I've been using the M10 and MR with Blackmagic Cinema Camera + Zeiss CP2 in handheld and airborne mode respectively. I'm finding Pan motor behaves a lot differently in the two modes: In handheld, the Pan gains are set between 50-60 (Roll and Tilt similar). If I put a bit of force on the pan (lightly push with my hand) I can feel it is nice and firm, but not oscillating - perfect behaviour IMO. However in Airborne mode, gains have to be set right up near 200 to get even close to feeling firm, despite roll and tilt still being in 50-60 range. There appears to be a fair bit of 'slop' or 'slack' in the pan motor when I lightly push against it (significantly more slack than in handheld mode, despite nearly triple the gains) More gain does make it firmer, however these numbers are huge, so something must be odd. In reviewing the aerial shots from airborne mode (slung under a Cinestar 8 with MR conversion kit), it appears there is unwanted movement in the pan axis, whilst tilt and roll are perfect. I also notice a humming noise coming from the Pan motor in airborne mode, but not when in handheld mode Thanks for reading my long explanation, I look forward to hearing your thoughts..
