General information

The unauthorised conversion and/or modification 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 (for example, a car model) may result in damage to property and/or personal injury. Ensure that you are sufficiently insured, e.g. by taking out private 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 before each use. Inspect the parts for any visible signs of damage, such as broken connectors or damaged cables. All moving parts should move freely, but there should not be any slackness in the bearing.
You must first learn how to operate and handle remote-controlled models before actually using them! If you have never used such a model, start very carefully and get used to the model’s reactions to the remote control commands first. Be patient!
Do not leave packaging material lying around carelessly, as it could become a dangerous plaything for children.
If you have any questions that are not answered by these operating instructions, contact us (see section 1 for contact information) or an experienced technician.

Operation

If you do not have sufficient knowledge of how to operate remote-controlled models, contact an experienced model user or a model club.
Before connecting a rechargeable battery to a model, place the model on a suitable surface. Do not touch rotating parts of the model while connecting the rechargeable battery. There is a risk of injury! 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.
When putting the device into operation, always switch on the transmitter first. Only then turn on the power supply for the receiver in the model. Otherwise, the model may show unpredictable reactions.
Before using the model, check whether it responds properly to the remote control commands.
When operating a model, always make sure that body parts or objects are kept clear of the danger area of motors or other rotating driving 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 specifically 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 turned on when the model is in use. When turning off the model, always turn off the motor first and then switch off the receiver system. Only then may the transmitter be turned off.
Protect the remote control from moisture and heavy soiling.
Do not expose the remote control to direct sunlight or excessive heat for prolonged periods.
The transmitter range decreases as the batteries get weaker. As the receiver batteries (the receiver rechargeable battery or the drive battery that supplies the receiver of the speed controller with BEC) become weak, the model fails to respond correctly to the remote control commands.
If this is the case, discontinue using the model immediately. Then replace the batteries with new ones or recharge the receiver/drive battery.
Do not take any risks when using the product! Always use the model responsibly; otherwise, you may endanger yourself and your surroundings.

Battery information

Warning: Although batteries and rechargeable batteries are very useful in our everyday life, nevertheless they present numerous safety hazards. Always observe the following safety information when handling batteries and rechargeable batteries.

Keep batteries/rechargeable batteries out of reach of children. (Rechargeable) batteries must be kept out of reach of children.
Do not leave batteries/rechargeable batteries lying around, as they present a choking hazard for children and pets. Seek immediate medical advice if a battery is swallowed!
Batteries/rechargeable batteries must never be short-circuited, disassembled or thrown into the fire. This may cause an explosion!
Never damage the outer casing of batteries or rechargeable batteries.
When handling leaking or damaged batteries/rechargeable batteries, always use suitable protective gloves to avoid burning your skin.
Liquids leaking from batteries/rechargeable batteries are highly aggressive chemicals. Objects or surfaces coming into contact with these liquids may be severely damaged. Therefore, keep batteries/rechargeable batteries in a suitable location.
Do not attempt to recharge disposable, non-rechargeable batteries. There is a risk of fire and explosion! Non-rechargeable batteries are only designed to be used once and must be disposed of properly when they are empty.
Always use a compatible charger to charge rechargeable batteries (LiPo, NiMH, etc.) and ensure that the charging specifications are correct. Please always refer to the operating instructions for the charger you are using.
Never charge rechargeable batteries unsupervised!
If you do not plan to use the model for an extended period (e.g. during storage), remove the batteries/rechargeable batteries from the transmitter to prevent them from leaking and causing damage.
Store batteries/rechargeable batteries in a dry, clean, cool place out of the reach of children.
Rechargeable batteries should be charged at least once every 3 months to prevent damage due to deep discharge, which will render them useless.
Never charge damaged, leaking or deformed rechargeable batteries. This may cause a fire or explosion! Discontinue use immediately and dispose of such unusable rechargeable batteries in an environmentally friendly manner.
Observe the correct polarity (plus/+ and minus/-) when inserting batteries/rechargeable batteries into the transmitter or connecting the receiver to the voltage/power supply.
Always replace the whole set of batteries/rechargeable batteries in the transmitter. Do not mix full batteries/ rechargeable batteries with half-full ones. Always use batteries/rechargeable batteries of the same type and from the same manufacturer. Never mix batteries with rechargeable batteries!
Since round cell rechargeable batteries have a lower output voltage (1.2 V) than disposable batteries (1.5 V), we recommend that you use only 4 AA/Mignon batteries (not rechargeable batteries) in the remote control transmitter for operational safety reasons. Otherwise, the transmitter’s voltage will become too low in a relatively short amount of time.

