Hi I have an unstable flight. The drone makes small deviations along the roll and pitch axis every few seconds, but still can balance itself quite well (drone can stabilise itself within 2 oscillations) even in strong wind.
I have tried advice from these thread and improved my roll angle diagram:
From this:

To this:

But random oscillations still occur.
I was trying to make auto-pid tuning but received “autotune failed” message in QGroundControll each time, without a description in logs or in the app at all.

i am sorry man, but this is funny. Also fyi auto-pid in my experience does absolulety nothing. You have to manually change the P, D and I values and tune yourself.
