Troubleshooting
Even though the model and the remote control system were built with the latest available technology, there can 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 doesn't respond
• Are the vehicle driving battery or the batteries/rechargeable batteries in the transmitter discharged?
• Did you switch on the transmitter and then the speed controller?
• Is the driving battery connected to the speed controller correctly?
• Do all crystals and receivers use the same frequency?
• Is the transmitter crystal (labelled T or TX) in the transmitter and the receiver crystal (labelled R or RX) in the
receiver? If the crystals are swapped, transmitter and receiver will not work or not work correctly.
• Is the vehicle too far away? With a fully charged driving 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. Try using a different frequency for the two vehicle and
transmitter crystals; see chapter 12.
• 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 servo will not work (if the plugs of speed controller and steering servo are
swapped, the throttle/brake lever will control the steering servo and the wheel will control the driving function).
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 arm.
• If the trimmer's trimming path is not sufficient, put the trimmer into its centre position and then reprogramme the
speed controller; see chapter 10. a).
The vehicle slows down or the steering servo shows only slight or no reaction; the range between transmitter
and vehicle is very short
• The driving battery is weak or discharged.
The receiver power supply and thus also the power supply of the steering servo is achieved through the speed
controller BEC. Therefore, a weak or discharged driving battery will cause the receiver to no longer work properly.
Replace the driving battery with a new, fully charged one (before inserting a new driving battery, wait at least 5 – 10
minutes until motor and speed controller have cooled down sufficiently.
• Check the batteries/rechargeable batteries in the transmitter.
