a) General information
• The unauthorised conversion and/or modication of the product is prohibited for safety and approval
reasons.
• This product is not a toy and is not suitable for children under 14 years of age.
• The product must not get damp or wet.
• Operation of a model (such as a car model) may result in property damage and/or personal injury. There-
fore, make sure that you are adequately insured for the operation of the model by liability insurance. If
you already have purchased such a policy, contact your provider to check that the remote controlled
model is covered by the policy.
• Do not connect the drive motor to electric models before the receiver system has been completely
installed. This stops the drive motor from starting before you are ready.
• Check the functional safety of your model and the remote control system before each use. Inspect the
parts for any signs of damage, such as broken connectors or damaged cables. All moving parts on the
model must operate smoothly, but must not have any play in the storage.
• Operation and handling of RC models must be learned! If you have never used such a model, start very
carefully and get used to the model's reactions to the remote control commands rst. Be patient!
• Do not leave packaging material carelessly lying around, because it could become a dangerous toy for
children.
• If you have any questions that are not answered by these operating instructions, contact us (see
chapter 1 for contact information) or an experienced technician.
5
b) Operation
• If you do not have sufcient knowledge of how to operate remote-controlled models, contact an experienced model user or a model club.
• When putting the device into operation always turn on the transmitter rst. Only then turn on the voltage/
power supply for the receiver in the model. Otherwise, the model car can have unpredictable reactions.
• Before using the model, check whether it responds properly to the remote control commands.
• For a car model, a surface should be selected that allows the wheels to rotate freely. Do not hold the car
model by the wheels.
• For a ship model, make sure that the ship’s propeller can rotate freely. Always keep clear of the rotating
area of the ship’s propeller. There is a risk of injury!
• Ensure that people and objects are kept at a safe distance from engines and any other rotating parts.
• Improper use can cause serious injury and damage to property! Always keep the model in your line of
sight and never operate it at night.
• Do not use the model if your responsiveness is impaired. Fatigue, alcohol and certain medications can
affect your responsiveness.
• Never use the model in an area that may endanger other people, animals or objects. Only operate it on
private sites or places which are specically designated for remote-controlled models.
• In the event of a malfunction, discontinue use immediately and establish the cause of the problem before
using the model again.
• Do not use the remote control during thunderstorms, under high-voltage power lines or in the proximity
of radio masts.
• Always leave the remote control (transmitter) turned on when the model is in use. To turn off the model,
always switch off the motor rst, and then switch off the receiver system. Only then can the remote
control transmitter be turned off.
• Protect your model and the remote control system from dampness and dirt.
• Do not expose the remote control to direct sunlight or excessive heat for prolonged periods.
• The weaker the batteries, the lower the range of the remote control. If the receiver batteries or the receiv-
er rechargeable batteries become weak, the model will no longer respond correctly to the remote control.
If this is the case, stop operation immediately. Then replace the batteries with new ones or recharge the
receiver rechargeable battery.
• Do not take any risks when using the product! Always use the model responsibly, otherwise you may
endanger yourself and your surroundings.

7. Battery information
• Keep batteries out of the reach of children.
• Do not leave batteries lying around, as they present a choking hazard for children and pets. Seek im-
mediate medical advice if a battery is swallowed.
• Batteries/rechargeable batteries must never be short-circuited, taken apart or thrown into re. This may
cause an explosion!
• When handling leaking or damaged batteries, always use suitable protective gloves to avoid burning
your skin.
• Do not attempt to recharge disposable, non-rechargeable batteries. This may cause a re or explosion!
Only recharge compatible rechargeable batteries and ensure that you use a suitable battery charger.
• Please observe correct polarity (plus/+ and minus/-) when inserting the batteries/rechargeable batteries.
• If the device is not used for a longer period of time (e.g. storage), remove the batteries/rechargeable
batteries from the remote control and from the model to avoid damage from leaking batteries/rechargeable batteries.
• Rechargeable batteries should be charged at least once every three months to prevent damage due to
deep discharge.
• Always replace the entire set of batteries or rechargeable batteries. Do not mix full batteries with half-full
ones. Always use batteries of the same type and from the same manufacturer.
• Never mix non-rechargeable batteries with rechargeable batteries.
