strange behavior when take off in postion hold mode

Postby luckpl » Fri Mar 18, 2016 5:10 am

Hi, everyone
when i switch to PH, then arm and take off, my drone become nearly uncontrollable:it starts to move in circle (radius 1~2m),and after about 10 seconds, it becomes normal.
this phenomenon just appeared sometimes, not everytime.
other guys have this problem?

Check the primary flight display in QGC before take off.
Does the heading /yaw of the display match with the orientation of the craft?
I guess not. Aa mag calibration might solve the issue.

Cheers
