Hello,
I have been flying AC2.9 on my QAV500G for a while. It works great. I now upgraded to AC3.1 and suddenly I get very high frequency oscillations in roll (low amplitude). If I reduce my P-gains drastically the oscillations disappears, but then the QAV gets sloppy.
Is there an explanation on why this could happen when moving from 2.9 to 3.1? I have performed all calibration steps except for the ESCs.
Best regards,
Pål

Vibration at the FC?
Can you post logs?
I have recorded IMU-data in a log today. It was a short flight as the oscillations are severe. Still, as I read the IMU data the vibration levels are within the tolerances given in the Wiki.

Interesting......
I too loaded the latest code into my standard 3DR quad, APM 2.5, no tweaking of code.
It flew fine.
I then did a COMPASSMOT in CLI, and suddenly the quad is all over the place.
Reloaded the code, no COMPASSMOT, and the quad flies just about perfect, again.
Just my 2 million Zim $'s.......
>2 million Zim $
I remember paying 42 trillion for a couple of bananas. I actually still have a 100 Trillion $ note.
