Compass problem

Putting together the new quad using an APM 2.5 and mostly it seems to be working, but the compass consistently reads about 60 degrees off in the Mission Planner display. If I alignit to the north, the readout MP shows Northwest. I have the dec set correctly, and I don't have the same issue with my other quads using the APM 2. Any ideas? I have recalibrated several times, and still no dice.I have tried shifting things around and running the motors up and down and don't see a change so I doubt it is interference.I am baffled.

  • Well, I have no idea what the problem was, but I erased the EEPROM and re-installed 2.8.1 and now it is all working properly.
