Never point the transmitter aerial directly onto the vehicle. It will strongly decrease the range. The maximum range will
be achieved when the aerial of the transmitter and vehicle are both vertical and in parallel to each other.
If the vehicle tends to pull towards the left or the right, set the steering trim on the transmitter accordingly.
When switching between forward and reverse gears, the throttle/brake lever must be put in the neutral position briefly
(approx. 1 second) (neutral position = let go of lever, do not move it). If the throttle/brake lever is moved from forward
to reverse directly, the brake function of the drive is activated (vehicle will NOT reverse).
Wait for at least 5 - 10 minutes until motor and speed controller have cooled down sufficiently before the next run. Only
then start a new drive with a full drive battery.
Stop driving immediately if the vehicle shows any unusual responses to the remote commands or if the
vehicle does not respond at all. This behaviour could be caused by low drive batteries, low batteries/re-
chargeable batteries in the remote control or by too great a distance between vehicle and remote control.
A coiled/damaged telescopic aerial, interference on the radio channel used (e.g. radio transmissions from
other devices, Bluetooth, WLAN) or adverse transmission/reception conditions may also cause unusual
responses of the vehicle.
Since the receiver is supplied with power via the speed controller/drive battery, low or empty drive batteries
will cause unintentional movement of the vehicle (e.g. twitching of the steering servo, etc.).
For example, the voltage of the drive battery decreases for a short time under full throttle, so that the re-
ceiver 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 drive battery.
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.
• After the vehicle has stopped, the speed controllers switch off (switch position "OFF", see chapter 9. g).
Never 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!
Attention!
The motor, the speed controller and the drive battery get hot during operation! Do not touch these parts
immediately after operation. Danger of burns!
• Disconnect the drive battery from the speed controller. Disconnect the plug-in connection completely.
• Now you may turn off the transmitter.
