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.
A coiled telescopic aerial, disturbances on the radio channel used (e.g. other models, radio transmissions
from other devices) or adverse transmission/reception conditions could also be a cause for unusual re-
sponses 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 of 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 a new, fully
charged driving battery.
Before the next drive, wait for at least 5 – 10 minutes until motor and speed controller have cooled down
sufficiently.
i) 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.
• When the vehicle has stopped, switch off the speed controller.
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 the driving battery from the speed controller. Disconnect the plug-in connection completely.
• Now you may turn off the transmitter.
Attention!
The motor, the speed controller and the driving battery become hot during operation! Do not touch these
parts immediately after operation. Danger of burns!
