How about providing tlogs and/or data flash logs to help troubleshoot your issue.

This is usually a sign that the motors/props are not lined straight up and slightly tilted. Use a bubble level to check each motor hub and adjust. We’ve had this happened awhile ago and took 2 days to figure it out.

The logs would show the CCW motors working harder than the CW ones. A clear giveaway.

Ill take alook but you can hear the rpm diffrence between the 2 motors for left ya and the diffrence for the right yaw when applyied
