. The code, if present, for the receiver “bound” to the model memory location will appear right in the line.
Now, with the  selection keys of the left or right touch pad, select the desired model memory from the list and activate it with a tap on the SET key. A tap on the ESC key will cause a return to the previous menu page without activating a model change.

Options are not deactivated by being suppressed. They will simply no longer appear in the list. This also blocks direct access to these functions.
Tip:
If you wish to forgo access-blockage to the multi-function list altogether, suppress the »Code lock« menu in the multi-function list
by way of this menu as a precautionary measure. It is then not so easy for an unauthorized person to lock up the transmitter.

The mc- 3 2 transmitter has a HoTT RF module as standard equipment. In addition to the built-in mod­ule, there is a connector for an external RF module behind one of the two front cover flaps (see page 25) and a switchover to an external module connected there can be affected per software. To do this, use the selection keys of the left or right touch pad to move the marker frame left to the "Module" selection field above the "SEL" column label.
HoTT
To be able to connect to the transmitter, Graupner HoTT receiver must be connected to at least one model memory “of their” Graupner HoTT transmitter. This process is commonly referred to by the English term “binding” and can be repeated anytime. This “binding” of a receiver is by default always memory­specic, but may at any time and for any unbound model memory of a transmitter in the menu that appears row “binding type”, see above, to transmitter specic, and can be reversed, changed.
Important notices:
During the binding procedure be sure the transmitter’s antenna is always far enough away from the
receiver’s antenna.

To be on the safe side, keep them at least one meter apart. Otherwise there is a risk of a faulty connection to the return channel and malfunctions will result.
• Pay close attention to the correct power supply of the receiving system. Too low supply voltage while responding the LEDs of the receiver as described below on your Binding effort, yet there is no proper HoTT Synchronization.
• When binding additional receivers, note that any other – switched on – receivers already bound to the transmitter will fall into Fail safe mode during the transmitter-side “binding” period.
“Binding” multiple receivers per model
Multiple receivers per model can be bound if desired, whereby for managing up to two receivers directly and for di­viding up the transmitter’s 16 control channels (max) in any arrangement among these receivers under menu control. Refer to additional details further down in this section. First bind the receivers individually as described below.

Any telemetry sensors which may be built into the model should therefore be connected to this receiver because the transmitter only receives and evaluates data from the return channel of the receiver activated on this line. The second, and all other receivers, operate in parallel but are fully independent in slave mode.
"Binding" transmitter and receiver
Use the  selection keys of the left or right touch pad to move into the "Module" line. The marker frame will be positioned by default to the column for the next free binding channel.

On the other hand, should the LED on the receiver blink red for longer than about 10 seconds, the binding process has failed. In this case the screen will continue to show the status as "n/a". If this should happen, try changing the position of anten­nas then repeat the entire procedure.

At the receiver, the red LED lights. Press and hold the SET button on the receiver until the red LED goes out after about 3 seconds for a further 3 sec­onds. You can now release the SET button on the receiver. As long as the LED is off, the receiver is in bind mode. Start now-as described above-within these 3 s to bind the receiver to the current model memory. If the LED of the receiver is still dark and the display in the transmitter changes to “b”, the binding process has been completed success­fully. However, the red LED will light up red again at the receiver, the binding process has failed. At the same time appear in the line “module” of the display again “n / a”. If necessary, change the positions of the antennas involved and repeat the entire procedure.

As mentioned in the introduction to the "Binding receiv­ers" section, this menu item of the mc- 3 2 HoTT offers both the opportunity to freely divide up the trans­mitter's control channels within a receiver as well as the opportunity to distribute the transmitter's 16 control channels across as many as four receivers. This re­distribution is subsequently referred to as "mapping" or "channel mapping" (channel correlation). Select the receiver to be "mapped" with the selection keys of the left or right touch pad then tap briefly on the centre
SET key of the right touch pad.
Channel mapping within a receiver
Analogous to the channel correlation function in the »Telemetry« menu on page 249, described as "Channel Mapping", it is very simple to use this menu item to freely assign the transmitter's control channels present on the receiver's inputs to any specific receiv­er outputs (servo connections) for the bound receiver designated by the column labelled BD1.

BUT CAUTION:
If, for example, "2AIL" has been specified in the "Aileron/camber flaps" line of the »Model

Examples:
You would like to control each aileron of a large
model with two or more servos. Assign each of the appropriate outputs (servo
connections) to one and the same input (control channel). In this case, depending on left or right wing, as the respective input to one of the two default aileron control channels (2 or 5).

