On my gimbal, I placed the arm on the other side of the camera so that I had access to a video link. The standard part and configuration does not allow for this. I also cut in an inset to the bottom for the board placement.
I'm having issues, as my gimbal constantly seems to be trying to acquire center balance, but cant, and vibrates a lot. When I was using the stock metal parts, even after I've reversed the sides, I had it working. My assumption is this has something to do with the change in weight of the mount.
I've asked the original creator if he ran into this issue and how to fix. If anyone else out there has any ideas, please comment and let me know. Otherwise, I'll post a fix when I figure it out in case anyone else runs into same issue.
