JATO_82 : I think I've traced the electrical problems down to the receiver. When I plug the Heli's battery in and turn the transmitter on, the gyro doesn't initialize, the roll servo tries to go past full right, and the motor sometime starts by itself for not reason. Could this all be caused by a bad receiver?
Have you verified that your TX and RX are on the same frequency? TX and RX on same signal format (PPM or PCM)?
Good Luck,
