Safety notes

Please read carefully!

We all want you to have many hours of pleasure in our mutual hobby of modelling, and safety is an important aspect of this. It is absolutely essential that you read right through these instructions and take careful note of all our safety recommendations. If you are a beginner to the world of radio-controlled model aircraft, boats and cars, we strongly advise that you seek out an experienced modeller in your field and ask him for help and advice. These instructions must be handed on to the new owner if you ever sell the transmitter.

Application

This radio control system may only be used for the purpose for which the manufacturer designed it, i.e. for operating radio-controlled models which do not carry humans. No other type of use is approved or permissible.

Safety notes

SAFETY IS NO ACCIDENT

and …

RADIO-CONTROLLED MODELS ARE NOT

PLAYTHINGS

Even small models can cause serious personal injury and damage to property if they are handled incompetently. Technical problems in electrical and mechanical systems can cause motors to rev up or burst into life unexpectedly, with the result that parts may fly off at great speed, causing considerable injury. Short-circuits of all kinds must be avoided at all times. Short-circuits can easily destroy parts of the radio control system, but even more dangerous is the acute risk of fire and explosion, depending on the circumstances and the energy content of the batteries.

The circumstances and the energy content of the batteries. Aircraft and boat propellers, helicopter rotors, open gearboxes and all other rotating parts which are driven by a motor or engine represent a constant injury hazard. Do not touch these items with any object or part of your body. Remember that a propeller spinning at high speed can easily slice off a finger! Ensure that no other object can make contact with the driven components.

Protect all electronic equipment from dust, dirt, damp, and foreign bodies. Avoid subjecting the equipment to vibration and excessive heat or cold. Radio control equipment should only be used in „normal“ ambient temperatures, i.e. within the range -15°C to +55°C. Avoid subjecting the equipment to shock and pressure.

Check the units at regular intervals for damage to cases and leads. Do not re-use any item which is damaged or has become wet, even after you have dried it out thoroughly. Use only those components and accessories which we expressly recommend. Be sure to use only genuine matching GRAUPNER connectors of the same design with contacts of the same material. Use only genuine GRAUPNER plug-in crystals on the appropriate frequency band. When deploying cables note that they must not be under tension, and should never be bent tightly or kinked, otherwise they may fracture. Avoid sharp edges which could wear through the cable insulation. Check that all connectors are pushed home firmly before using the system. When disconnecting components, pull on the connectors themselves - not on the wires.

It is not permissible to carry out any modifications to the RC system components. Avoid reverse polarity and short-circuits of all kinds, as the equipment is not protected against such errors.

Installing the receiving system and deploying the receiver aerial

In a model aircraft the receiver must be packed in soft foam and stowed behind a stout bulkhead, and in a model boat or car should be protected effectively from dust and spray.

The receiver must not make contact with the fuselage, hull or chassis at any point, otherwise motor vibration and landing shocks will be transmitted directly to it. When installing the receiving system in a model with a glowplug or petrol engine, be sure to install all the components in well protected positions so that no exhaust gas or oil residues can reach the units and get inside them. This applies above all to the ON / OFF switch, which is usually installed in the outer skin of the model. Secure the receiver in such a way that the aerial, servo leads and switch harness are not under any strain. The receiver aerial is permanently attached to the receiver. It is about 100 cm long and must not be shortened or extended. The aerial should be routed as far away as possible from electric motors, servos, metal pushrods and high-current cables. However, it is best not to deploy the aerial in an exactly straight line, but to angle it: e.g. run it straight to the tailplane, then leave the final 10 - 15 cm trailing down, as this avoids reception „blind spots“ when the model is in the air. If this is not possible we recommend that you lay out part of the aerial wire in an S-shape inside the model, close to the receiver if possible.

Safety notes

Installing the servos

Always install servos using the vibration-damping grommets supplied. The rubber grommets provide some degree of protection from mechanical shocks and severe vibration.

Installing control linkages

The basic rule is that all linkages should be installed in such a way that the pushrods move accurately, smoothly and freely. It is particularly important that all servo output arms can move to their full extent without fouling or rubbing on anything, or being obstructed mechanically at any point in their travel.It is important that you should be able to stop your motor at any time. With a glow motor this is achieved by adjusting the throttle so that the barrel closes completely when you move the throttle stick and trim to their end-points.Ensure that no metal parts are able to rub against each other, e.g. when controls are operated, when parts rotate, or when motor vibration affects the model. Metal-to-metal contact causes electrical „noise“ which can interfere with the correct working of the receiver.

Always extend the transmitter aerial fully before operating your model.

Transmitter field strength is at a minimum in an imaginary line extending straight out from the transmitter aerial. It is therefore fundamentally misguided to „point“ the transmitter aerial at the model with the idea of obtaining good reception. When several radio control systems are in use on adjacent channels, the pilots should always stand together in a loose group. Pilots who insist on standing away from the group endanger their own models as well as those of the other pilots.

Pre-flight checking

If there are several modellers at the site, check carefully with all of them that you are the only one on „your“ channel before you switch on your own transmitter.If two modellers switch on transmitters on the same channel, the result is interference to one or both models, and the usual result is at least one wrecked model.

Before you switch on the receiver, ensure that the throttle stick is at the stop / idle end-point.

Always switch on the transmitter first, and only then

the receiver.

Always switch off the receiver first, and only then

the transmitter.

If you do not keep to this sequence, i.e. if the receiver is at any time switched on when „its“ transmitter is switched off, then the receiver is wide open to signals from other transmitters and any interference, and may respond. The model could then carry out uncontrolled movements, which could easily result in personal injury or damage to property. The servos may run to their end-stops and damage the gearbox, linkage, control surface etc. Please take particular care if your model is fitted with a mechanical gyro: Before you switch your receiver off, disconnect the power supply to ensure that the motor cannot run up to high speed accidentally. The gyro can generate such a high voltage as it runs down that the receiver picks up apparently valid throttle commands, and the motor could respond by unexpectedly bursting into life.

