Have occurred weird problem with second compass and its calibration.
Here already problem was explained by another forum member. :
I thought, I have same situation, some magnetic field affect on my compass. I just demount pixhawk + gps(with second compass) from plane. Mount it to wood rail, far from any magnetic fields, Do calibration one more time , but still problem exist. Second compass have weird shift during calibration process.
Try with different versions of Adpuplane.
I need advice from more experienced users
Thanks a lot.
