I just got myself a gopro gimbal from ebay, and long story short I've accidentally connected the tilt wires (powered) from the gimbal wrongly on to my receiver and I think this may have broken my APM 2.5 board.
I've got the APM 2.6 with an external compass and the offsets are always >400 on all axis (X,Y,Z) no matter where I place it on the frame, away from metals and close to metals. I've done the live calibration at least 20 time
