You are solely responsible for the safe operation of the model and the remote control!

4. Product description

With the "GT2+1 EVO" 3-channel remote control, you have a wireless remote control system that is ideal for model

vehicles or model ships. The driving and steering functions can be operated remotely independent of each other via

the two proportional control channels 1 and 2. In addition, the remote control has a third control channel that can be

used for switching tasks or additional control functions.

The ergonomically shaped casing ts comfortably in your hand and thus allows convenient operation of the transmitter

and secure control of the model.

For operation, the transmitter requires four AA/Mignon batteries. Unless a speed controller with a BEC circuit is used,

the receiver requires either four AA/Mignon batteries or four AA/Mignon rechargeable batteries with the corresponding

battery holder. Alternatively, a 4- or 5-cell NiMH receiver battery pack can be used.

Dear customer, these safety instructions serve to protect not only the product, but also your own safety and

that of other persons. Read this section very carefully before using the product.

a) General information

• The unauthorised conversion and/or modication 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.

b) Operation

• If you do not have sufcient knowledge of how to operate remote-controlled models, contact an experi-

enced 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 specically 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/recharge-

able 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.

Before the rechargeable battery delivers its maximum power, several complete discharge and charge cy-

cles are necessary.

If you use several rechargeable batteries, purchasing a high-quality charger may be worthwhile. They

normally charge rechargeable batteries quickly.

9. Remote control buttons

The illustrations in this manual show the GT2 EVO remote control, which is identical to the GT2+1 EVO

except for the switching function. This may cause labels or markings on your remote control to be differ-

ent than depicted in this manual. However, the function notes described in the text refer exclusively to the

GT2+1 EVO remote control.

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 num-

ber.

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 nega-

tive 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.

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 transmit-

ter, new batteries must be inserted.

After checking the correct function of the transmitter, switch it off again.

Figure 4

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 bat-

tery (Bind/VCC). The connections are designed for polari-

ty-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 con-

nected 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.

* 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.

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.

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.

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, mois-

ture, 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

length. So do not wind up, wrap or cut the aerial

wire.

This would severely limit the range and thus

present a signicant security risk when operat-

ing a model.

Guide the antenna wire up through an opening in the

model. It is best to use the antenna tubes enclosed with

the remote control.

Figure 7

12. Installing the servos

The installation of a servo (1) always depends on the

model used. For specic 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 rub-

ber grommets (2) with metal sleeves (3).

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 deections.

Before mounting the servo levers, operate the transmit-

ter 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 link-

age 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 direc-

tions 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 8

Figure 9

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 exam-

ple, 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 briey, 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 inclina-

tions 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.

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.

Figure 10

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 steer-

ing 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

sufcient 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.

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.

Important!

Set the linkage rods on your model so that the full steering deection to the left and right is achieved without

any mechanical impact or limitation on the steering.

If the steering deection is too large when operating the model, it can be reduced by means of the dual rate

buttons for the steering function (see Figure 12, Pos. 9).

If you press and hold the lower button (-), the green LED will icker and the maximum possible steering deection will

be reduced. If the upper button is pressed and held, the steering deection 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 deection affects both steering directions simultaneously. The set value is stored

automatically and remains even after switching the remote control off and on again.

Figure 12

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

throttle/brake servo is not mechanically limited. The trim setting for the driving function must be in the mid-

dle position.

For a model with an electronic speed controller, different positions of the operating lever for the driving function (for-

ward, 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.

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

electronically, any linkage rods must be ad-

justed so that the servo on channel 3 is not

mechanically limited in its rotational movement.

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.

Figure 14

16. Fail-safe function

Your remote control receiver gives you the ability to put the throttle servo or electronic speed controller in a specic

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.

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.
