Im getting really bad alt hold. The quad wants to clime or fall and will not hold its altitude. This is my first build and cant seem to get it to work.
I think I might have bad vibrations of my barometer might be bad.

I had that problem , it looks a vibration problem. do you have a .log
So yes it was a vibration problem. Work so much better when I put in some dampening. I just find it hard to understand if I have high vibrations.

I just read in other post that 3.3 vers is going to solve this problem with vibs :)
The problem with high Z vibrations is that it can exceed the 8 g range of the accels. Believe it or not it can filter out vibrations from ~ 1 g on the Z accel with a vibration great enough to exceed 8 g. This causes clipping and information is lost, copter thinks its falling so the inav causes a rapid climb. The solution was to set the accels for +/- 16 g range. I think it samples at a higher rate, so don't know if this change could be done to 3.2.1 and work on APM. It might, but I don't think the devs are going to support APM's any more. Just use the last good version. I think this change could be worked back to 3.2.1, maybe.
They are saying v3.3 does not fit on the APM.