Operating the transmitter

Inserting batteries/rechargeable batteries into the transmitter

Slide the battery compartment cover on the underside of the transmitter backwards in the direction of the arrow to open it.
Insert the four AA/Mignon batteries (or four rechargeable batteries) using the inscriptions inside the battery compartment, paying attention to the correct polarity (plus/+ and minus/-).
Close the battery compartment again.
- Given that rechargeable batteries have a lower output voltage, we recommend using the transmitter with non-rechargeable batteries only for reasons of service life and operational safety. Using rechargeable batteries would cause the transmitter to show an insufficient operating voltage after a relatively short time.

Switching on the transmitter

Release the transmitter controls, do not move them.
Push the on/off switch (see fig. 1, no. 12) upwards.
The LEDs (fig. 1, no. 13) indicate the battery status; the fewer of them are lit, the lower the battery status:
- Empty: The LEDs flashing and a running light serve as a warning signal
Now turn on the receiver or the model vehicle.

Caution: Always switch on the transmitter before turning on the receiver and connecting it to the voltage/power supply or turning on the model vehicle. Otherwise, the response of the model vehicle may be unpredictable. Discontinue using the vehicle when the battery level is too low. Stop operating the vehicle by switching off the speed controller. Then turn off the transmitter and replace the used/empty batteries/rechargeable batteries with new/fully charged ones. You can now turn the transmitter on again and operate the vehicle.

Switching off the transmitter

First, disconnect the receiver from the voltage/power supply and switch off the model vehicle.
Only now switch off the transmitter.

Caution

Always disconnect the receiver from the voltage/power supply (or switch off the model vehicle) before switching off the transmitter. Otherwise, the response of the model vehicle may be unpredictable.
Remove the batteries/rechargeable batteries from the transmitter if you are not going to use it for a long time (e.g. during winter storage). Leaking empty batteries/rechargeable batteries can cause damage to the metal contacts in the battery compartment, thus rendering the warranty/guarantee null and void!

Charging rechargeable batteries in the remote control

On the side of the transmitter, you will find a charging socket (fig. 1, no. 16) that can be used to charge the rechargeable batteries (for dimensions/polarity/charging current, see section “Technical data”). Switch off the transmitter.
Check whether the batteries fitted in the battery compartment are indeed rechargeable.

Caution

Conventional batteries are intended for single use only. Charging non-rechargeable batteries may cause a fire or explosion! Only recharge batteries that are marked as rechargeable.
Only use a charger that is suitable for the respective number of cells in the transmitter and the corresponding rechargeable battery type (e.g. NiMH).
Because of the integrated protective diode in the transmitter, some chargers may cause problems.

Use a suitable charging cable to connect the charger to the charging socket.
After charging, disconnect the charger from the charging socket.
Switch on the transmitter and check the LED display, as described in section 10.2.
- We recommend that you do not charge accumulators directly in the transmitter but instead with a highquality charger for individual cells. In this case, you can charge the batteries faster thanks to higher charging currents depending on the rechargeable battery type and the charger.

