Does someone has a quick idea what may cause the discrepancy. I noticed while flying forward a little faster, that the copter performs a roll combined with a more severe yaw rotation. It was not really possible to counter the yaw rotation while flying fast To do so I have to slow down and turn. The frane is balanced and the ESCs are calibrated. Unfortunately, the compass was not logged, but it is mounted 20 cm over away and loiter works well. In the logs I observed spikes or gaps (don’t know how to call it). I am not sure whether this is associated with my observation.
