Hi all,
I am using A2 controller system and while flying, the platform will sway and rotate occasionally. The led module only blinks red after a crash previously but it should only be  a led problem. I suspect it may be a feedback algorithm or IMU. Can any experienced users point me in the correct direction on what may be the problem? Could it be some gain settings that I have to change? I have a video, notice that everytime it starts to sway it rotates a little prior. See 48second of video. Sometimes it drifts upwards or in different directions. Please help!!

Wow, that was scary to watch! I would contact DJI, it should not be that bad even with incorrect gains.
