Troubleshooting

Even though the model and the remote control system were built according to the state of the art, there may still be
malfunctions or errors. For this reason, we would like to give you some information on how to deal with possible
problems.
 The model does not respond
• For 2.4 GHz remote control systems, the receiver must be taught to the transmitter. This process may be referred to
by the terms of „Binding" or „Pairing". The teaching process usually was performed by the manufacturer already;
however, it can, of course, also be done by you. Also observe the separately enclosed operating instructions for the
remote control system.
• Is the throttle/brake lever in its neutral position?
• Programme the full throttle position for forwards/reverse driving and the neutral position; see chapter 10. a).
• Are the vehicle's drive battery, the receiver battery or the batteries/rechargeable batteries in the transmitter discharged?
• Did you switch on the transmitter first and then the receiver power supply and the speed controller last? Always
observe this order!
• Is the drive battery connected to the speed controller correctly?
• Is the receiver battery connected to the corresponding connection plug correctly?
• Is the vehicle too far away? With a fully charged receiver battery and fully charged batteries/rechargeable batteries
in the transmitter, the range should be 100 m and more. The range can be decreased by outside influences, such as
transmitters working on the same or an adjacent frequency, proximity to metal parts, trees, etc.
The position of transmitter and receiver aerial to each other very strongly influences range. It is best when both the
transmitter and receiver aerial are vertical. If you point the transmitter aerial at the vehicle, the range will be very
short!
• Check the correct position of the speed controller and steering servo plugs in the receiver. If the plugs are twisted by
180°, the speed controller and steering servos will not work (if the plugs of speed controller and steering servo are
swapped, the throttle/brake lever will control the steering servos and the wheel will control the driving function).
• Are the servo and speed controller plugs connected in the right orientation?
 The vehicle does not stop when the throttle/brake lever is released
• Set the neutral position on the transmitter correctly by using the trimmer for the driving function.
• If the trimmer's trimming path is not sufficient, put the trimmer into its centre position and then reprogram the speed
controller; see chapter 10. a).
