Fossoman.... I dont know if the reciever could cause your prob or not???? But my Eflite Rx crapped out on me in much the same way. It wasnt so Isolated though. It would just run for a while and then quit sending to the motor out of nowhere, reguardless of gyro or flight mode. Anyways that incident was what finnaly pushed me into the Dx7 purchase.

Feelin' for ya, Noah
