I've got 250 flights totalling 7hr 20mins on my i1 now. I had non of the reported issues since day one and only had good performance and very stable flights. That was until Firmware v22.214.171.124. Does not matter if I do IMU cal before every flight, multiple compass cal's or restarting the i1 and controller, I keep getting very erratic movements as well as a lot of toilet bowling during my first 10minutes of hover. I say hover because that is exactly what I do until I am VERY sure that things seems more stable. Flights after that seems fine, but I have no confidence while flying them. It makes flying the machine a headache instead of a pleasure. Using one battery just to get the thing airborne seems to be such a waste. I don't even feel like playing in ATTI anymore either. What worries me is that it seems that most owners feel that .17 actually fixed problems for them. Thus DJI think that they are making progress. And me? I'm moving backwards.
