This is only the 2nd onboard video I have taken from my new brushless gimbal.
For the first video, I was using 16 silicone O-rings to isolate the gimbal from the aircraft chassis, and unfortunately they proved too soft, as swaying / wobbling was noticeable in the video.
For this video, I have exchanged the O-rings for wire-rope isolators, and it seems significantly better. Unfortunately there are still occasional high-frequency vibrations present, in particular at: 1:15 (vertical climb section), 1:50 (the hard banking section where the gimbal slips in the roll axis by 20-30° or so!) and around 2:00 (returning back towards the people – very harsh vibration).
I'm not sure if the vibration is caused by the gimbal not being quick enough to compensate for vibrations in the airframe, or if the gimbal is oscillating in directions which cannot be compensated by the gimbal ... I'm fairly sure the sudden roll movement around 1:53 can be solved by increasing the motor power on the roll axis, but I don't know what to do about the occasional high-frequency vibration. It was pretty gusty, so not ideal conditions, but at least it's highlighted a potential weakness in the gimbal / airframe ...
Any thoughts as to where I can concentrate my efforts would be most appreciated!