Steering wheel for steering

The steering wheel (fig. 1, no. 1) controls the steering servo connected to receiver channel 1. Turning the steering wheel to the left (counter-clockwise) causes the vehicle to move to the left depending on the rotation angle; turning it to the right (clockwise) causes it to move to the right. The following transmitter controls affect the steering function and are detailed in the following sections:

“ST-TRIM” knob (fig. 1, no. 9): set the steering servo to the middle/neutral position (or straight-ahead vehicle travel), as described in section 10.7
“GYRO LV / ST-D/R” knob (fig. 1, no. 11): only when the receiver gyro is switched off: steering servo maximum deflection limitation, see section 10.8
“ST” reverse switch (fig. 1, no. 14): steering function reversal, see section 10.9

Throttle lever for the drive function

The throttle lever (fig. 1, no. 4) controls the speed controller (or a throttle servo of a combustion engine vehicle) connected to receiver channel 2. Pulling the throttle lever toward the handle causes the vehicle to drive forwards (speed depends on the lever position). Pushing the throttle lever away from the handle causes the vehicle to drive backwards or brake (depending on the vehicle). The following transmitter controls affect the drive function and are detailed in the following sections:

“TH-TRIM” knob (fig. 1, no. 2): set middle/neutral position, see section 10.10
“TH-D/R” knob (fig. 1, no. 10): dual-rate setting, see section 10.11
“TH” reverse switch (fig. 1, no. 15): direction reversal, see section 10.12

Trim for the steering function, “ST-TRIM” knob

If the vehicle tends to pull to the left or right while driving, even though the steering wheel is in the middle position, set the steering trim accordingly with the “ST-TRIM” knob on the transmitter (see fig. 1, no. 9). During the adjustment, one of the LEDs (fig. 1, no. 13) indicates the trim position, and the LED display changes back to the battery status if the knob is not moved for approx. 5 seconds.

If the trim path is not sufficient, check whether the servo lever on the steering servo or the steering linkage in the vehicle is correctly positioned. When adjusting, ensure that the neutral position of the steering roughly corresponds to the middle position of the knob.

Gyro sensitivity or dual rate for steering function, “GYRO LV / ST-D/R” knob

The “GYRO LV / ST-D/R” knob (fig. 1, no. 11) has two different functions depending on whether the receiver gyro is enabled or disabled.

Gyro is enabled

The “GYRO LV / ST-D/R” knob (fig. 1, no. 11) allows changing the gyro sensitivity. More details can be found in section 11.

Gyro is disabled

The “GYRO LV / ST-D/R” knob (fig. 1, no. 11) allows limiting the maximum steering angle, thus improving the vehicle steering performance during fast driving, as it responds more sensitively. During the adjustment, one of the LEDs (fig. 1, no. 13) indicates the setting, and the LED display changes back to the battery status if the knob is not moved for approx. 5 seconds.

Caution: If you turn the knob all the way to the left, you will not be able to move the steering servo. Hence, you will not be able to steer the vehicle.

Steering function reversal, “ST” slide switch

Use the “ST” slide switch (fig. 1, no. 14) to reverse the steering servo movement direction (e.g. when holding the transmitter with your right hand and steering with your left hand).

Trim for the drive function, “TH-TRIM” knob

If the vehicle does not remain stationary when you release the throttle lever (middle/neutral position), set the trim for the drive function accordingly using the “TH-TRIM” knob on the transmitter (fig. 1, no. 2). During the adjustment, one of the LEDs (fig. 1, no. 13) indicates the trim position, and the LED display changes back to the battery status if the knob is not moved for 5 seconds.

For a vehicle with an electronic speed controller, reconfigure the neutral and full throttle positions if the trim path is insufficient. For a vehicle with a throttle/brake servo, make sure to readjust the idle position via the corresponding control linkage. When adjusting, ensure the neutral position of the drive roughly corresponds to the middle position of the knob.

Dual rate for the drive function, “TH-D/R” knob

You can use this knob to set the control path for channel 2 (speed controller or throttle/brake servo). You can also use this function to limit the maximum speed of a vehicle for a beginner. If an electronic speed controller is connected to receiver channel 2, speed limitation means that only 50% of the motor power is available despite full deflection on the throttle/brake lever. During the adjustment, one of the LEDs (fig. 1, no. 13) indicates the setting, and the LED display changes back to the battery status if the knob is not moved for approx. 5 seconds.

Please note: If you turn the knob all the way to the left (counter- clockwise), you may not be able to move the drive.

Drive function reversal, “TH” slide switch

Normally, pulling the throttle lever towards the handle on the transmitter causes the vehicle to move forward. Otherwise, use the “TH” slide switch (fig. 1, no. 15) to reverse the movement direction of the drive.

