11. 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 doesn’t respond
• Is the vehicle drive battery or are the batteries/rechargeable batteries in the transmitter discharged?
• Did you switch on the transmitter and then the speed controller?
• Is the drive battery connected to the speed controller correctly?
• Is the vehicle too far away? With a fully charged drive battery and fully charged batteries/rechargeable batteries in
the transmitter, the range should be 100 m and more. However, this can be decreased by outside influences, such
as interferences on the transmitting frequency.
• Check the correct position of the speed controller and steering servo plugs in the receiver. If the plugs are inserted
rotated by 180°, the speed controller and steering servo will not work.
If, however, the speed controller and steering servo plugs are swapped, the throttle/brake lever controls the steering
servo, and the wheel controls driving.
The vehicle does not stop when the throttle/brake lever is released
• Correct the driving trimming on the transmitter (setting neutral position).
• When the trimming path isn’t sufficient, switch off the speed controller. Put the trimming at the transmitter to the
centre position. Release the throttle/brake lever at the transmitter.
• Programme the neutral position and full throttle positions for forwards and reverse driving in the speed controller (if
possible). For this, observe the operating instructions of your speed controller.
The vehicle slows down or the steering servo shows only slight or no reaction; the range between transmitter
and vehicle is very short
• The drive battery is weak or discharged.
The receiver power supply and thus also the power supply of the steering servo is usually achieved through the
speed controller BEC. Therefore, a weak or discharged drive battery will cause the receiver to no longer work
properly. Replace the drive battery with a new, fully charged one (before inserting a new drive battery, wait at least
5 - 10 minutes until motor and speed controller have cooled down sufficiently).
• Check the batteries/rechargeable batteries in the transmitter.
