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 push-rods 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.

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.

Charging the transmitter battery

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.

Charge current

To avoid damage to the transmitter the maximum charge current should not exceed 500mA (0.5 A) with the charge circuit fuse out of circuit (not fitted); with the charge circuit fuse in place: max. 1.5 A.

Notes on recharging transmitter batteries using an automatic charger

• Observe the recommendations provided by the charger manufacturer and the battery manufacturer 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 particular if you are using an automatic charger designed 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.

Transmitter description

Transmitter callouts

Control stick length adjustment

To adjust the stick lenght, use the 2mm Allen wrench (supplied with your mx-12 transmitter) to unlock the set screw. Turn the wrench counterclockwise to loosen the screw. Then turn the stick clockwise to shorten or counterclockwise to lengthen. After the control stick lenght has been adjusted to suit your flying style, tighten the 2mm set screw. If you desire longer sticks, GRAUPNER offers a stick that is approximately one inch longer than standard. This stick, crafted from bar stock aluminum, is available at your local GRAUPNER dealer.

Neck strap attachment

An eyelet is provided on the face of the mx-12 transmitter that allows you to connect a Neck Strap. This hook has been positioned so that your transmitter has the best possible balance when you use the neck strap.

Control Stick tension adjustment

Control Stick tension adjustment

Remove the battery and six transmitter back screws as shown on the previous page. Remove the transmitter back, being careful not to cause damage to any components. Adjust each screw for desired tension (counterclockwise to loosen stick feel; clockwise to tighten stick feel.) When adjusting the throttle ratched tension, make sure that the adjusting screw does not touch the PC board after adjustment is complete.

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).

Direct servo control (DSC)

1. 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.
2. The mechanical conversion is now completed; check the stick actions are as required and reassemble the transmitter by reversing the above process, not forgetting 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 tame 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 causing interference.

For proper DSC hook-up and operation:

1. Leave the transmitter power switch in the OFF position. The transmitter will not transmit any radio frequency (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 adjustments 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.

Connections and installations

For Airplane

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 grommets and brass eyelets to isolate them from vibration. 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 provides the proper security as well as the proper vibration 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.

Dual Rates and Exponential; Servo Reversing

Dual Rates and Exponential

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.

Accessing the Dual-Rate and Exponential Function

1. Place the transmitter power switch in the ON position.
2. Access the Function mode by pressing the Down and Select keys simultaneously.
3. Press either the Up or Down key until D/R EXP appears in the upper left corner of the LCD.
4. Press the (+) ir (-) key until the desired channel (aileron, elevator or rudder) appears.
5. Select the switch position for which you want to adjust the rate. The number to the upper right of the current rate value on the display indicates the current position of the Dual-Rate switch for the channel that you have selected. Either a 0 or a 1 will be shown, corresponding to the position of the switch. To select the opposite switch positio, move the appropriate Dual Rate switch to the opposite position. The number that appears above the current rate value reflects the change.

6. Adjust the rate for the channel and the switch position just selected. To decrease the throw rate, move the cursor to the D/R position using the Select key, then press the (-) key. To increase the throw rate, press the (+) key. As stated previously, the adjustable rate is from 0-125% for each switch position and channel.

7. Press the Up arrow key to access the REVERSING SW menu.

8. Press the Down arrow key to access the SERVO TRAVEL SCREEN.

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 affects 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 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 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.

Ch3 3 Servo CCPM
(Graupner style, most popular)

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 Elevator 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.

2. To exit the THROTTLE HOLD function, press the Down and Select keys simultaneously.

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.

Hovering Throttle Lever Settings

The Hovering Throttle lever increases or decreases the engine output power for the middle three points set for the middle three points set for the throttle curve. As shown in the figure below, use of the hovering throttle lever shifts the curve upward or downward parallel with the original curve. Therefore, operation of the hovering throttle knob does not cause any change to the original settings of the throttle curve.

The throttle trim range will affect the throttle curve as shown.

The adjustable range of output using the hovering throttle lever is approximately + / - 9%

Note: The Hovering Throttle has no effect on flight mode switch position 1.

Pitch Curves

Adjustment of the pitch curve is very similar to the throttle curve adjustment described in the preceding section. A thorough understanding of the Throttle Curve Section will make pitch curve adjustment easier to understand. There are three independent types of pitch curves available: Normal, Stunt, and Hold. Each pitch curve contains five adjustable points: LOW 1, MID 3, and HIGH.

Note: The pitch curve for the Throttle Hold function can only be set if this system is activated.

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 acceleration and deceleration swings should be ignored. The Accerlation Mixing function is provided to compensate for the main rotor acceleration (and deceleration) 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 affects 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.

