What to do if steering/throttle operation is intermittent on my Arrma Motorized Toy Car?

If you're experiencing intermittent steering or throttle operation with your Arrma Motorized Toy Car, it could be due to: * The MEGA ESC shutting down because of overheating. Stop driving and allow the MEGA ESC or motor to cool down. * The Tactic transmitter and receiver unit not being properly bound. Check for sources of interference and re-bind the transmitter/receiver.
