Hi,
I've had just fine results with the onboard apm 2.5 compass. The various online arguments against using it seem to make sense and I would like the whole setup to be as accurate as possible so I'm giving it another shot. When the compass is plugged in to the i2c port, the direction changes erratically and mostly points south in MP. Compass is on a hacked together delrin/wood/CA glue/3m mount.
I oriented the compass as you can see below, drone silk pointed at the hex's front (receiver is in front) Y backwards.
I followed these instructions. The jumper on APM was never bridged: http://copter.ardupilot.com/wiki/co...ce/#<strong>Instructions-for-APM-2.5<-strong>
Using none for the compass orient, I've tried some others with no change. I do live calibration w/ data radio, away from buildings. Anything I should try?
