Hi,

That is good to hear that FMA is standing behind their product. The Co-Pilot is just another piece of electronics and can go bad just like any of the other component in our aircrafts. I think statistically, the odds are in your favor and you shouldn't get two bad ones. Did you have the newer or older version of the Co-Pilot? The new version requires a joystick action to complete the calibration. The older version completed the calibration without any stick movement from the transmitter.