Please note: If the vehicle moves in the wrong direction after unplugging the electric motor from the speed controller (e.g. for vehicle repair), reconnect the motor cables correctly instead of operating the slide switch (for brushless motors, swap two of the three cables to reverse the direction of travel).

EPA setting

The abbreviation “EPA” stands for “End Point Adjustment”, which means the adjustment of the end position.

EPA setting for the steering function: This setting enables you to set the maximum permissible deflection for the steering servo to the left and right to prevent it from blocking mechanically (and thus preventing it from damaging the gearbox). A separate adjustment of the steering servo in both directions of rotation is possible.

EPA setting for the drive function: In the case of an electronic speed controller, changing the EPA setting for the drive function limits the maximum forward and reverse speed. A separate adjustment for the forward and reverse travel is possible. For a combustion engine vehicle with a throttle servo, you can determine precisely the maximum permissible deflection in each direction to avoid mechanical blocking (and thus prevent damage to the gearbox). You can adjust the directions of rotation of the throttle servo separately, which allows the full-throttle position to be set correctly. In addition, you can adjust the maximum braking force where the brake is operated via the throttle servo.

For example, you can use the EPA setting to limit the forward speed but leave the reverse speed unchanged (unlike the dual-rate setting, which changes both speeds at the same time). When changing the EPA setting, it may be necessary to readjust the drive function trim (see section 10.10). In the case of an electronic speed controller, it may also be necessary to reconfigure the neutral and full throttle positions on the speed controller.

To change the settings, follow the steps below

First, disconnect the receiver from the voltage/power supply and switch off the model vehicle.
Switch off the transmitter.
Place the vehicle on a stable surface so that the wheels can turn freely.

Caution: During the EPA setting, both the drive (wheels, axles, etc.) and steering are active and move at full speed. Therefore, ensure the vehicle is securely fixed. Do not reach into the drive or moving parts. Do not hold the vehicle by the wheels!

Push the throttle lever away from the handle as far as it will go (maximum reverse speed), hold down the “AUX1” button (see section 10, no. 6) and turn on the transmitter.
The middle of the 5 LEDs flashes, and the EPA setting mode is active.
Now release the throttle lever and the “AUX1” button; the middle LED should continue to flash.
Now turn on the receiver or the model vehicle by switching on the speed controller or the receiver power supply.
The vehicle should now be ready for operation and respond to the transmitter control commands (left, right, forward, reverse, neutral).
Moving the throttle lever to the “full throttle forward” position (pulling the throttle lever all the way to the handle) causes the drive to run forward at full speed.
Use the “TH-TRIM” knob to change the EPA setting for “full throttle forward”. The LEDs indicate the current setting. The motor speed should change a little as you adjust the knob.
Releasing the throttle lever takes it to the neutral position.
For some electronic speed controllers, you should now briefly move the throttle lever to the “full throttle reverse” position and then release it (neutral position). This is necessary for the speed controller to enable reverse travel.
Moving the throttle lever to the “full throttle reverse” position (pushing the throttle lever all the way away from the handle) causes the drive to run in reverse at full speed (for combustion engine vehicles, the brake will be activated instead of the reverse travel).
Use the “TH-TRIM” knob to change the EPA setting for “full throttle reverse” (or the brake setting for combustion engine vehicles). The LEDs indicate the current setting.
Releasing the throttle lever takes it to the neutral position.
Setting the neutral position with the “TH-TRIM” knob causes the drive to stop.
Move the steering wheel all the way to the left and hold it in this position.
Use the “ST-TRIM” knob to change the EPA setting for the maximum deflection to the left of the steering servo. The LEDs indicate the current setting. The adjustment should enable achieving the maximum steering angle so that the servo is not blocked.
Releasing the steering wheel takes it to the neutral position.
Move the steering wheel all the way to the right and hold it in this position.
Use the “ST-TRIM” knob to change the EPA setting for the maximum deflection to the right of the steering servo. The LEDs indicate the current setting. The adjustment should enable achieving the maximum steering angle so that the steering servo is not blocked.
Releasing the steering wheel takes it to the neutral position.
Use the “ST-TRIM” knob to set the neutral (middle) position of the steering.
Disconnect the receiver from the voltage/power supply and switch off the model vehicle.
Switch off the transmitter. All EPA settings have been made and saved. You can now use the transmitter to operate the vehicle in the usual way.