Perform a range test on the Graupner HoTT system ac­cording to the following instructions. If necessary, have someone assist you in carrying out the range test.
1. Preferably, the receiver already bound to the transmitter should be installed into the model in its intended position.
2. Switch remote control on and wait for the green LED to light up on the receiver/s. Now servo movements can be observed.

3. Place the model on a level surface (pavement, low-cut grass or bare ground) such that receiver antennas are at least 15 cm above ground level.
It may be necessary to put something under the model to raise it up enough for this.
4. Hold the transmitter at hip level and at some distance from one's body. Do not point the antenna directly at the model but rather turn and/ or kink the antenna's end so that it is oriented vertically during the test.

When the range test has been initiated, the transmitter's transmission power will be signifi cantly reduced and the green LED just to the right of the main switch on the transmitter, marked RF, will begin to blink; this will also be accompanied by acoustic tones. At the same time, the timer in the transmitter's display will start counting down and every 5 seconds a two­frequency tone will sound.
Five seconds prior to the end of the range test a three-frequency tone will sound once every second. After expiration of the range test's 99th second the transmitter will again be switched to full output power and the green LED just to the right of the main switch on the transmitter will again illuminate constantly.
6. Move away from the model while manipulating the sticks during this timespan. If you notice an interruption anytime while still within a distance of about 50 m, try to reproduce this malfunction.
7. If there is a motor in the model, it may be necessary to switch it on to further check noise immunity.
8. Continue moving away from the model until perfect control is no longer possible.
9. Wait at this distance for the remainder of the test period with the still-operationally-ready model to expire. After the range test is ended it should again respond correctly to all RC controls. If this is not 100 % the case, do not use the system. Contact your area's Graupner service partner.
10. Perform the range test before each fl ight and, in doing so, simulate all servo movements which also take place during fl ight. The range must always be at 50 m on the ground in order to assure safe model operation.
Caution:
Never start the range test on the transmitter during normal operation of the model.

Motor cutoff (Thr. CutOff)
Note:
This menu line is suppressed if "None" or "None/inv" is selected for the "Motor on C1" line.
Depending on the "idle forward or back" choice made in the "Motor on C1" line of the »Model type« menu (see page 104), this motor "cut off" option can be coupled to a switch for throttling down a speed con­troller or to move a servo on the carburettor of a mo­tor to the OFF position. This option not only replaces the"Cut-off trim" function known from other Graupner mc and mx transmitters but also serves as an Emer­gency-OFF function at the same time, which was not possible with the"Cut-off trim" function.
This motor OFF position (Thr. CutOff) is specified in the left column field over the column label SEL and its value is to be established through trial and error.
A speed controller or throttle servo will only take on this preset position when a certain servo position or threshold is underrun and a switch is activated. This is done by setting the desired servo position (threshold value) into the middle column field, directly over the column label STO, then selecting the appropriate ON/OFF switch function in the right column.
• If the percentage value specified for the middle column is greater than the current servo posi­tion, i. e. the current servo position lies below the threshold, the switchover will occur as soon as the switch is put into its ON position.
• If the percentage value specified for the middle column is less than the current servo position, i. e. the current servo position is above the threshold, the speed controller will initially reduce motor
speed or close the carburettor's throttle servo only to the extent dictated by the value in the left col­umn as soon as the servo's position once under- runs the threshold (max. +150 %) after the switch is changed over to its ON position.
The speed controller or throttle servo will remain in this cut-off position only until the selected switch is again changed over followed by a one­time throttle servo or speed controller movement beyond the preset threshold with the throttle/brake stick control.
The factory setting for the left column is -100 % for the throttle servo "cut-off" position and a threshold of +150 % servo position setting in the middle column.

The – upper – preset value in the middle column ensures the motor can be stopped, throughout the maximum possible positioning range of the servo or speed controller, alone by the switch to be assigned in the right column.
However, if you wish to set a lower threshold, by which an underrun will cause the throttle servo or speed controller with closed switch to switch into the cut-off position, reduce the preset servo travel from +150 % by placing the throttle servo or speed control­ler into the desired position with the throttle/brake stick then touch the centre SET key of the right touch pad.

The "Auto trim" option makes it possible to trim a model quickly and without complications, e. g. in the context of a first-flight or even after (major) repairs, etc.
Typically such test flights are initially flown with sticks counter operated until the desired state of flight is achieved. This generally involves working the trim con­trols during the flight to "unburden" the sticks.
This is exactly what the "Auto trim" function is for. After the desired flight attitude has been achieved via control functions 2 … 4 (aileron, elevator and rudder), the switch assigned to "Auto trim" – ideally one of the standard-equipment momentary switches in the switch panels – is to be activated ONCE.