Range checking

Before every session check that the system works properly in every respect, and has adequate range. This means checking that all the control surfaces respond

correctly and in the appropriate direction to the transmitter commands at a suitable ground range. Repeat this check with the motor running, while a friend holds the model securely for you.

Operating your model aircraft, helicopter, boat or car

Never fly directly over spectators or other pilots, and take care at all times not to endanger people or animals. Keep well clear of high-tension overhead cables. Never operate your model boat close to locks and full-size vessels. Model cars should never be run on public streets or motorways, footpaths, public squares etc.

Checking the transmitter and receiver batteries

It is essential to stop using the radio control system and recharge the batteries well before they are completely discharged. In the case of the transmitter this means

- at the very latest - when the message „Battery must be charged“ appears on the screen, and you hear an audible warning signal. It is vital to check the state of the receiver battery at regular intervals. When the battery is almost flat you may notice the servos running more slowly, but it is by no means safe to keep flying or running your model until this happens. Always replace or recharge the batteries in good time. Keep to the battery manufacturer’s instructions and don’t leave the batteries on charge for longer than stated. Do not leave batteries on charge unsupervised. Never attempt to recharge dry cells, as they may explode. Rechargeable batteries should always be recharged before every session. When charging batteries it is important to avoid short-circuits. Do this by first connecting the charge lead banana plugs to the charger, taking care to maintain correct polarity. Only then connect the charge lead to the transmitter or receiver battery.

4 Safety notes

Safety notes

Disconnect all batteries and remove them from your model if you know you will not be using it in the near future.

Capacity and operating times

This rule applies to all forms of electrical power source: battery capacity is reduced every time you charge it. At low temperatures capacity is greatly reduced, i.e. operating times are shorter in cold conditions. Frequent charging, and / or the use of maintenance programs, tends to cause a gradual reduction in battery capacity. We recommend that you check the capacity of all your rechargeable batteries at least every six months, and replace them if their performance has fallen off significantly. Use only genuine GRAUPNER rechargeable batteries!

Suppressing electric motors

All conventional electric motors produce sparks between commutator and brushes to a greater or lesser extent depending on the motor type; the sparking generates serious interference to the radio control system. In electric-powered models every motor must therefore be effectively suppressed. Suppressor filters effectively eliminate such interference, and should always be fitted. Please read the notes and recommendations supplied by the motor manufacturer. Refer to the main GRAUPNER FS catalogue for more information on suppressor filters.

Servo suppressor filter for extension leads

Order No. 1040 Servo suppressor filters are required if you are obliged to use long servo extension leads, as they eliminate the danger of de-tuning the receiver. The filter is connected directly to the receiver input.

In very difficult cases a second filter can be used, positioned close to the servo.

Using electronic speed controllers

Electronic speed controllers must be chosen to suit the size of electric motor which they will control. There is always a danger of overloading and possibly damaging the speed controller, but you can avoid this by ensuring that the controller’s current-handling capacity is at least half the motor’s maximum stall current. Particular care is called for if you are using a „hot“ (i.e. upgrade) motor, as any low-turn motor (small number of turns on the winding) can draw many times its nominal current when stalled, and the high current will wreck the speed controller.

Electrical ignition systems

Ignition systems for internal combustion engines can also produce interference which has an adverse effect on the working of the radio control system. Electrical ignition systems should always be powered by a separate battery - not the receiver battery. Be sure to use effectively suppressed spark plugs and plug caps, and shielded ignition leads. Keep the receiving system an adequate distance away from the ignition system.

Caution:

Radio control systems may only be operated on the frequency bands and spot frequencies approved in each EU country. You will find information on frequencies in the section entitled „Approved operating frequencies“. It is prohibited to operate radio control systems on any other frequency, and such misuse will be punished by the relevant authorities.

Static charges

Lightning causes magnetic shock waves which can interfere with the operation of a radio control transmitter even if the thunderstorm actually occurs several kilometres away. For this reason cease flying operations immediately when you notice an electrical storm approaching.

Static charges through the transmitter aerial can be life-threatening!

Care and maintenance

Don’t use cleaning agents, petrol, water or other solvents to clean this equipment. If the case, the aerial etc. gets dirty, simply wipe the surfaces clean with a soft dry cloth.

Liability exclusion / Compensation

As manufacturers, we at GRAUPNER are not in a position to influence the way you install, operate and maintain the radio control system components. For this reason we are obliged to refute all liability for loss, damage or costs which are incurred due to the incompetent or incorrect use and operation of our products, or which are connected with such operation in any way.

Unless otherwise prescribed by law, the obligation of the GRAUPNER company to pay compensation is limited to the invoice value of that quantity of GRAUPNER products which was immediately and directly involved in the event in which the damage occurred. This does not apply if GRAUPNER is found to be subject to unlimited liability according to binding legal regulation on account of deliberate or gross negligence.

Description of radio control system 7

Charging the transmitter battery

The rechargeable transmitter battery can be charged via the charge socket fitted to the side of the case. The transmitter must be switched „OFF“ for the whole period of the charge process. Never switch on the transmitter when it is still connected to the charger; even a very brief interruption in the charge process can cause the charge voltage to rise to the point where the transmitter is immediately damaged by the excess voltage. Alternatively the interruption may trigger a new charge cycle, which means that the battery will possibly be severely overcharged.