• For reasons of operational safety, only use disposable batteries for the remote control transmitter. Do
not use rechargeable batteries.
8. Receiver power supply
The receiver can either be operated directly via the BEC circuit of the speed controller or via a separate receiver power
supply. The latter can be realised with four AA/Mignon rechargeable batteries or four batteries. Alternatively, a 4- or
5-cell NiMH receiver battery pack can be used.
If you use rechargeable batteries to power the receiver, they will generally be empty upon delivery and will
need to be recharged.

10. Using the transmitter
The numbers used in these instructions refer to the illustration alongside the text or the illustrations within
the respective section. Cross-references to other gures are indicated with the corresponding gure number.
a) Inserting the batteries
To power the transmitter, you need four alkaline batteries, size AA/Mignon.
Proceed as follows to insert the batteries:
The battery compartment lid (1) is located on the bottom of
the transmitter. Press the corrugated surface (2) and slide
the cover off in the direction of the arrow.
Now insert four batteries into the battery compartment.
Ensure the correct polarity of each of the cells. The negative pole (housing) of the battery (3) must be in contact
with the spiral spring (4). A corresponding note (5) can
also be found on the bottom of the battery compartment.
Slide the lid back on and ensure that it clicks into place.
10
Figure 3
b) Switching on the transmitter
When the new batteries have been inserted, switch on
the transmitter for testing purposes using the on/off switch
(see also Figure 2, Pos. 10). To do this, move the control
knob from the left (OFF) to the right (ON).
The red LED for the operation control (see also Figure 2,
Pos. 13) lights up and shows you the switched-on status
of the transmitter.
The green LED for the low voltage indicator (see also
Figure 2, Pos. 8) lights up permanently and signals the
adequate power supply of the transmitter.
If the power supply drops below 4.3 V, the green low volt-
age indicator will start ashing.
In this case, you should stop operating your model as
quickly as possible. To continue operation of the transmitter, new batteries must be inserted.
After checking the correct function of the transmitter, switch it off again.
Figure 4
11
11. Setting up the receiver
a) Connecting the receiver
The receiver allows you to connect three servos (receiver
output CH1, CH2, CH3) and a receiver rechargeable battery (Bind/VCC). The connections are designed for polarity-proof Futaba connectors and can also be used with JR
connectors, if necessary.
When connecting servos and speed controllers, pay close
attention to the correct polarity of the plug connectors.
The plug contact for the impulse line (depending on the
manufacturer either yellow, white or orange) must be connected to the inner (left) pin contact.
The plug contact for the negative line (according to the
manufacturer, black or brown) must be connected to the
outer (right) pin contact.
The servos and the receiver power supply can be connected in different ways depending on the model in which the
remote control system is used.

CH2Throttle/brake servoSpeed controller
CH3Servo for special functions *Servo for special functions *
* The servo for special functions at receiver output 3 is operated with the operating button for channel 3 (see
Figure 2, Pos. 14). A switching module can also be connected instead of a servo.
** For an electronic model with an electronic speed controller, a separate receiver battery at the Bind/VCC connec-
tor is only required if the speed controller used does not have a BEC circuit. For further information, refer to the
technical documents of the controller.
Warning!
If you still use an old mechanical speed controller that has a BEC plug, do not use it to power the receiver.
Turn on the transmitter and then put the receiver into operation. If the transmitter and receiver are correctly connected
(normally set at the factory), the red control LED in the receiver lights up (see Figure 5, Pos. 16). Check the correct
function of the receiver and the connected servos and then switch it off again.
The voltage applied to this connector is too high. Instead, use a separate power supply with four AA/Mignon
rechargeable batteries or a 4- to 5-cell NiMH receiver battery.
b) Installing the receiver
The installation of the receiver depends on the model. For this reason, you should always follow the recommendations
of the model manufacturer regarding receiver installation.
Independent of this, you should always try to mount the receiver so that it is optimally protected from dust, dirt, moisture, heat and vibrations. Two-sided adhesive foam (servo tape) or even rubber rings that hold the foam-wrapped
receiver securely in place are suitable for fastening.
Warning!
The aerial wire (1) has a precisely determined

present a signicant security risk when operating a model.
