No problems in flight to mention but got a strange problem on the gimbal (nothing to do with the Pixhawk).
whilst looking at the logs I noticed more vibration than normal (at least from what I can remember) The soundtrack on the camera also makes me think one of the motors may be noisey or have a bad bearing.
Video from the camera is here - you can see vibrations wandering down into the gimbal - even through 2 sets of vibration dampening. Some odd reaction around the 1:45 time. It as a little breezy but certain not windy
Any thoughts and comments would be greatly appreciated.
