RE: CRASHED plane due to servo chatter!! :>(
Doug
The chatter you mentioned did not crash the plane. In fact servo chatter is commonly noticed after a fresh battery charge. If you had walked a few feet away from the plane, the chattter should have stopped. Your transmitter was swampping the receiver causing the chatter. After the crash, you turned on the receiver without turning on the transmitter and the servos again chattered. This too is normal, as there was no controlling RF carrier from the transmitter. The recceiver picked up stray signals causing the servos to go wild. It is always recommended to turn on the transmitter, then the receiver, and vice versa when you turn the units off. (receiver first, then the transmitter).
I agree with Gray Beard about the Y- harness being the culprit. I have never trusted them and have never used them.
