Hi Kjetil: Can you post a short video clip to show this (preferably with audio). Also, were you using the standard red O-rings, and with all of them in the vibration isolators? Thanks Andy.
Yes, too much D term can be problematic. The cold weather probably stiffened up the mounting for the FC and has created a feedback oscillation at the 'summer' PID tuning. Tabb