Figure 7
13
12. Installing the servos
The installation of a servo (1) always depends on the
model used. For specic information, refer to the design
documents of the model.
However, generally you should try to fasten the servos
with screws in such a way that vibrations are minimised.
For this purpose, the servos are usually enclosed in rubber grommets (2) with metal sleeves (3).
Figure 8
In case of stiff linkages, servos cannot run in the required position. They consume excess power and the model control
behaviour will not be correct.
The linkages must work as smoothly as possible without clearance in the bearings or deections.
Before mounting the servo levers, operate the transmitter and then the receiver and check the correct centre of
the trim on the remote control transmitter (see following
chapter).
Always mount the servo levers at a 90° angle to the linkage rods (see Figure 9, Sketch A).
If the servo lever is at an angle to the linkage rods (see
Figure 9, Sketch B), the control paths in both control directions will not be the same size.
A slight mechanical inclination, which is due to the linkage
of the servo lever, can be corrected later with the trim.
Figure 9
14
13. Trimming the controls
The trim serves primarily to correct a slight skew of the servo levers due to the linkage and the associated uneven
control movements. In addition, you still have the opportunity to slightly adjust the model during operation, for example, when the drive is not straight although the steering wheel is in the central position.
The steering arms should be adjusted so that there is a 90° angle between the servo lever and the steering arms. This
will ensure that the model travels in a straight line.
The GT2+1 EVO remote control has a sensitive digital trim, with which the steering (CH1) and the driving functions
(CH2) can be set individually with two buttons, respectively.
a) Trimming the steering wheel
Press and hold the lower of the two trim buttons (-) for the
steering trim (see also Figure 2, Pos. 12). The green LED
display (see also Figure 2, Pos. 8) starts to icker after
some time.
When the receiving system is switched on, the servo lever
of the steering servo will gradually turn from the centre
position to the end of the trim area.
When the green LED stops ickering and stays lit again,
the end of the trim range is reached and the servo lever
stops.
Now press and hold the upper of the two trim buttons (+)
for the steering trim (12). The green LED indicator (8)
starts to icker again after some time and the servo lever
returns to the centre position.
If the green LED ashes twice briey, release the trim button immediately. The centre position has been reached and
the set value is saved automatically. Even after switching off and on, the last set value is retained.
If the centre position of the digital trim for the steering has been set on the transmitter, the position of the servo lever
on the steering servo can be checked and, if necessary, the lever can be mounted in the correct position. Slight inclinations due to the servo lever interlock can then be corrected using the trim.
Practical tips:
The trim for the steering function is exactly in the centre when the lever of the steering servo at the test does
not move by pressing the reverse switch (see Figure 2, Pos. 15). The steering wheel must be in the centre
position.
Figure 10
b) Setting the driving trim
When using a gas-powered model with throttle/brake servo, the trim setting is the same as for the steering servo.
However, to set the trim value, the two trim buttons for the drive trim are used (see Figure 10, Pos. 11).
When using an electric model with the speed controller, the trim must also be set to the average value. If the speed
controller does not have the ability to program the forward, stop and reverse positions, the centre position of the trim
must be set so that the drive motor is off when the drive control lever (see Figure 1. Pos. 3) is not engaged.
15
14. Checking the steering and driving functions
Now connect the servos or speed controllers used in your model and the power supply to the receiver.
For a better understanding, the steering function is demonstrated using the example of a model car. To
prevent the model from unintentionally starting when checking the control and driving functions, place the
model with the chassis on a suitable base (wooden block or similar). The wheels should be able to turn
freely.
a) Checking and setting the steering function
Turn on the transmitter and, if you have not already done so, set the trim in the centre position for the drive and steering functions according to the instructions in Chapter 13.
Then switch on the receiver. If you have connected and mounted everything correctly, the steering of the model should
react to the rotary movements of the steering wheel (see Figure 1, Pos. 2).
When the steering wheel is in the centre position, the wheels should be straight. If the wheels are at an angle even
though the steering wheel is in the centre position, check the correct position of the lever on the steering servo. The
steering linkage rods can be readjusted, if necessary.
If you steer the steering wheel to the left on the transmitter, the wheels on the vehicle should turn to the left (see Figure
11, Sketch A). If you turn to the right, the wheels should turn to the right (see Figure 11, Sketch B).