For this reason check carefully that all connectors are secure, and making really good contact. Interruptions due to an intermittent contact, no matter how brief, inevitably cause the charger to malfunction.

Polarity of the mx-12 charge socket

Commercially available battery charge leads produced by other manufacturers are often made up with the opposite polarity. For this reason use genuine GRAUPNER charge leads exclusively.

Notes on recharging transmitter batteries using an automatic charger

· Observe the recommendations provided by the charger manufacturer and the battery manufactu rer at all times.

· Carry out a series of test charges to ensure that the automatic charge termination circuit works correctly with your battery. This applies in parti cular if you are using an automatic charger desig ned for NiCd batteries to recharge the standard NiMH battery. You may need to adjust the Delta Peak trigger voltage, if your charger provides this option.

· The charge current must be set using the charger’s „manual charge current select“ facility, to ensure that the maximum charge current never exceeds 1.5 A. Never allow the charger to set the charge current automatically.

· Do not discharge the battery or carry out a battery maintenance program via the integral charge socket. The charge socket is not suitable for this application.

· If you intend to charge the transmitter battery at a current higher than 1.5 A, the battery must be removed beforehand, otherwise the transmitter could be damaged through overheating.

Throttle Stick

The initial setting for the throttle stick is ratched type. If you don`t like this feeling, please follow the following instruction to change it. You will be required a posidrive screwdriver and a pair of tweezers;

1. Remove the model from back of the transmitter, by squeezing the lugs and pulling it out.

2. Remove the battery cover by pushing it inwards and downwards. Remove the battery.

3. Remove 4 screws from the rear 4 corners. Remove 2 screws, 1 from either side of the rear antenna base.

4. Carefully separate the 2 halves of the transmitter, starting at the base.

5. Unplug the 2 multi pin connectors for ease of access.

6. The left side of left stick unit has a black plastic lever and spring, which provide the centring action - move the stick if you are in doubt. Using the tweezers, remove the spring.

7. Slide the lever towards the center of the transmitter in order to remove ir from its pivot (move the stick to clear it if necessary).

8. Reverse the above process to fit the lever and spring to the right-hand assembly (note; the pivot is at the top of the right-hand stick assembly).

10 Transmitter description

Direct servo control (DSC)

9. The left side of the right-hand assembly has a metal strip which provides the ratched friction action. This is held in place by two screws. Undo the screws and transfer the metal strip to the left-hand assembly.

10. The mechanical conversion is now completed; check the stick actions are as required and reassemble the transmitter by reversing the above process, not for getting to plug in the multipin connectors.

Frequency notes

The mx-12 can transmit in either Pulse Code Modulation (PCM) or Pulse Position Modulation (PPM, commonly referred to as FM):

Be certain to observe the following guidelines:

Do not operate your transmitter when another transmitter is using the dame frequency, regardless of whether the second transmitter is PCM, PPM (FM) or AM. You can never operate two transmitters on the same frequency simultaneously without causinf interference.

For proper DSC hook-up and operation:

1. Leave the transmitter power switch in the OFF posi tion. The transmitter will not transmit any radio fre quency (RF) in this position.

2. Plug the (supplied) DSC cord into the DSC port in the rear of the transmitter.

3. The encoder section of the transmitter will now be operational and the LCD display will be lit.

4. Plug the other end of the DSC Cord into the receiver charge receptacle. Turn the switch harness to the ON position.

Note: When you install the charging jack, be sure to hook the charging jack receptable securely into the switch harness charge cord.

Why you should use the DSC function:

1. The DSC enables you to check the control surfaces of your aircraft without drawing the fully operational 200mAh from your transmitter battery pack. Instead, you will only draw approximately 70mAh when using the DSC function.

2. The DSC function allows you to make final adjust ments to your airplane without transmitting any radio signals. Therefore, if another pilot is flying on your frequency, you can still adjust your aircraft and not interfere with the other pilot`s aircraft.

Note: This function is for bench-checking your airplane only.

Installation requirements

It is extremely important that your radio system be correctly installed in your model. Here a few suggestions installing your GRAUPNER equipment:

1. Wrap the receiver in protective foam rubber that is no less than 3/8 inch thick. Secure the foam to the receiver with #64 rubber bands. This protects the receiver in the event of a crash or a very hard landing.

2. The servos should be mounted using rubber grom mets and brass eyelets to isolate them from vibrati on. Do not over-tighten the mounting screws; this will negate the vibration absorption effect of the rubber grommets. The following diagram will assist you in properly mounting your servo. The brass eyelet are pushed from the bottom up in the rubber grommets. When the servo screw is tightened securely, it provi des the proper security as well as the proper vibrati on isolation for your servo.

3. The servos must be able to move freely over their entire range of travel. Make sure that the control linkages do not bind or impede the movement of any of the servos.

4. Mount all switches away from the engine exhaust and away from any high vibration areas. Make sure the switch operates freely and is able to operate over its full travel.

5. Mount the receiver antenna firmly to the airplane to ensure that it will not become entangled on the propeller or control surfaces.

To increase the contrast (darken the screen), simply turn the power switch ON and press the SEL and DATA + keys simultaneously. To decrease the contrast (lighten the screen), press the SEL and DATA - keys simultaneously.

Advanced Digital Trim (A.D.T.)

The mx-12 digital trims feature the Direct Access display function. While at the Normal display screen, if a trim lever is moved, the screen will automatically change to display the graphic position for the trim being adjusted. The mx-12 Aileron, Elevator, Throttle and Rudder trim levers feature an audible center trim beep. This is helpful in determining the trim levers center position during flight. Please also note that unlike conventional mechanical trim levers, when the mx-12 transmitter is in the off position, no changes can be made to the trim values during transportation.

