3.Before Operating

•Make sure that all screws and nuts are properly tightened.

•Radio-Check battery life before running the car. If the radio does not have full control of the car with
steering and/or throttle/brake, do not run until corrected. Failure to correct this will result in possible
injury and damage to the car or property.
