I have a FT A1000 with a Canon M6 attached. When balanced it sits reasonably eft on the plate, so that when the main arm rotates, it hits the base mount. I figure if it were attached more to the right, the new centre of mass would mean when balanced, the arm would be free to turn 360° I have a video which describes this better - here Any suggestions for fixing this? I thought an offset plate, but I can't find anything that moves it the amount I need it to
