like to give you some information on how to deal with possible problems.
Problem

throttle/brake lever is released
The vehicle does not drive in a

opposite to movement of
steering wheel and throttle on the
transmitter
The vehicle becomes slower or the
steering servo only shows weak
responses.

Remedy
• Check the battery pack in the vehicle.
• Check the batteries in the transmitter.
• Check the connection of the battery pack.
• Check the on/off switch of the vehicle and the transmitter.
• Check the description on the crystals (same frequency?
transmitter and receiver crystals inserted in the correct devices?).
• Change the crystals to a different channel.
• Adjust neutral position for the drive function using the trim on the
transmitter.
• Adjust the steering function using the trim on the transmitter.
• Check the steering linkage.
• Check the play in the steering/wheel suspension and, if necessary,
replace worn parts.
• Check the servo reverse function on the transmitter and, if
necessary, switch it.
• Check the battery pack of the vehicle (allow the motor/speed
controller to cool down before inserting a new battery pack and
continuing to operate the vehicle!)
• Completely pull out the telescopic aerial of the transmitter.
• Unroll the aerial of the receiver and install it properly (in the
vertically mounted aerial tube).
• Check the batteries in the transmitter.
• Check the battery pack in the vehicle.
• Check the description on the crystals (same frequency?
