After updating to .7 firmware the video started to shake as shown below. This could have been influenced by the Polar filters - possibly - but after calibrating the IMU and the gimbal twice (both times with filter on) it went away, for the moment. And just to answer your standard questions: yes I've checked the gimbal holders (all good) and did the recalibration as mentioned. Finally it seems ok but haven't had a chance to do a longer test. Let's see later on. Anyhow - I do believe it is interesting to watch - so enjoy ;-)
