If the neutral position is not correct (e.g. trimming control slightly off), you cannot switch between forward
and reverse driving. If you have this problem, correct the trimming for the driving function or perform speed
controller programming (see chapter 10. a).
Stop driving immediately if the vehicle shows unusual responses to the remote commands or if the vehicle
does not respond at all.
This behaviour could be caused by low driving batteries, low batteries/rechargeable batteries in the re-
mote control or by too great a distance between vehicle and remote control.
An aerial which is not fully extended, disturbances on the radio channel used (e.g. other models, radio
transmissions through other devices) or adverse transmission/reception conditions could also be a cause
for unusual responses of the vehicle.
Since the receiver is supplied with power through the speed controller BEC and thus through the driving
battery, low or empty driving batteries will cause unintentional movement of the vehicle (e.g. twitching of
the steering servo, etc.). For example, the voltage at the driving battery decreases for a short time under
full throttle, so that the receiver will no longer receive the required operating voltage. The vehicle will speed
up, but the steering servo does not react properly. Stop operating the vehicle at once and use new, fully
charged driving batteries.
Before inserting new, fully charged driving batteries into the vehicle, wait at least 5 – 10 minutes until motor
and speed controller have cooled down sufficiently.
k) Stopping the Vehicle
To stop driving, proceed as follows:
• Let go of the throttle/brake lever on the transmitter so that it goes into neutral position, and let the vehicle run out.
• Once the vehicle is stationary, remove the car body and switch off the speed controller (switch position see chapter
8. g).
Make sure not to touch the wheels or the drive mechanism, and make sure you do not move the throttle/
brake lever at the transmitter! Do not hold the vehicle at its wheels!
• Disconnect both driving batteries from the speed controller. Disconnect the connections completely.
• It is only now that the transmitter may be turned off.
Attention!
The motor, the speed controller and the driving batteries grow hot during operation! Do not touch these
parts immediately after operation. Danger of burns!