Exponential Value

Dual Rate Value

D/R POSITION

Dual rates are available for the aileron, elevator and rudder channels of yor R/C aircraft. The combined Dual Rate Function is discussed at page XX. Dual rates may be defined as the ability to vary the travel or throw rate of a servo from a switch. Due to the differing travel rates, you will find that the sensitivity of the control either increases or decreases accordingly. A higher rate, or travel, yields a higher overall sensitivity. You may find it easier to think of the Dual-Rate function as double-rates or half-rates. The amount of travel is adjustable from 0-125% in 1% increments. The factory setting, or default value, for both the 0 and 1 switch positions is 100%. Exponential reduces the sensitivity in the middle portion of stick movement, while still allowing full travel at the end of the stick movement. The end result (travel) remains the same, although exponential changes the rate at which it achieves this travel. The adjustable range is from 0-100%. Zero percent (0%) is linear stick control, meaning the response rate is equal throughout the stick control. 100% is full exponential. The larger the exponential value, the less servo action or sensitivity you will notice around the neutral setting. Either switch position may be selected as the low or high rate by placing the switch in the desired position and adjusting the value accordingly.

Programmable Mixing (1~4)

The mx-12 offers four programmable mixes to be used for any number of different purposes. This function allows mixing any one channel to any other channel. This mix can remain on at all times or be switched on and off in flight using a number of different switches. Mix numbers 1-3 are of the standard variety, in that the digital trim for the master channel only affect the master channel, and not the slave channel. Mix number 4 is of the “Trim Include“ variety. This mix is used any time the mix requires the slave channels trim position to be varied when the master channels digital trim position is varied. An example for this type of mix would be when dual elevator or dual aileron servos are used and connected to two separate channels of the system, rather than using a single channel with a Y-harness. Each channel of this radio is identified by an abbreviated name. The chart below indicates the channel and its corresponding abbreviation. The channel name apperaing first is known as the “master channel“ or the channel to which you want to mix. The second number is known as the “slave channel“ or the channel that is being mixed into the master channel. For example, AILRUD would indicate aileron-to-rudder mixing. Each time the aileron stick is moved, the aileron will deflect, and the rudder will automatically move in the

direction and to the value input. Mixing is proportional, so small inputs of the master channel will produce small outputs of the slave channel. Each programmable mix has a mixing “offset“. The purpose of the mixing offset is to re-define the neutral position of the slave channel.

Fail Safe

The Fail Safe/Hold function is available only when you use the mx-12 transmitter in PCM modulations. This function is designed to help minimize damage to your aircraft during a loss of signal to the receiver. The servos either assume the fail-safe presets or hold their last good signal position. As noted earlier, if you are in the PPM modulation, the Fail-Safe/Hold function is not applicable. Therefore, the Fail-Safe/Hold function will not appear on your LCD screen menu while in the PPM mode. Refer to the Modulation Selection section for more information pertaining to the broadcast signal of your mx-12 transmitter.

(Graupner style, most popular)

3 Servo/90° CCPM

1.) One servo (Standard Mechanical Miying) The most common form of Swashplate Mixing. This type uses each of the three servo to move the swashplate individually for pitch, Aileron and Eleva tor changes. If one servo (NORM) is selected in the System Mode (Factory Default), the Swashplate Type Function will not appear on the LCD screen in this section.

2.) Two servo (180-degrees) Two servos are used to move the swashplate, and are spaced at 180 degrees apart. This is not a very common control system configuration.

3.) Three servo (120-degrees) Three servos are used to move the swashplate , and are spaced at 120 degrees apart. This is the most common form of CCPM, and is found in Graupner and other brands of Helicopters.

4.) Three servo (90-degrees) Three servos are used to move the swashplate, and are spaced at 90 degrees apart. This is also not a very common control system configuration.

Throttle Curves

The mx-12 offers two (2) separate throttle curves with five adjustable points per curve. This function allows you to customize the throttle curve and pitch curve together to maximize engine performance at a particular pitch setting. Once the throttle curves are established, each can be activated in flight using the two (2) position flight mode switch. The flight mode switch offers two selectable ranges: Normal and Stunt. The Normal position should be used as the hover throttle curve. The Stunt position should be used for aerobatic maneuvers and forward flight. Note: The throttle trim and hovering throttle levers are only operable when the flight mode switch is in the normal position. Thus, in normal function it will have no effect. Also, adjusting the hovering throttle lever and throttle trim has no effect on the input values of the throttle curve. Each of the five points of the throttle curve are independently adjustable from 0-100%. These five points correspond to the position of the throttle stick. The illustration below shows the normal throttle curve setting for the dead slow position with throttle trim at default.

Revolution Mixing (Non-heading lock Gyros only), Programmable Mixing (1~2)

Revolution Mixing (Non-heading lock Gyros only)

The Revolution Mixing function mixes tail rotor with the Throttle and Pitch Curve functions to counteract torque from the main rotor blades. When set up correctly, the helicopter should climb and descend without a tendency to yaw in either direction. Because torque reaction varies with different power settings, it is necessary to vary the tail rotor pitch at the same time. The mx-12 offers two separate revolution mixing programs, with independent up and down mixing for each - one for Flight mode position Normal and the other for Stunt. The up mixing adjusts the tail rotor compensation for the mid to high throttle setting and the down mixing adjusts the tail rotor compensation for the mid to low throttle setting.

