14. Troubleshooting
Even though the model is a state-of-the-art product, there can still be malfunctions or faults. For this reason, we would
like to give you some information on how to deal with possible problems. Also observe the enclosed operating instructions
for the remote control system.
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?
• 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. 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 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).
• Are the servo and speed controller plugs connected in the right orientation?
The vehicle does not stop when the throttle/brake lever is released
• Correct the driving trimming on the transmitter (setting neutral position).
• 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).
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.
The vehicle doesn't drive in a straight line correctly
• Set straight driving at the transmitter using the respective trimming control for the steering function.
• Check the steering rods or wheel alignment setting.
• Did your car have an accident? If so, check the vehicle for any defective or broken parts and replace them.
