Notes:
1) Always check and change radio batteries when low. Running your car with low batteries
will greatly shorten the radio range. Loss of radio control will damage your car and is not
covered under warranty.
2) Check linkage operation for steering and throttle before starting your car. The directional
servo switches on radio may be in the wrong position and must be checked and set for
proper operation.
3) Battery problems are the biggest cause of car damage, always check radio operation when
running. If you feel the radio is not working correctly, shut down engine immediately and
check it out!