Button for the “AUX1” control channel

Use the “AUX1” button (fig. 1, no. 6) to control an additional function. Holding down the button activates the corresponding receiver output (see fig. 2, item B).
You may use this button for a separate brake servo of a disc brake in a larger model vehicle. The disc brake is engaged as long as you keep the button pressed.

Slide switch for the control channel “AUX2”

Use the “AUX2” slide switch (fig. 1, no. 5) on the transmitter to activate additional functions; the switch has 3 different positions.
For example, you can use it to control additional lighting or a sound system in the vehicle at the corresponding receiver output (see fig. 2, no. A).

Receiver gyro function

The receiver has an integrated gyro. It acts on the steering servo output so that the vehicle is automatically countersteered if its rear gets out of control. You can select 8 different sensitivity levels for the gyro or switch it off.

Switching the gyro function on/off

_ Please note: _The receiver gyro comes already switched on upon delivery.

Proceed as follows

First, disconnect the receiver from the voltage/power supply and switch off the model vehicle.
Switch off the transmitter.
Place the vehicle on a stable surface so that the wheels can turn freely.

Caution: During switchover, the motor starts up briefly. Do not reach into the drive. Do not hold the wheels.

The flashing receiver LED indicates whether the gyro is activated or not. You can also use a function test described below to determine whether the gyro is enabled or disabled.
Switch on the transmitter and then the vehicle (speed controller or receiver power supply). Wait until the vehicle is ready for operation and responds correctly to the transmitter control signals (steering/drive function; adjust the trim for the drive function if necessary).
Release the throttle lever and the knob for the steering function on the transmitter so that they are in the middle (neutral) position.
Press the “BIND” button on the transmitter three times quickly (see fig. 1, no. 3) to switch the receiver gyro on or off.
The receiver output for the drive function is briefly activated (for electric vehicles, the motor will start briefly; for combustion engine vehicles, the throttle servo will deflect briefly). The flashing receiver LED indicates the current status:
- LED flashes once: Gyro is disabled
- LED flashes three times: Gyro is enabled
Check the gyro function by turning the vehicle chassis to the left or right (20° – 45°) to simulate a swerving vehicle rear. The motor/drive should not necessarily be running while doing this.
With the gyro switched on, the steering servo drives the front wheels in the opposite direction. Use the “GYRO LV / ST-D/R” knob (fig. 1, no. 11) to adjust the gyro sensitivity, as described in section 11.2.
With the gyro switched off, the position of the front wheels remains unchanged. You can now use the “GYRO LV / ST-D/R” knob (fig. 1, no. 11) to set the dual rate for the steering function, as described in section 10.8.
Disconnect the receiver from the voltage/power supply and switch off the model vehicle.
Then switch the transmitter off.
The selected setting takes effect upon restarting the transmitter and receiver/vehicle, and the gyro is switched on or off.

Adjusting the gyro sensitivity

With the gyro switched on, use the “GYRO LV / ST-D/R” knob (fig. 1, no. 11) to choose one of the 8 sensitivity levels. The transmitter LEDs indicate the setting. You can thus enhance or reduce the counter-steering of the steering servo as you wish in case the vehicle rear swerves. You can check the gyro function and the counter-steering of the steering servo by turning the vehicle chassis to the left or right to simulate a swerving vehicle rear. The motor/drive should not necessarily be running while doing this.

With the gyro switched off, you can use the “GYRO LV / ST-D/R” knob (fig. 1, no. 11) to set the dual rate for the steering function, as described in section 11.7.

Checking the steering and drive functions

Place the model vehicle on a suitable surface so that all wheels can turn freely and ensure the model vehicle is stable. Do not touch rotating or moving parts. There is a risk of injury! First switch on the transmitter and, if you have not already done so, set the trimming for the driving and steering functions in the middle position. Then turn on the receiver voltage/power supply (e.g. connect the drive battery to the speed controller and switch on the speed controller).

