Checked crystals, swapped TXers.....no change. But now I'm noticing I have multiple input problems on my "spare" heli.

1. As already mentioned, the uncommanded inputs.

2. Was having an extremely difficult time maintaining a heading with the spare. Had to use cyclic inputs to help compensate rudder movements. Happened to notice there was no twitching on the tail servo like my primary heli had (which indicates gyro input). Compared the two helis side-by-side (with motor disconnected). Sure enough, tail servo moved when turning the heli on the primary, but no movement at all on the spare.

3. A short time later, when to show my wife how the gyro wasn't working on the spare in comparison to my primary. As soon as contact was made between the battery and heli wires, the motor spun up! Douple-checked stick positions and idle switch.....they're good. Tried the other TX....same thing. ***?

I'm getting the feeling the RX on my spare has some major issues. Possible?

Edit: Just to clarify, the light on the gyro indicates it's working. It even centers the servo once initialized. Just doesn't work after that.