Setting Up Revolution Mixing (non-heading lock, gyros only)

Set up the helicopter so that it will hover with the tail rotor trim entered. Establish the helicopter into a stable hover, then steadily increase the throttle to initiate a steady climb. The body of the helicopter will move in the opposite direction to the main rotor rotation. Increase the U, Up, setting until the helicopter climbs with no tendency to turn. At a safe altitude, close the throttle; the helicopter will same direction as the main rotor rotation. Increase the D, or Down, mix until the helicopter descends with no tendency to turn. Throttle stick movements should be slow, and the initial accerlation and deceleration swings should be ignored. The Accerlation Mixing function is provided to compensate for the main rotor accerlation (and decerlation) torque.

Programmable Mixing (1~2)

The mx-12 offers two programmable mixes to be used for any number of different purposes. This function allows mixing any one channel to any other channel. This mix can remain on at all times or be switched on and off in flight using a number or different switches. Mix number 1 is of the standard variety, in that the digital trim for the master channel only affect the master channel, and not the slave channel. Mix number 2 is of the “Trim include“ variety. This mix is used any time the mix requires the slave channels trim position to be varied when the master channels digital trim position is varied. Each channel of this radio is identified by an abbreviated name. The chart below indicates the channel ant its corresponding abbreviation. The channel name appearing first is known as the “master channel“ or the channel to which you want to mix. The second number is known as the “slave channel“ or the channel that is beeing mixed into the master-channel. For example, AILRUD would indicate aileron-to-rudder mixing. Each time the aileron stick is moved, the aileron will deflect, and the rudder will automatically move in the direction and to the value input. Mixing is proportional, so small inputs of the master channel will produce small outputs of the slave channel. Each programmable mix has a mixing “offset“. The purpose of the mixing offset is to redefine the neutral position of the slave channel.

Fail Safe

The Fail Safe Function is available only when you use the mx-12 transmitter in PCM modulations. This function is designed to help minimize damage to your aircraft during a loss of signal to the receiver. The servos either assume the Fail Safe presets or hold their last good signal position. As noted earlier, if you are in the PPM modulation, the Fail Safe Function is not applicable. Therefore, the Fail Safe Function will not appear on your LCD screen menu while in the PPM mode. Refer to the Modulation Selection section for more information pertaining to the

broadcast signal of you mx-12 transmitter. Note: The throttle Fail Safe position is defaulted to the idle position for added safety.

Trainer Function

The mx-12 offers a programmable trainer function with three trainer options:

Normal mode: - In this mode the transmitter acts as a conventional buddy-box system. The transmitter can be used as a slave or as a master: however in this mode, the reversing switches and trims must be adjusted so the slave transmitter matches the master transmitter. In normal mode, when the trainer switch is activated, the student has control of all functions and switches.

Pilot Link: - When Pilot Link mode is used with the master transmitte, it allows the slave transmitter to be adjusted to factory defaults. The slave transmitter can simply be programmed in a model memory not being used and reset to factory defaults, thus preventing the need to synchronize the trims and reversing switches on the slave transmitter. Also when Pilot Link is used, the student only has control of the 4 basic channels (throttle, aileron, elevator, rudder) while the trainer (master) retains control of all other functions like gear, dual rate, programmed mixes, etc. This allows a pilot to have a test flight on a more complex airplane without having to remember complex switch positions.

Pilot Link + Slave: - This mode is used only wehen the mx-12 is being used as a slave transmitter and the other Master transmitter has a Pilot Link program active. By selecting Pilot Link + Slave the transmitter is automatically in the correct programming mode to work as a slave in conjunction with another Pilot Link equipped transmitter.

Normal

This is used with aircraft with one servo operating both ailerons. This mode is the default setting and is active when the Flapneron, Elevon and V-Tail modes are off.

Flaperon

This mode is used when two servos are used to operated the ailerons. Flaperons allow each aileron to be independently adjusted. In addition, they can be programmed to move in the same direction for use as flaps or spoilers.

Elevon

This mode is used for some types of delta wing aircraft where the control surfaces function as both ailerons and elevators.

V-Tail

Used for V-tailed airplanes Note: Some function will be unavailable when certain functions are active. With Flaperon active, Elevon will be unavailable. With Elevon active, both Flaperon and V-Tail will be unavailable. Finally, with V-Tail active, Elevon will be unavai lable.

Flaperon Wing Type Selection

Flaperons allow you to use the existing ailerons as flaps. The ailerons can be raised or lowered in unisonas flaps, yet still remain fully operational as the ailerons of your RC airplane.

GETTING STARTED

Thank you for purchasing the Graupner HoTT 2.4 System Please read through this entire manual before you attempt the installation and usage of your Graupner HoTT 2.4 System!

These operating instructions are part of this product. They contains important notes to the operation and handling. Please take this into consideration when you pass on the product to third parties. Neglect of the operating instructions and the safety instructions lead to expiring the warranty. Graupner constantly work on the advancement of all remote control systems; changes of the scope of delivery in form, technology and equipment we must reserve ourselves therefore. Please have understanding for the fact that from data and illustrations of this operating instructions no requirements can be derived.

Please keep these instructions for further reference!

1. GENERAL NOTE

When switching on or adjusting the radio control system it is essential to keep the transmitter aerial at least 15 cm away from the receiver aerials at all times. If the transmitter aerial is too close to the receiver aerials, the receiver will be overloaded, causing the red LED on the receiver to light up. The transmitter responds by emitting a beep once every second; the red LED also goes out. The radio control system is now in Fail-Safe mode. If this should occur, simply increase the distance between the aerials until the audible warning signal ceases, and the red LED on the transmitter lights up again; at the same time the red LED on the receiver should go out.