Figure 11
Warning!
The operation of the steering wheel on the transmitter requires only slight force. Therefore, it is absolutely
sufcient if you operate the steering wheel only with your ngertips. Attempting to turn the steering wheel
with increased force when reaching the end stop can lead to the destruction of the steering mechanism in
the transmitter.
16
If the wheels turn in exactly the opposite direction as
shown in Figure 11, you can use the reverse switch for
the steering function (15) to switch the effective direction
of the steering wheel and thus the direction of rotation of
the steering servo.
It may then be necessary to set the steering
trim again.
Figure 12
Important!
Set the linkage rods on your model so that the full steering deection to the left and right is achieved without
If the steering deection is too large when operating the model, it can be reduced by means of the dual rate
If you press and hold the lower button (-), the green LED will icker and the maximum possible steering deection will
be reduced. If the upper button is pressed and held, the steering deection increases again. If you turn the control
wheel on the transmitter fully to the side during setting, the setting change can be easily observed.
The setting of the maximum steering deection affects both steering directions simultaneously. The set value is stored
automatically and remains even after switching the remote control off and on again.
any mechanical impact or limitation on the steering.
buttons for the steering function (see Figure 12, Pos. 9).
17
b) Checking and setting the driving function
If you pull the operating lever for the driving function (see Figure 1, Pos. 3) as far as it will go in the direction of the
handle, the model should accelerate (see Figure 13, Sketch A). If the lever is pushed forwards, the model should
brake or switch to reverse drive (see Figure 13, Sketch B).
Figure 13
If the drive of your model behaves exactly the opposite to the illustration shown in Figure 13, you can use the reverse
switch for the driving function (see Figure 12, Pos. 7) to switch the operating direction of the operating lever.
Important!
For a model with an internal combustion engine, adjust the carburettor and brake linkage rods so that the
For a model with an electronic speed controller, different positions of the operating lever for the driving function (forward, stop, reverse) may have to be programmed in the speed controller. Further related information can be found in
the documents for the speed controller. If the speed controller is not programmable, set the trim so that the vehicle is
stationary when the operating lever for the driving function is in the middle position.
throttle/brake servo is not mechanically limited. The trim setting for the driving function must be in the middle position.
18
15. Checking the switching function
In addition to driving and steering functions, the GT 2+1 EVO remote control also offers the option of connecting and
controlling a third servo on the receiver.
If the operating button for channel 3 (also see Figure 2,
Pos. 14) is pressed on the remote control, the output lever
of the servo connected to the receiver output 3 runs from
one end position to the other end position (see Figure 14
below).
The function can be used, for example, to control a special
mechanical function in a model.
Important!
Because the two end positions cannot be set
As an alternative to a servo, a switching module can also
be connected to receiver output 3. Thus it is possible, for
example, to turn the light functions on and off on the model
by remote control as well.
After you have checked or set the correct driving, steer-
ing and switching function, rst switch off the receiver and
then the transmitter.
The model is now ready for the rst test drive.
electronically, any linkage rods must be adjusted so that the servo on channel 3 is not
mechanically limited in its rotational movement.
Figure 14
19
16. Fail-safe function
Your remote control receiver gives you the ability to put the throttle servo or electronic speed controller in a specic
position or in the stop function if a correct remote control signal is no longer received in the event of a fault.
If the neutral position (centre position of the driving function control lever) is set to the fail-safe position, the vehicle
will automatically coast if the radio transmission is disturbed or the model moves out of the transmitter range of the
remote control.
But you can also choose any brake position (for example, 50% braking effect in a combustion model vehicle) as a
fail-safe position. In this case, when setting the fail-safe function, you should x the control lever for the driving function
in the desired position with a rubber ring.
To set the fail-safe setting, proceed as follows:
• Move the operating lever to the desired position.
• Turn the transmitter and then the receiver.
• Then press and hold the fail-safe button (17) on the
receiver.
• The LED (16) in the receiver ashes twice and then
lights up again solidly.
• Release the button in the receiver.
• The fail-safe position is now saved.
• The stored fail-safe position remains stored even after
the receiver has been switched off and on again.
