Simple BGC gimbal sudden movements to stabilize pitch

Hi guys,

Please check out the following video

Camera is properly balance in pitch. With motors off, it stays in whatever pitch angle I decided. However when I turn motors and simulate pitch movements on the dron, as you can seen, the gimbal try to correct the perturbation with sudden movements.

In order to crrect this behaious, I was playing mainly with P, D a motor power for pitch (now set in 4, 2 and 210 respectively). What else would you recommend me to do? Notice that this is not happening in roll.

What other parameter should I change to try to fix this behaviour? That does not sound to me as low or high frequency oscillation. So… what parameter may be affecting this?

Thanks in advance.