2. FUNCTIONS

2.1. Binding

When you wish to use the Graupner HoTT 2.4 GHz receiver with a particular transmitter, the ﬁ rst step must always be to “bind” the unit to “its” Graupner HoTT 2.4 GHz RF module (transmitter). This “binding” procedure only needs to be carried out once for each combination of receiver and RF module. The units supplied in the set are already bound to each other at the factory, i.e. the binding procedure described in the following section only needs to be carried out when you wish to use an additional receiver. However, it can also be repeated at any time if required, e.g. after changing transmitters. When binding is required, this is the procedure:

• Switch the transmitter and receiver on.

• Locate the BIND / RANGE button on the back of the transmitter, and hold it pressed in while you press and hold the SET button on the receiver. Both LEDs on the back of the transmitter now glow constantly, and the red LED on the receiver ﬂ ashes.

• Under normal circumstances the ﬂ ashing red LED on the receiver will cease to ﬂ ash and switch to a constant green within about ten seconds. This indicates that the binding process is complete. You can now release both buttons, and your transmitter / receiver combination is ready for use.

• However, if the red LED on the receiver continues to ﬂ ash for longer than ten seconds, then the binding process has failed. If this should occur, repeat the whole procedure.

2.1.1.Binding“ multiple receivers in one model

If required, it is also possible to bind multiple receivers to the transmitter for a particular model. The ﬁ rst step is to bind each receiver individually using the procedure already described. When the system is in use, the receiver which is switched on ﬁ rst is the Master receiver. Any telemetry sensors installed in the model must be connected to this unit, as only the Master receiver transmits sensor data using the downlink channel. The second and all further receivers operate in parallel with the Master receiver but in Slave mode, with the downlink channel switched off. The control functions can also be distributed amongst multiple receivers; this is carried out using the Channel Mapping function of the SMART-BOX (Order No. 33700). In the same way it is possible to assign one control function to multiple receiver outputs; a typical example would be the use of two servos for each aileron instead of only one, etc.

Getting Started Graupner HoTT 2.4 01

2.2. Range checking

The method of checking the effective range of the Graupner HoTT 2.4 GHz system is described below. We recommend that you ask a friend to help you with this procedure. After binding the receiver to your transmitter, switch the transmitter and the receiver on, and wait until the green LED on the receiver lights up.

• Install the bound receiver in the model in its ﬁ nal intended position.

• Switch the RC system on, so that you can observe the movement of the servos.

• Set up the model on a ﬂ at surface (pavement, closely mown grass or earth), and ensure that the receiver aerials are located at least ﬁ fteen cm above the ground. This may require a support for the model.

• Hold the transmitter at hip-height, away from your body, but do not point the aerial directly at the model; instead turn and / or angle the aerial tip so that it stands vertical, and keep it there for the duration of the range check.

• Locate the BIND / RANGE button on the back of the transmitter, and press it to initiate range-check mode. Hold the button pressed in until the transmitter starts to beep at a regular rhythm; the red and green LEDs adjacent to the BIND / RANGE button now ﬂ ash alternately.

• Walk away from the model, operating the transmitter sticks constantly. If you detect an interruption in the link within a range of about ﬁ fty metres, stand still and attempt to reproduce it.

• If the model is ﬁ tted with a motor, switch it on in order to check whether the power system is gene- rating interference.

• Continue to walk away from the model until you reach the point where perfect control is no longer possible.

• Now press the BIND / RANGE button on the transmitter once more; this terminates range-check mode manually, and the model should respond normally to control commands. If this does not occur with 100% reliability, the system should not be used. Contact your local Service Department of Graupner GmbH & Co. KG.

• Range-check mode is usually terminated manually when the user presses the BIND / RANGE but ton, but it terminates automatically after about ninety seconds in any case. The red LED now glows constantly again, while the green LED either glows constantly or ﬂ ashes continuously, according to the Country setting.

• We recommend that you check effective radio range before every ﬂ ight. While you are carrying out the check, simulate all the servo movements which will take place when the model is in ﬂ ight. The ground range must always be at least ﬁ fty metres in order to ensure safe, reliable model con- trol.

Note:

Range-check mode is usually terminated manually when the user presses the BIND / RANGE button, but it terminates automatically after about ninety seconds in any case.

CAUTION:

During normal operations (i. e. when controlling a model) never press and hold the programming button on the transmitter module!

2.3. Fail-Safe function

In its default state (as delivered) the receiver is set to “Hold” mode, i.e. if a fail-safe situation occurs, all the servos connected to it maintain the last position detected as valid. In this mode the red LED on the receiver lights up when interference occurs, and the red LED on the transmitter goes out. The transmitter also starts beeping about once per second as an audible warning. You can exploit the safety potential of the fail-safe option by at least programming the throttle channel to respond to a fail-safe situation: the throttle channel of an engine-powered model should be set to idle, the throttle channel of an electric-powered model to “stop”, and the throttle channel of a model helicopter to “Hold”. If interference should occur, these settings will help prevent the model ﬂ ying out of control, possibly causing personal injury or property damage.

IMPORTANT:

The two functions “Binding” and “Range check” described above can be used regardless of the method you last employed to program the transmitter, i.e. using the programming button or the SMART-BOX; neither of these two options causes signiﬁ cant changes to the settings saved in the receiver. However,

02 Getting Started Graupner HoTT 2.4

if you call up the Fail-Safe function using the programming button as described below, this resets ALL the settings of the SMART-BOX at the Fail-Safe screen (RX FAIL SAFE) - and this includes the settings available through the facilities of the programming button. At the same time the Country setting will revert to Universal if you have previously selected “France” using the programming button - see below under “2.4”. You MUST therefore select the Country setting again if necessary. For this reason, wherever possible it is always best to maintain your programmed settings using the SMART-BOX.