Figure 15
Then carry out a function test, proceeding as follows:
When using a throttle servo, you can give a little gas while the engine is stopped and then switch off the transmitter.
The throttle servo must then run into the stored fail safe position after a short time.
For an electric model with an electronic speed controller, the vehicle should be jacked up so that the wheels can rotate
freely for the test. Then start the vehicle as usual. Move the operating lever for the driving function toward the handle
so that the electric motor starts at low speed and the wheels spin.
If you switch off the transmitter now, the electric motor should stop if previously stored as the fail-safe position for the
centre position of the operating lever for the driving function.
20
17. Switching the digital coding
Your remote control transmitter provides the option of controlling receivers with AFHDS and AFHDS2A digital coding.
The transmitter is factory-set to the enclosed AFHDS2A-coded receiver.
If you want to operate a REELY receiver with AFHDS digital coding, the transmitter must rst be changed over and
then the receiver must be connected to the transmitter (see following chapter).
To switch the digital coding on the transmitter, proceed as follows.
• Switch off the transmitter.
• Move the steering wheel for the steering function (see Figure 1, Pos. 2) to one side until it stops and hold it in place.
• Press and hold the pairing button (see Figure 2, Pos. 14).
• With the steering wheel in the steering position and the pairing button pressed, switch on the transmitter with the
on/off switch.
• Release the steering wheel and the pairing button.
• If the green LED for the low voltage indicator is ashing continuously, the transmitter has switched to the AFHDS
digital coding.
If the green LED ashes intermittently, the transmitter has switched to AFHDS2A digital coding.
• Pressing the pairing button again will save the currently set digital coding.
• Turn the transmitter off and then on again to have the remote control transmit in the set digital coding.
Important:
The receiver supplied with the "GT2+1 EVO" remote control system works with AFHDS2A digital coding.
Therefore, always make sure to program the correct coding on the transmitter!
21
18. Pairing function
For the sender and receiver to work together, they must be paired together with the same digital coding. When delivered, the transmitter and receiver are paired and can be used immediately. Renewing the pairing setting is required
primarily after a change of transmitter or receiver or to correct for interference.
Before pairing the receiver with the transmitter, check whether the transmitter works in the correct digital coding (see
the previous chapter).
To perform the pairing function, proceed as follows:
• Transmitter and receiver must be in the immediate vicinity (about 50 cm distance).
• Switch off the transmitter.
• Disconnect any connected servos from the receiver.
• Connect the enclosed programming plug (18) to the
BIND/VCC connector of the receiver.
• The power supply of the receiver (receiver battery or
speed controller with BEC) is connected to output CH3
of the receiver.
• Turn on the receiver. The LED in the receiver (16) starts
ashing quickly.
• Press the pairing button on the transmitter (see Figure
2, Pos. 14) and hold it down.
• Turn on the transmitter while holding the button. The low
voltage indicator on the transmitter ashes.
• When the LED in the receiver (2) ashes slowly after a
few seconds, the pairing process is completed.
• Release the pairing button on the transmitter.
• Turn off the receiver and the transmitter and remove the programming connector.
• Reconnect the servos/controllers to the receiver.
• Check the function of the system. If the system does not work properly, perform the procedure again or check the
digital coding of the transmitter.
If you have switched the transmitter to AFHDS digital coding and pair with an AFHDS receiver, the LED in
the receiver will not ash slowly after pairing, but will light up solidly.
Figure 16
22
19. Simulator function
If required, you can also use the transmitter on the PC for simulation purposes or games. In this case, you will need a
USB interface cable and appropriate software for the computer (e.g., car racing games, etc.).
The USB interface cable is connected to the PC interface socket on the left side of the transmitter (see Figure 1,
Pos. 5). When properly connected, installed and turned on, the transmitter is recognised by the operating system (for
example, at least Windows XP or higher) and can be used as a standard joystick.
For all other information, refer to the user manual of the USB interface cable.
20. Maintenance and cleaning
This product does not require maintenance. Never attempt to disassemble the product (except for inserting or replacing the batteries as described in these instructions).
Clean the exterior of the remote control with a soft, dry cloth or brush. Never use abrasive cleaning agents or chemical
solutions, as these may damage the surface of the case.
