I have some past experience with the Mavic, but not in the past year. I just borrowed a Phantom 3 Pro. When I got it going, it wanted the compass calibrated. Didn't work out (may have been my fault) but GPS was OK so I launched it. It immediately wandered off on it's own, disregarding RTH. Luckily, I found it a mile away with only some broken props.

All fixed up with new blades. Tried to load controller screenshots here, but they're too big.

Aircraft Status > Flight Error Records > Compass Error (with details to fix)

The other day, before the mishap, it said rotate AC 360*.

Today, when I press Calibrate button, it says "Calibrate Compass?" I press OK, but don't get the "rotate AC 360*.  I rotate anyway, but no acknowledement. I wind up with two flashing green and two steady red AC status lights. I'm totally confused. Thanks.