Switch your receiving system on. Locate the BIND / RANGE button on the back of the transmitter, and hold it pressed in while you switch the transmitter on. Release the button again once it is switched on. You can now call up the desired Fail-Safe mode (Fail-Safe on / off, Hold, or Standard) by cycling through the modes with a brief press of the BIND / RANGE button:

• Fail-Safe mode: when you press the BIND / RANGE button, the transmitter beeps once; the red and green LEDs glow constantly. It is now possible to program positions to which the servos will move in a Fail-Safe situation; this occurs after a “Hold” period of 0.75 seconds: move the corresponding transmitter controls (sticks, rotary knobs, INC / DEC buttons etc.) to the desired Fail-Safe positions SIMULTANEOUSLY, then hold the BIND / RANGE button pressed in for three to four seconds. When you release the button, both the red and green LEDs should light up constantly, and the transmitter should not emit an au dible signal: the transmitter now reverts to Control mode. If this does not occur, repeat the procedu re.

• Hold mode (recommended for model helicopters): when you press the BIND / RANGE button, the transmitter beeps twice; the red LED lights up constantly, and the green LED goes out (factory default setting). If interference occurs, all servos programmed to “Hold” remain at the last position detected by the receiver as correct; this situation is maintained until such time as the receiver picks up a new, valid control signal. You can save your selection by holding the BIND / RANGE button pressed in for three to four se conds. When you release the button, both the red and green LEDs should light up constantly, and the transmitter should not emit an audible signal: the transmitter now reverts to Control mode. If this does not occur, repeat the procedure.

• Fail-Safe OFF: when you press the BIND / RANGE button, the transmitter beeps three times; the green LED glows constantly, the red LED goes out. You can save your selection by holding the BIND / RANGE button pressed in for three to four se conds. When you release the button, both the red and green LEDs should light up constantly, and the transmitter should not emit an audible signal: the transmitter now reverts to Control mode. If this does not occur, repeat the procedure.

• Standard mode (suitable for ﬁ xed-wing model aircraft only): when you press the BIND / RAN- GE button, the transmitter beeps four times; both LEDs are off. In this mode the throttle servo (channel 1) moves to the Fail-Safe position, i.e. the position you have programmed for a Fail-Safe situation, while all the other channels remain at “Hold”. Move the throttle stick to the desired position, then hold the BIND / RANGE button pressed in for three to four seconds. When you release the button, both the red and green LEDs should light up constantly, and the transmitter should not emit an audible signal: the transmitter now reverts to Control mode. If this does not occur, repeat the procedure.

2.4. Country setting

The Country setting is present in order to cater for various directives (FCC, ETSI, IC etc.). The HoTT

2.4 radio system features a restricted frequency band for France. If you wish to use the RC system in France, the country setting on the transmitter must be set to “France” mode, as described. It is essenti- al not to use the Universal/EUROPE mode. If you select the “France” setting on your transmitter, you MUST select it again every time you alter the Fail-Safe settings using the programming button. To select a Country setting, you must ﬁ rst switch the transmitter off, then insert the (FRANCE / GE- NERAL) programming plug (supplied) in the DATA socket on the back of the transmitter. Switch the transmitter on: you can now toggle between the “GENERAL” and “France” settings by brieﬂ y pressing the BIND / RANGE button, always starting with the current setting.

• GENERAL/EUROPE: the transmitter beeps once when you press the BIND / RANGE button, and Getting Started Graupner HoTT 2.4 03

the green LED lights up constantly. Default setting: approved for use in all countries with the exception of France.

• France: the transmitter beeps twice when you press the BIND / RANGE button, and the green LED ﬂ ashes continuously.

• Once you have selected the Country setting, save it in the transmitter by holding the BIND / RANGE button pressed in for about three seconds. When you release the button, the transmitter emits a brief conﬁ rmation tune, and the beeps cease.

• Switch the transmitter off, and remove the programming plug. Do not under any circumstances use the radio control system with the programming plug inserted!

• If you subsequently wish to check the current Country setting for the transmitter, observe the green LED on the back of the transmitter when it is switched on:

green LED glowing constantly = “GENERAL” green LED ﬂ ashing constantly = “France”

2.5. Low voltage warning

If the transmitter voltage falls below 8.0 V, the RF module generates an audible low voltage warning in the form of a steady series of beeps at intervals of around one second. This occurs independently of the transmitter software.

2.6. Range warning

If the receiver signal in the down-link channel becomes too weak, the transmitter always generates an audible range warning in the form of a beep emitted about once per second. Since the transmitter’s output is much higher than that of the receiver, you will still maintain full control of the model, but in the interests of safety you should ﬂ y the model back towards you until the warning signal ceases again. If the audible range warning signal does not cease when you reduce the distance, then the transmitter or receiver low voltage or temperature warning is active! In this case you must land the model and cease operations without delay.

2.7. Firmware update or SMART-BOX connection

The SMART-BOX is connected to the DATA socket on the back of the transmitter. Firmware updates for the transmitter RF module can be transferred via the DATA or telemetry interface in conjunction with a PC running Windows XP, Vista or 7. For this you also require the USB interface, Order No. 7168.6, and the adapter lead, Order No. 7168.6A, which are available separately. The programs and ﬁ les required for this are available from www.graupner.de in the Download area for the corresponding products. See also chapter 4.1.

Programming socket

3.1 Connections

Plug the servos into the row of sockets on the right-hand end of the receiver. The connector system is polarised; note the small chamfer on one edge. Never use force - the plugs should engage easily and fully. The socket polarity is also marked on the case: brown wire (-), red (+) and orange (signal). The servo sockets of the Graupner-HoTT 2.4 receiver are numbered. The socket marked “- +/B” is intended for the battery. If necessary, a servo can be connected to this socket in parallel with the power supply; a Y-lead (Order No. 3936.11) is required for this.

