anyone can help me with my plane??why roll and pitch not stable
There is no problem with the plane. The scale on the left side is in degrees. This data shows your plane was level with some vibration causing spikes of +/- 0.5 degrees. That is not a problem.
If you have a problem in the future please include the .bin file, not a screen shot. This is usually done dropbox or a similar service and a link.
Good luck with you project.
thanks Greg_Fletcher
but the problem when seen in the mission planner, the plane tilted to the left 5-10 degree
and this .bin and .tlog file.
