yaw stability on v quad.

hi everyone!I come in search of some help on a quadcopter that I recently built. I am flying an auav-x2 pixhawk clone on a asymmetrical quadcopter configured as a v frame within parameters. I am flying 3.3 rc 3 and have tried auto tune several times and it now flies fairly well with a few issues. When I yaw, this thing likes to jump all over the place. It is predictable and hasn't caused anything to lose control, but it is far from stable and causes some fairly dramatic altitude movement. I have included two links that show this behavior. The movement in the videos was induced from yaw inputs only. The right stick was not touched during these clips.https://youtu.be/05wAF_2nIGYhttps://youtu.be/apW5ngiuQ1oCan anyone offer any insight on tuning/settings that could be tweaked to help this behavior?

  • I wish. I see the same behavior on an APM, no matter if set to X or V frame.

    What helped was reducing ACRO_YAW_P, but that also means that you will turn slower, of course.

    I think the motors may not be able to keep up with the slowing down and speeding up as quickly as the copter expects them to, so it adjusts for roll and pitch, but the copter doesn't turn at the rate it expected, and wobbles.