Trainer Function

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 when 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.

There are three different wing types to choose from; select the one that will best suit your RC aircraft. Flaperon, Elevon and V-Tail are available selections for Wing Type and will be covered in the following pages.

Wing Type V-Tail indicator

Definition of Wing Types

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 unavailable.

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.

Accessing and Utilizing the Flaperon Wing Type Selection

1. While the Down and Select buttons are pressed, move the power switch to the ON position to access the System mode.
2. Press either the Up or Down keys until WING TYPE appears in the upper area of the LCD.
3. Press either the (+) or (-) key to turnon the Flaperon (FLPR) Wing Type Selection.

Note: For Flaperon, one servo must be used for each aileron control surface.

1. Plug the left wing aileron servo into the Auxiliary 1 (AUX1) port of your JR receiver. Connect the right aileron servo into the aileron port (AILE) of your receiver.
2. Check to make sure that the wing servos move in the proper direction. For a right turn, the right aileron should raise while the left aileron lowers simultaneously. For a left turn, the opposite is true; the left aileron should rise while the right aileron drops. If your servos are not moving in the direction just described, use the Servo Reversing function to reverse the travel direction of the servo(s) that are moving improperly. Refer to the Servo Reversing section for information on how to reverse the travel

System Mode

direction.

Note: Each servo's travel direction is adjusted individually through the Servo Reversing function.

Once the servos achieve their proper travel direction, adjust their travel amount, dual rates, sub-trim and aileron differential.

Note: The applicable channel's left or right travel adjustment may be made individually by accessing the Travel Adjust function. Refer to the Travel Adjust section of this manual for more information. The fine adjustments of your aileron controls should be made in the Dual-Rate function. Refer to the Dual-Rate section for information on how to do so. You can also adjust the neutral point of your aileron servos individually through the use of the Sub-Trim function. Refer to the Sub-Trim section of this manual for more information.

1. The flap lever located on the left face of the transmitter controls the aileron movements as flaps. To turn off flaps go to the Flap System function on page 39 and reduce the flap value to 0% .

Note: Differential is offered for the Flaperon function of your mx-12. For more information, please refer to the Differential section of this manual.

1. Press the Down key to access the SWITCH SEL function.
2. Press the Up key to access the MODEL SEL function.
3. Exit the WING TYPE function by pressing the Down and Select keys simultaneously.

Elevon Type Selection

Elevon Wing Mixing is available as an option with your mx-12. This style of aircraft also employs two wing

servos. However, there is not an elevator present. Instead, an elevator stick input causes the two wing servos to function in conjunction with one another to change the pitch movement of the aircraft. Also, when an aileron control is given the two wing servos move in opposition to one another to function as ailerons.

Connect left servo to the aileron port of the receiver
Connect right servo to the elevator port of the receiver

Accessing and Utilizing the Elevon Type Selection

1. While the Down and Select keys are pressed, move the power switch to the ON position to access the System mode.
2. Press either the Up or Down key until WING TYPE appears on the LCD.
3. Press the Select key to select the Elevon functions.
4. Press either the (+) or (-) key to turn on the Elevon Wing Type function.

Note: The Elevon function requires one servo for each elevator, i.e. a separate servo for each wing half.

1. Plug the left elevon servo to the aileron (AILE) of your GRAUPNER receiver. Connect the right elevon servo into the elevator (ELEV) port of your receiver.
2. Check to make sure the servos move in the proper direction. When an input is given from the elevator stick, they should move in unison to achieve the proper up/down elevator command. If your servos do not move as described above, use the Servo Rever-

sing function to reverse the travel direction.

Note: Each servo's direction is adjusted individually through the Servo Reversing function. For more information, refer to the Servo Reversing section in this manual.
7. Once the servos direction has been set, adjust their travel direction, travel volume, dual-rates, sub-trim and aileron differential.
Note: The applicable channel's left or right, up or down travel adjustments can be made individually. Refer to the Travel Adjust section in this manual for more information.
8. Relative to the note above, each servo's travel volume is automatically reduced to 75% of the operating range. This is to ensure that the servo does not operate beyond its capabilities. Failure to observe extreme caution when adjusting the value for the elevon servos may result in damage to the servos by over traveling.
Note: Fine adjustments of the elevons should be made in the Dual-Rate function. For more information, refer to the Dual-Rate section in this manual. You can also adjust the neutral point of your levon servos individually using the Sub-Trim function as described in the Sub-Trim section of this manual. Differential is offered for the levon function of your mx-12. For more information, refer to the Differential Aileron Mixing section of this manual.
