The same for me.... The solution was to invert both the roll and pitch axes in the GUI. This only affected the follow mode (works nicely now) but nothing else changed. I guess you have to play with the invert settings until you find a combination that works.

I can confirm changing the invert on my pitch axis solved the follow mode problem for me. I was experiencing the same problems originally discussed . Every thing was tuned perfectly but when i entered follow pitch/roll the gimble just went nuts. I'm running 2.4b6. Also I set the pitch angles in RC trim to -90, 90
