Just got my Movi pro and seeing the same issue. That axis of balance is pretty important in aerial mode, which is what we primarily do. On my m15 with it balanced perfectly I could get pan gain settings of 270. Today on an auto tune at 80% it was at about 140. So it's definitely having an affect. Is it actually the case that as standard it is off balance then on that axis then? If that is the case I'll probably try and counter balance it by putting accesories on the other side of the gimbal until it is properly balanced.