04 Getting Started Graupner HoTT 2.4

It is also possible to program the highest channel for the sum signal using the SMART-BOX (Order No.

33700). This is important for certain optional devices which require this signal.

Power supply for receiver 33506, 33508, 33512

When using High Power servos, connect the receiver power supply/s preferably to the vertical ports of the receiver. If necessary, the servos can be connected to this sockets in parallel with the power supply; a Y-lead (Order No. 3936.11) is required for this. The lower sockets (33508 and 33512) should not be used, because an increased voltage drop occurs. When using a dual power supply, use the sockets on the outside: Receiver 33506/33508 (GR-12/GR-16): Channel 1 and 6 (or 2 and 5) Receiver 33512 (GR-24): Channel 11 and 12

The socket marked “T” - telemetry interface - on the left-hand end of the receiver is intended for the optional telemetry sensors. This socket is also used for loading ﬁ rmware updates in conjunction with the USB interface. This socket is also polarised; note the small chamfer on one edge. Never use force - the plugs should engage easily and fully. The socket polarity is also marked on the case: brown wire (-), red (+) and orange (T).

3.2. Low voltage warning

If the receiver voltage falls below 3.8 V, the transmitter’s RF module generates a low voltage warning in the form of a “general alarm sound”: a steady beeping at intervals of about one second.

3.3. Temperature warning

If the receiver temperature falls below -10° C or exceeds +70° C, the transmitter’s RF module generates a temperature warning in the form of a “general alarm sound”: a steady beeping at intervals of about one second.

3.4. Firmware updates

Firmware updates for the receiver can be transferred via the programming socketvia the programming socket on the side of the unit, in conjunction with a PC running Windows XP, Vista or 7. For this you also require the USB interface, Order No. 7168.6, and the adapter lead, Order No. 7168.6A, which are available separately. The programs and ﬁ les required for this are available from www.graupner.de in the Download area for the corresponding products. See also chapter 4.2.

4.3. Update procedure

Ensure that the adapter lead is conﬁ gured as shown in the illustrations, and is connected correctly to the transmitter or receiver.

Start the Graupner Firmware Update Utility.

Connect the adapter lead to the DATA socket on the back of the transmitter, as shown in the illustration. This socket is also polarised; note the small chamfer on one edge. Never use force - the plug should engage easily and fully. The socket polarity is also marked on the case: the black wire (-) must be at the bottom, the white wire (S) at the top.

Connect the adapter lead to the socket on the left-hand end of the receiver, as shown in the illustration. This socket is also polarised; note the small chamfer on one edge. Never use force - the plug should engage easily and fully. The black wire (-) must be at the front, the white wire (T) at the back.

Under [COM Port Setup] select the correct COM port, i.e. the one to which the USB lead is connected. If you are not sure of this, press the button „Search“ and select in the pop-up window „Silicon Labs CP210x USB to UART Bridge“ and press „OK“.

Under [Interface Type] click on Signal 2:Vcc:Gnd. Now click on the “Browse” button and select the folder containing the previously loaded ﬁ rmware ﬁ le ending in *.bin. If everything is correct, the ﬁ le will appear in the corresponding window. The ﬁ rmware ﬁ les are encoded in product-speciﬁ c form, i.e. if you accidentally select a ﬁ le which does

06 Getting Started Graupner HoTT 2.4

not match the product (e.g. transmitter update ﬁ le instead of receiver ﬁ le), then the pop-up window “Pro- duct code error” will appear, and you will not be able to start the update procedure. Press the “Program” button in the software. Transmitter: press the BIND / RANGE button, and switch the transmitter on while you hold it pressed in. Receiver: press the SET button, and switch the receiver on while you hold it pressed in.

After a few seconds the Status screen displays the message “Found target device…”; you can now release the button, and the ﬁ rmware update process commences.

If the device is not recognised, if the pop-up window “Target device ID not found” appears, or if the process fails before 100% is reached, you must restart the update procedure. Repeat all the steps as described above.

The Status display and the Progress bar show the progress of the ﬁ rmware update. The update is completed when the mes- sage “Complete…100%” or “Complete!!” appears.

During the update process both LEDs on the transmitter glow constantly. When it is complete, the red LED goes out and you will hear a brief conﬁ rmation melody. Both LEDs on the receiver also light up; when the process is complete, the green LED goes out, and the red LED starts ﬂ ashing.

Switch your transmitter / receiver off, and disconnect the adapter lead.

Caution: after completing an update process, you must initialise the device before using it, i.e. reset it to the factory default values,.

Initialisation:

Transmitter: To initialise the system, i.e. to reset it to the factory default settings, locate the BIND / RANGE button on the back of the transmitter, hold it pressed in while you switch the transmitter on, then release the BIND / RANGE button again. Receiver: To initialise the system, i.e. to reset it to the factory default settings, locate the BIND / RANGE button on the back of the transmitter, hold it pressed in while you switch the transmitter on, then release the BIND / RANGE button again. Now immediately press and hold the SET button on the receiver, switch it on, and release the SET button again. After about two or three seconds the green LED on the receiver lights up to conﬁ rm that your radio control system has been re-initialised.

Please note:

The initialisation procedure erases ALL the settings you have entered. Where necessary, you will need to program your preferred settings again.

When initialisation is complete, the transmitter will be in Fail-Safe set-up mode. You can therefore immediately continue by programming your fail-safe settings. If you previously set your transmitter’s Country setting to “France” mode, you must also re-enter the Country setting.

Please refer to the appropriate section in your RC system instructions for the procedure.

Any settings you have entered using the SMART-BOX are also lost when you initialise the receiver. If you carry out a receiver ﬁ rmware update, you will need to re-enter these settings.