Module
BASIC SETTING,MODEL Model name Info Stick mode Module
The mc- 3 2 transmitter has a HoTT RF module as standard equipment. In addition to the built-in mod­ule, there is a connector for an external RF module behind one of the two front cover flaps (see page 25) and a switchover to an external module connected there can be affected per software. To do this, use the selection keys of the left or right touch pad to move the marker frame left to the “Module” selection field above the “SEL” column label.
HoTT
To be able to connect to the transmitter, Graupner HoTT receiver must be connected to at least one model memory “of their” Graupner HoTT transmitter. This process is commonly referred to by the English term “binding” and can be repeated anytime. This “binding” of a receiver is by default always memory­specic, but may at any time and for any unbound model memory of a transmitter in the menu that appears row “binding type”, see above, to transmitter specic, and can be reversed, changed.

To be on the safe side, keep them at least one meter apart. Otherwise there is a risk of a faulty connection to the return channel and malfunctions will result.
• Pay close attention to the correct power supply of the receiving system. Too low supply voltage while responding the LEDs of the receiver as described below on your Binding effort, yet there is no proper HoTT Synchronization.
• When binding additional receivers, note that any other – switched on – receivers already bound to the transmitter will fall into Fail safe mode during the transmitter-side “binding” period.

Multiple receivers per model can be bound if desired, whereby for managing up to two receivers directly and for di­viding up the transmitter’s 16 control channels (max) in any arrangement among these receivers under menu control.

Any telemetry sensors which may be built into the model should therefore be connected to this receiver because the transmitter only receives and evaluates data from the return channel of the receiver activated on this line. The second, and all other receivers, operate in parallel but are fully independent in slave mode.
“Binding” transmitter and receiver
Use the  selection keys of the left or right touch pad to move into the “Module” line. The marker frame will be positioned by default to the column for the next free binding channel. In the example shown in the figure below, the marker frame is positioned above the column label “BD2” because the binding channel in the column labeled “BD1” is already in use by default for the receiver which was delivered with the set.

mitter control function 2 (roll) which is divided up into control channels 1 & 2 for left and right roll servos for the "3Sv(2Roll)" option in the »Heli type« menu; then "map" the corresponding transmitter outputs, in this case for channels 1 & 2 (= inputs to the receiver) accordingly.
The number of lines available in the list
(outputs) corresponds to the maximum
number of servos which can be attached to
the given receiver.
If you see the warning …
CAN‘T
RECEIVE
DATA
OK
… then there is no bound receiver within range. If the case may be, switch the RF module or/and your receiving system on.
• With the »Tx. output swap« option, available on the
mc- 3 2 transmitter, see page 234, the
transmitter’s control functions can be interchanged in any way; it is also possible to assign multiple outputs to one and the same control function. In the interests of clarity however we strongly advise that you use only one of these two options.
Channel assignment on other receivers
As already mentioned, the “Rcv Ch map” menu option can be used to freely distribute the
mc- 3 2 HoTT
transmitter’s 16 control channels across up to four receivers, whereby the numbering of outputs (servo
connections) as well as the maximum number of available lines (outputs) will correspond to the maxi­mum number of servo connections available on the given receiver.
RECEIVER CHANNEL MAP BIND2 Rx Input Ch 16 Rx Input Ch 16
Rx Input Ch 16 Rx Input Ch 16
Rx Output Ch 1 Rx Output Ch 2 Rx Output Ch 3 Rx Output Ch 4
After selection of the desired output with the selection keys of the left or right touch pad, the respective input fi eld will be framed.
Tap the centre SET key of the right touch pad. The current setting will be displayed in inverse video. Now select the desired input channel with the selection keys of the right touch pad. For example, suitable to the above rudder example.
RECEIVER CHANNEL MAP BIND2 Rx Input Ch 4 Rx Input Ch 4 Rx Input Ch 4 Rx Input Ch 4
Rx Output Ch 1 Rx Output Ch 2 Rx Output Ch 3 Rx Output Ch 4
Note:
The number of lines available in the list (outputs) corresponds to the maximum number of servos which can be attached to the given receiver.
RF transmit
This menu line provides an option for manually switching the transmitter’s RF transmission on and off to specifi c models while the transmitter is in op­eration. For example, to save power while a model is being programmed.
If this line option was set to OFF, it will be canceled (i. e. set to ON) the next time the transmitter is switched on.
If necessary, use the  selection keys of the left or right touch pad to move into the “RF transmit” line then activate the option with a brief tap on the centre
SET button of the right touch pad.

