Hi All,

I've been slowly putting together an APM 2.5 system with my Bixler, I've flown it in stabilize mode which was very cool... but have yet to fly it autonomously.  

Connecting up via USB everything seemed to look OK in Mission Planner.

I don't have the power module, but was powering it from the 4.6V source (from a Quanum Telemetery transmitter) on the input pins.  When I got outside I found the GPS wouldn't lock anymore.  I finally worked out that was from low power.

I soldered the JP1, and now power it from the motor ESC on the output side.  The GPS now gets a good 3D lock.

But now the compass appears wacky.  In Mission Planner with MAVLINK it's not pointing the right direction.  Its out completely, like pointing 180 degrees or more out.

Have I fried the internal compass some how?  Can I get it back?

Thanks for any help
