That looks nucking futs!
I saw in one pic you have a square movement limiter, but in the later pics they are round (unless the gimbal does the limiting)
Make sure you have a square limit of movement!
cheers Julian:)
The limiting is done within the gimbal. The CAM plate movement is limited by two screw heads. The round cut out is pure cosmetic, the stick won`t contact with it and will have square boundaries.