Range test
Note:
This menu line is when “EXT. PPM “in the

The built-in range test reduces transmission power to an extent that a functional test can be carried out even within a distance of less than 100 m.
Perform a range test on the Graupner HoTT system ac­cording to the following instructions. If necessary, have someone assist you in carrying out the range test.
1. Preferably, the receiver already bound to the transmitter should be installed into the model in its intended position.
2. Switch remote control on and wait for the green LED to light up on the receiver/s. Now servo movements can be observed.
3. Place the model on a level surface (pavement, low-cut grass or bare ground) such that receiver antennas are at least 15 cm above ground level.
It may be necessary to put something under the model to raise it up enough for this.
4. Hold the transmitter at hip level and at some distance from one’s body. Do not point the antenna directly at the model but rather turn and/or kink the antenna’s end so that it is oriented vertically during the test.
5. If necessary, use the  selection keys of the left or right touch pad to reach the “RF range test” line in the menu then start range test mode with a tap on the centre SET key of the right touch pad.

When the range test has been initiated, the transmitter’s transmission power will be signifi cantly reduced and the green LED just to the right of the main switch on the transmitter, marked RF, will begin to blink; this will also be accompanied by acoustic tones. At the same time, the timer in the transmitter’s display will start counting down and every 5 seconds a two­frequency tone will sound.
Five seconds prior to the end of the range test a three-frequency tone will sound once every second. After expiration of the range test’s 99th second the transmitter will again be switched to full output power and the green LED just to the right of the main switch on the transmitter will again illuminate constantly.
6. Move away from the model while manipulating the sticks during this timespan. If you notice an interruption anytime while still within a distance of about 50 m, try to reproduce this malfunction.
7. If there is a motor in the model, it may be necessary to switch it on to further check noise immunity.
8. Continue moving away from the model until perfect control is no longer possible.
9. Wait at this distance for the remainder of the test period with the still-operationally-ready model to expire. After the range test is ended it should again respond correctly to all RC controls. If this is not 100 % the case, do not use the system. Contact your area’s Graupner service partner.
10. Perform the range test before each fl ight and, in doing so, simulate all servo movements which also take place during fl ight. The range must always be at 50 m on the ground in order to assure safe model operation.

Caution:
Never start the range test on the transmitter during normal operation of the model.
DSC output
If necessary, use the  selection keys of the left or right touch pad to switch to the “DSC Output” line then, with a brief tap on the centre SET key of the right touch pad, activate the value window:

SET SET SEL SET
Now you can use the right selection keys to choose between four types of modulation “PPM10”, “PPM16”, “PPM18” and “PPM24”. Touch the centre SET key of the right touch pad again to complete the entry.
This choice primarily influences the maximum num­ber of control channels which can be attached to the DSC (direct servo control) socket, and thus also avail­able to a flight simulator or teacher/pupil system. By selecting “PPM10” this will be control channels 1 … 5, for “PPM16” channels 1 … 8, for “PPM18” channels 1 … 9 and for “PPM24” channels 1 … 12.

Autorotation
Autorotation is that state of descending flight in which the pitch of main rotor blades are set such that the rotor's speed matches the natural forces of air flowing through, like a windmill. This built-up energy can be used for "recovery" lift to brake a descent by appropri­ate blade pitch adjustment.
Autorotation is a means by which real and model heli­copters are able to land safely in emergency situations, e. g. in the event of a motor failure. However, the pre­requisite for this is a well-trained pilot familiar with the helicopter's characteristics. Quick reaction and good perceptiveness are necessary because the rotor's iner­tia can only be used once to generate recovery lift.
When this technique is evaluated during competi­tions, the motor must be switched off for autorotation. On the other hand, for training mode it is advanta­geous to keep the motor at idle for autorotation.
The Autorotation switch causes a switchover to the autorotation flight phase in which control of "throttle" and "pitch" are separate and all mixers which have an effect on the throttle servo are switched off. Cor­responding parameter settings are made in the »Heli- copter mixer« (see text beginning page 190); refer also to the "Principle of the Auto. C1 Pos." topic which follows.
The "Autorotation" name is permanently assigned to this phase and it is included in the base screen and the screeens of all flight phase dependent menus. This name can NOT be changed. It is only possible to assign a switch to this option at the right of this display, as described on page 60. If a switch is assigned,
it will have absolute priority over all other ight-
phase switches.