Steering function

Assuming everything is connected and mounted correctly, the model’s steering should respond to the turning movements of the steering wheel (fig. 1, no. 1). When the steering wheel is in the middle position, the wheels of the vehicle should be aligned straight. If the wheels are at an angle, even though the steering wheel is in the middle position, check that the servo lever is correctly positioned on the steering servo. The linkage rods can be readjusted, if necessary. If you turn the steering wheel on the transmitter to the left, the wheels of the vehicle must turn to the left. If you steer to the right, the wheels must turn to the right.

Caution: Only a little effort is required to operate the steering wheel on the transmitter. Therefore, it is absolutely sufficient if you operate the steering wheel only with your fingertips. Attempting to turn the steering wheel with increased force upon reaching the end stop can permanently damage the steering mechanism in the transmitter. This will void the warranty/guarantee!

If the wheels turn in exactly the opposite direction, you can enable the reverse steering setting. This will reverse the servo direction. Under certain circumstances, a readjustment of the steering trimming may be required. Set the steering linkage on your model so that the full steering deflection to the left and right is achieved without any mechanical impact or limitation on the steering. If the steering deflection proves to be too large when operating the model, it can be reduced with the EPA setting (see section 10.13).

Drive function

Pulling the throttle lever (fig. 1, no. 4) all the way to the handle should cause the model to accelerate. Pushing the throttle lever forward away from the handle should cause the model to brake or switch to reverse (depending on the vehicle or speed controller).

For some electronic speed controllers, reverse travel only applies when pushing the throttle lever away from the handle for the second time (which is meant to prevent rapid switching between forward and reverse travel and hence drive overload). Please refer to the operating instructions for the speed controller you are using. In the case of most vehicles with an internal combustion engine, the carburettor and a disc brake are actuated simultaneously with the throttle servo and a corresponding servo linkage.

If the drive of your model behaves exactly the opposite, then you can enable the reverse setting for the drive function. For a model with a combustion engine, adjust the servo linkage for the carburettor and brake linkage so that the throttle servo is not mechanically limited. The trim setting for the drive function must be in the middle position. You can also limit the servo travel with the EPA setting (see section 10.13). For a model with an electronic speed controller, you may need to set the control lever for the drive function on the speed controller to different positions (forward, stop, reverse). Further related information can be found in the documents for the speed controller. For a non-configurable speed controller, set the trim so that the vehicle is stationary when the throttle lever is in the middle/neutral position.

Auxiliary channels “AUX1” and “AUX2”

Always make sure that the servos do not run against the stop when operating them. This means that the servos do not strike mechanically in the respective end positions. Apart from increased power consumption, this also leads to an overload of the servo gear or the servo electronics.

Keeping the “AUX1” button (fig. 1, no. 6) pressed activates the “AUX1” channel (fig. 2, item B) on the receiver.
The “AUX2” channel (fig. 2, item A) on the receiver has three different positions to be selected with the “AUX2” slide switch.

Pairing function

To ensure that the 2.4 GHz remote control can transmit a signal without interference, the remote control and receiver must have the same digital code. The digital encoding (connection between the remote control and receiver) can be configured using the pairing function (also called “pairing”). The remote control and receiver are usually already paired when they leave the factory and can be used straight away. The devices only need to be paired again if the remote control or receiver has been replaced or to correct a malfunction.

Proceed as follows: Caution, important!

The EPA setting (see section 10.13) for the drive function must be set to maximum for both forward and reverse travel (there must be no speed limit).
Then turn the “TH-D/R” knob (fig. 1, no. 10) and the “GYRO LV / ST-D/R” knob (fig. 1, no. 11) clockwise as far as they will go.
Failure to do so may prevent the pairing process from being completed correctly, as the receiver calibration also takes place during the pairing process (configuration of extreme positions for the throttle lever and steering wheel).

