11. 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.
Also observe the operating instructions on the remote control system used by you and the motor and speed controller
installed by you.
The model doesn’t respond or does not respond properly
• 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. Observe the operating instructions for the remote control system
used by you.
• Are the vehicle drive battery or the batteries/rechargeable batteries in the transmitter discharged? Exchange the
drive battery or batteries/rechargeable batteries in the transmitter for new ones.
• Did you switch on the transmitter first and then the speed controller?
• Is the drive battery connected to the speed controller correctly? Check the plug connection for whether it is conta
-
minated or oxidised.
• Is the vehicle too far away or are there interference influences?
The range can be decreased strongly by outside influences, such as interference on the transmitter frequency, or
proximity to other transmitters (not only remote controller transmitters but also WLAN/Bluetooth devices that also
use a transmission frequency of 2.4 GHz), metal parts, buildings, 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 (both aerials are parallel to each other). 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 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).
• If the trimming path is not sufficient, reprogramme the neutral and full throttle positions. For this, observe the opera
-
ting instructions of your speed controller.
