Hi, I built a two axis stabilizer for my video camera and the issue is that when I tilt the frame right or left 90 degrees and the pitch axis becomes pan axis, the axis is not stable and starts to drift. What can I do to correct this?

This is a link to the stabilizer in action. Thanks to the forum for providing all the info necessary to build a dual motor pitch axis stabilizer with encoders on all axis, very useful info here.
