• When you have finished using the vehicle, switch off the speed controller and fully disconnect the battery
from the speed controller. Then switch off the remote control.
• The range of the remote control decreases when the batteries are nearly empty. Replace the batteries
when necessary.
When the vehicle battery is nearly empty, the vehicle will slow down and may not respond properly to
the remote control.
In addition to powering the motor via the speed controller, the vehicle battery also generates the neces-
sary voltage/current for the receiver and the steering servo.
This voltage is generated via an integrated BEC ("Battery eliminator circuit", an electronic circuit that
supplies a voltage directly to the receiver without an additional receiver battery).
If the battery voltage is too low, the receiver voltage may drop and the vehicle may not respond to remote
control commands.
If this occurs, stop driving the vehicle immediately (switch off the speed controller, disconnect the battery
from the vehicle and switch off the remote control). Replace/recharge the vehicle battery as necessary.
• The engine, drive, speed controller and vehicle battery heat up during use. Pause for at least 5–10
minutes before changing the battery.
• Allow the vehicle battery to cool down completely before charging.
• Do not touch the motor, speed controller or rechargeable battery until they have cooled down. Burn
hazard!
• When the vehicle is powered by a LiPo battery, ensure that undervoltage detection is switched on (we
recommend 3.0 V/cell or higher).
If undervoltage detection is switched off, the LiPo battery may be permanently damaged due to overdis-
charge. This will void the warranty/guarantee!
When the vehicle is powered by a NiMH battery, undervoltage detection should be switched off to ensure
that the vehicle can use the battery's full capacity. Recharge/replace the battery when the vehicle starts
to slow down. Alternatively, configure a lower undervoltage detection setting. See section 10b for details.
