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
4
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 signicant 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

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

• 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.

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.

mc-16 and mc-20
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-24Graupner/JR computerized
remote control system, the
control system has been especially developed for ex-
mc- 3 2 HoTT remote
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

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.
Transmitter power supply
The
mc- 3 2 HoTT transmitter is equipped with a
high-capacity, rechargeable LiIo 1s6p/6000 3.7 V
TX battery (No. 33000.1) as standard equipment.
(changes reserved)
However, the standard built-in battery is
not charged upon delivery of the transmitter.
When the transmitter is used, its battery voltage should
be monitored by way of the indicators provided in the
LCD display. If the voltage level preset in the "Battery
warning" line of the »General basic settings« menu,
page 279, (default setting 3.60 V) is underrun, an

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.

Lithium battery CR 2032
On the side of the transmitter board opposite the
transmitter battery there is a fi xture containing a
lithium battery, type CR 2032, which can be replaced
by the user.
Lithium battery
This battery maintains the date and time
settings during a transmitter power supply
outage, for example when the transmitter's
main battery is being replaced.
General charging instructions
•
•
ter, the transmitter charging current should generally not exceed 1.5 A. Limit the charge current if
necessary.
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-

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.

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 "

3. Connect the other end of the cable to the desired
unit in compliance with the given operating
instructions for that unit.
Important:
Pay attention that all plugs are inserted
securely into their respective sockets
and use only the prescribed 2-pole TRS
connector plugs on the DSC-side.
4. In the line "DSC Output" in the »Basic settings,

CAUTION:
For direct connection of your transmitter to a
PC or a laptop via cable (DSC-cable) and / or
PC interface for your simulator it may
possibly result in destruction of the transmitter by
electrostatic discharge! This type of connection may
therefore only be used if you are, for example, using

carrying out a software update via
a PC is described in next paragraphs.
The PC software required, as well as the suitable
USB driver, can be found on the download page for
the given product on the Graupner website at
www.graupner.de.
Once the necessary driver and software is installed
on the PC, this USB connection can be used to update the transmitter or even just to set the transmitter's date and time.
To set the transmitter's date and time by way of this
jack, refer to the »Info display« menu, beginning
page 286.
The so-called "DATA jack" is located at the right of
this group of connector sockets.
This jack is intended for connection of the optional
Smart-Box, No. 33700.
Details about the Smart-Box can be found with the
given product in the Graupner RC main catalog or in
Internet at www.graupner.de.
However, the Data socket can also be used to connect external RF modules made by other manufacturers; see “EXT.” and “SP.” in the “Module” section of the
“Basic model settings” menu on pages 86 and 96.
The operation of a Smart-Box or a Bluetooth
module, see below, is generally not possible
in the “SP mode”.

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.

Otherwise the graph bars show current setting percentages for stick control functions which are not
self-neutralizing – typically for the "C1" throttle/brake
or throttle/pitch stick. 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

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 /

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.

Now switch the RF module off by tapping on the

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.

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.

• 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

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

Receiver initialization
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.

• 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.

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.

you will automatically receive notication 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

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,
Receiver power supply

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.

Receiver system power supply
NiMH 4-cell battery packs
In compliance with the aforementioned conditions,
your Graupner HoTT receiver system can be readily
operated with traditional 4-cell battery packs as long
as the packs have adequate capacity and voltage
level.
NiMH 5-cell battery packs
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

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 denitions
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 denitions

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

page 118 to 122) can be used to assign transmitter

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 …
Move desired switch

(ext. switch: ENTER)
… 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

switch.
To this end, there are a total of 8 so-called "control
switches", C1 … C8, available whose switching
direction can be established, even inverted, in the
»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.
• The two FX switches switch a function on "FXI" or
off "FX
• All switches mentioned can have multiple
assignments. Pay attention that you do not
UNINTENTIONALLY assign reciprocally conicting
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
" permanently.
• Automatic switch on/off of the timer to measure
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 inuence on the rudder.
• Extending landing aps with elevator trim adjustment
during a landing as soon as the throttle stick is
moved beyond its switch point.
• Switch on/off of the timer for measuring the
operating time of electric motors.

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 specic 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.

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".

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

In the transmitter's delivered state, the first model

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.

On this view it can be seen that the receiver is “specific memory” associated with the default option set

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 …

… will appear for several seconds as noti cation
that a binding connection to a receiver is "not

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

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

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 memoryspecic, 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
specic, 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.
Program description - Base setup models | Winged models
83
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,

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

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.
After selection of the desired output with the selection keys of the left or right touch pad, the appropriate
value field will be framed. Briefly tap on the centre
SET key of the right touch pad. The current setting
will be displayed in inverse video. Now use the selection keys of the right touch pad to select the desired
input channel's respective transmitter output, see
page 234.
BUT CAUTION:
If, for example, "2AIL" has been specified in
the "Aileron/camber flaps" line of the »Model
type« menu (see page 105) then the transmitter will have allocated control function 2 (ailerons)
to control channels 2 & 5 for the left and right ailer-ons. The corresponding receiver inputs to be as-
signed in this case would be channels 2 & 5, refer to
the example below.
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).
Program description - Base setup models | Winged models
87
• You would like to control the rudder 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, the default rudder channel
(4), see gure bottom right.
Notes:
•
The maximum number of lines (outputs)
available corresponds to the maximum
number of servos which can be connected
to the receiver in question.
• 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.
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.
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

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.

model or check the radio connection to your model
and repeat the process afterwards.
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 Graupnermc 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.
To change the throttle servo's preset "cut-off" position, tap on the centre SET key of the right touch pad.
The current setting will be displayed in inverse video.
Now use the selection keys of the left or right touch
pad to set a value at which the motor is reliably "off".
If a combustion motor is involved, be sure the throttle servo does not perform mechanical runout, e. g.
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.
Finally, use the column at the right to specify a switch
with which you can cut off the motor directly (emergency) or which will be activated by the threshold.

• A threshold over +100 % is reached by temporarily

Auto trim–––
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.

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

model memory “of their” Graupner HoTT transmitter.
This process is commonly referred to by the English
term “binding” and can be repeated anytime. This

You can now select “6” or “8” channels using the righthand Select buttons. The procedure is concluded by
again pressing the central SET button of the righthand four-way button.
At the transmitter this selection only affects the number of control channels transferred to the external RF
module via the DATA socket. If you choose “6”, then
these are control channels 1 … 6; if you choose “8”,
these are channels 1 … 8.
Simultaneously pressing the or buttons of

As mentioned in the introduction to the “Binding receivers” section, this menu item of the mc-32 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.
Program description - Base setup models | Helicopter models
After selection of the desired output with the selection keys of the left or right touch pad, the appropriate
value fi eld will be framed. Briefl y tap on the centre
SET key of the right touch pad. The current setting
will be displayed in inverse video. Now use the selection keys of the right touch pad to select the desired
input channel’s respective transmitter output, see
page 234.
BUT CAUTION:
If you wish to operate two servos with one
control function, for example such as trans-
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.
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.
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.
... appears, the RF module of the transmitter is
inactive. Turn on the RF module and try again.
• If instead, the message ...
CAN‘T
RECEIVE
DATA
... is displayed, there is no connection to a
receiver. Switch on the receiving system of your
model or check the radio connection to your model
and repeat the process afterwards.
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:
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.
