3.Before Operating

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

•Always use fresh batteries for your transmitter and receiver before running the car. If the radio does

not have full control of the car with steering, throttle and brake. Do not run it until corrected. Failure

to correct this will result in possible injury and damage to the car or property.

We strongly recommend using a failsafe. But remember failsafe does not protect all power is lost

•Please confirm the steering and throttle is at neutral position.

4.Check Your Vehicle After Runing

•After running radio controlled car, it is necessary to perform routine maintenance.