First, disconnect the receiver from the voltage/power supply and switch off the model vehicle.
Switch off the transmitter.
Position the receiver so that it is horizontal. Use a piece of adhesive tape to fix the receiver in place.
Keep the “BIND” button for the pairing function (fig. 1, no. 3) pressed and turn on the transmitter. The LEDs (fig. 1, no. 13) show a running light from left to right. Then release the “BIND” button. The transmitter will now search for the receiver for approx. 10 seconds.
With the running light enabled on the transmitter, reconnect the receiver to the voltage/power supply (e.g. switch on the speed controller).
The receiver LED flashes several times and lights up permanently after a few seconds. The running light stops, and the LEDs light up permanently (and indicate the battery status as usual).
- The receiver is in calibration mode to be set to the extreme throttle positions (full throttle forward/reverse) and the extreme positions for the left/right steering angle.
Pull the throttle lever on the transmitter as far as it will go to the handle (= full throttle forward), then move it back to the middle (neutral) position. The drive does not start while doing so.
Push the throttle lever away from the handle as far as it will go (= full throttle reverse), then move it back to the middle (neutral) position. The drive does not start while doing so.
Turn the steering wheel on the transmitter counter-clockwise all the way to the left, then move it back to the middle (neutral) position. The steering moves as usual.
Turn the steering wheel clockwise all the way to the right, then move it back to the middle (neutral) position. The steering moves as usual.
The transmitter LED will flash three times and then light up permanently.
- If the LED does not flash three times, make sure to check the EPA setting and the position of the two knobs (see instructions for the pairing function) and set them correctly.
Briefly check the vehicle function to see if it responds correctly to the transmitter control signals (steering and motor/drive).
You can now enable or disable the gyro as needed. Please refer to section 11.1.
Disconnect the receiver from the voltage/power supply and switch off the model vehicle.
Then switch off the transmitter.
You can now put the receiver back in place, e.g. in the vehicle’s receiver box. The receiver must be positioned horizontally, with the sockets/plugs facing upwards, and the lateral orientation is irrelevant. Guide the antenna cable out of the receiver box. Stow the remaining cables in the receiver box and close it again, taking care not to pinch any cables when screwing it shut.
- The receiver must be positioned horizontally in the vehicle to ensure the correct operation of the built-in gyro.
Now you can turn on the transmitter again and operate the vehicle.

Disposal

Product

This symbol must appear on any electrical and electronic equipment placed on the EU market. This symbol indicates that this device should not be disposed of as unsorted municipal waste at the end of its service life.

Owners of WEEE (Waste from Electrical and Electronic Equipment) shall dispose of it separately from unsorted municipal waste. Spent batteries and accumulators, which are not enclosed by the WEEE, as well as lamps that can be removed from the WEEE in a non-destructive manner, must be removed by end users from the WEEE in a nondestructive manner before it is handed over to a collection point. Distributors of electrical and electronic equipment are legally obliged to provide free take-back of waste. Conrad provides the following return options free of charge (more details on our website):

in our Conrad offices
at the Conrad collection points
at the collection points of public waste management authorities or the collection points set up by manufacturers or distributors within the meaning of the ElektroG

End users are responsible for deleting personal data from the WEEE to be disposed of. It should be noted that different obligations about the return or recycling of WEEE may apply in countries outside of Germany.

(Rechargeable) batteries

Remove batteries/rechargeable batteries, if any, and dispose of them separately from the product. According to the Battery Directive, end users are legally obliged to return all spent batteries/rechargeable batteries; they must not be disposed of in the normal household waste.

Batteries/rechargeable batteries containing hazardous substances are labelled with this symbol to indicate that disposal in household waste is forbidden. The abbreviations for heavy metals in batteries are: Cd = Cadmium, Hg = Mercury, Pb = Lead (name on (rechargeable) batteries, e.g. below the trash icon on the left).

Used (rechargeable) batteries can be returned to collection points in your municipality, our stores or wherever (rechargeable) batteries are sold. You thus fulfil your statutory obligations and contribute to environmental protection. Batteries/rechargeable batteries that are disposed of should be protected against short circuit and their exposed terminals should be covered completely with insulating tape before disposal. Even empty batteries/rechargeable batteries can contain residual energy that may cause them to swell, burst, catch fire or explode in the event of a short circuit.

