High frequency VTOL Tuning problem

Hi, Guys

I tuning VTOL Quadplane, flying wing 3m. span. Wingtips were oscillating during PID tuning for multirotor. I’m not sure that induced the whole airplane or the PID gain cause this problem. Which parameter can reduce this oscillation?

This is a part of this tuning. You can see more in the full log.

This is most likely D term, have you tried Qautotune?

I did the Qautotune before manual input PID gain. My plan was finding some reasonable PID gain and Qautotune later. Starting with 1axis Qautune, the battery was not enough to make it complete.
