In the first part of the video the gimbal twitches time and time again. A lot of vibration can be noticed. Then I changed the white dampening balls to the softer black ones (a40), after that most of the vibrations went away and twitching also solved.
Please notice that it was a windy day and sometimes I've reached 22 m/s speed, so some vibrations are there.
T- motors a t-motor carbon props are completely balanced, I don't know wherefrom the rest vibrations come.
