My hi tech radio just quit working out of the blue yesterday.. I have checked the battery and both receiver and transmitter are charged up. When I turn on the switch the green light goes on (on the receiver) so it must be getting power from the battery to the radio. It almost seems that the receiver is not talking to the servos. Any thoughts would be appreciated. Thanks!

It happens. Just send back to hitec for repairs.

The model of the transmitter and receiver would aid in diagnosing your problem.

It was a connection problem. Got it fixed.
