Need help tuning out oscillations (video).

[epyonxero]

Ive been flying my Y6 with AQ 6.6 R19 for a couple weeks now and I cant seem to get rid of a wobbling oscillation. Heres a video of what my Y6 is doing while in ALT/POS hold, it looks the same in manual, everything is as balanced as i can get it. This it TILT_ANG P at 20 and other PIDs at defaults. Ive tried raising P and the oscillation remains but just sharper, less sloppy. Raising either D term seems to make the oscillations shorter and quicker. Any ideas?

It would be useful if you could take a video and record a log of a short demo flight like this and post them both. The problem might not be entirely PID tuning.

Here is the full log file.

Hi epy,
seems to be similar to the problem that I had. If you have oscillations you need to lower pid values, not raise. In my case, see my topic in pid tuning, it was tilt rate d. I also had high amplitudes in the motor curves.

I get errors trying to access your log file, but based on what I see above, you are clipping. There is way too much controller output. Like Shogun said, reduce PID values, significantly. Start by cutting them in half and then go from there.
