The roll axis is perfect.

Pitch, not so good. I get a bump in the movement when transitioning into forward or backward flight with backward flight being the most noticeable--nose of aircraft pitches up so gimbal wants to rotate down to compensate. When hooked up to the GUI, I can duplicate the bump by precisely stopping the rotation at the exact point of the bump in which case I get a jiggle of about two-three per second. I've spent hours trying to adjust it out and the best I can get is with a PID of P=11 I=.11 D=16 PWR=69.

Any suggestions on adjustments?? TIA.