Troubleshooting

The transmitter does not respond to commands:

Check the batteries in the transmitter and replace them with new ones, if necessary.
Check that the batteries are inserted correctly.

Servos and/or speed controller do not respond to signals

Check the voltage/power supply of the receiver.
Test the BEC function of the speed controller.
Check the polarity of the servo plugs.
Check the assignment of the transmitter controls to the receiver channels. Check whether the servos or the speed controller are plugged into the correct receiver channel.
Re-pair the receiver with the transmitter (use the binding function).
Check the dual rate setting on the transmitter.
Check the EPA setting of the transmitter.

The servos are shaking

Check the voltage/power supply of the receiver.

A servo is humming

Check the voltage/power supply of the receiver.
Check that the linkage rods run smoothly.
The servo is running against the stop, limit the servo travel using the EPA setting.
For test purposes, operate the servo without the servo lever.

The unit has a low range

Check the voltage/power supply of the receiver.
Check the batteries in the transmitter and replace them with new ones, if necessary.
For test purposes, reorient the receiver antenna. To achieve a high range, the antenna must protrude as vertically as possible from the vehicle.

The transmitter turns off straight away or after a short while

Check the batteries in the transmitter and replace them with new ones, if necessary.

The vehicle does not steer or the steering angle is too low

Check that the steering linkage is running smoothly.
Check the steering servo and steering linkage. It may be blocked by stones/foliage or the like.
Check the connection of the steering servo (channel 1).
Check the dual rate setting of the transmitter (if the dual rate setting is too low, the servos will stop working).
Check the EPA setting of the transmitter.

The vehicle does not move or moves very slowly

Use the “TH-D/R” knob (fig. 1, no. 10) to increase the dual-rate setting for the drive function, as described in section 10.11. Move the knob clockwise to the right.

The model does not respond or responds incorrectly

Release all transmitter controls (especially the throttle lever and steering wheel). Only then switch on the receiver or the vehicle.
Consult the operating instructions for the vehicle/speed controller and reconfigure the neutral and full throttle positions for the forward/reverse travel.
Is the vehicle too far away? The range can also be reduced by outside influences, such as interference in the radio frequency or the proximity of other transmitters (not only remote control transmitters but also Wi-Fi/Bluetooth® devices that also use a transmission frequency of 2.4 GHz), metal parts, buildings, etc.
Guide the receiver antenna cable out of the receiver box and use an upright antenna tube. Do not roll up the antenna cable. Avoid cutting the antenna cable.

The vehicle is not stationary when the throttle/brake lever is released

Correct the trim for the drive function.
Consult the operating instructions for the vehicle/speed controller and reconfigure the neutral and full throttle positions for the forward/reverse travel.

The vehicle moves in the opposite direction to the throttle lever on the transmitter

Enable the reverse setting for the drive function on the transmitter, as described in section 10.12.

The steering wheel moves in the opposite direction to the rotary control on the transmitter

Enable the reverse setting for the steering function on the transmitter, as described in section 10.9.

The steering deflection is too small or the steering does not move

Only when the gyro is disabled: Use the “GYRO LV / ST-D/R” knob (fig. 1, no. 11) to increase the dual-rate steering setting, as described in section 10.8. Move the knob clockwise to the right.
Re-configure the EPA setting on the transmitter, as described in section 10.13.

The steering moves though no manipulation of the steering wheel on the transmitter takes place

The integrated receiver gyro counter-steers if the vehicle rear swerves. The gyro is also operational when the vehicle is stationary, e.g. if you want to turn it or reposition it.
You can disable the gyro if you do not need it (see section 11.1).

The steering deflections via the gyro are too strong/weak

Set a lower or higher sensitivity, as described in section 11.2.
Ensure the receiver is positioned horizontally (the cables/connectors must face upwards). Otherwise, the gyro will be unable to correctly detect the unwanted turning movement of the vehicle and counteract it.

The gyro does not work

Switch on the gyro (see section 11.1).
Ensure the receiver is positioned horizontally (the cables/connectors must face upwards). Otherwise, the gyro will be unable to correctly detect the unwanted turning movement of the vehicle and counteract it.
