I was wondering what "things" can cause the P3S to throw a compass error, exit GPS while up 400' in the air?  There's no metal up there.  I have received these and wondering what it could be?  I calibrated at the field I was flying in.  

All I can say is that 'it happens'; even with the new craft with dual compasses. So far, I've just proceeded to fly with caution and nothing untoward has happened.

Well, that's good to know, that it's happening to others and on "newer" aircraft.
