I have received my I1 back from repair at DJI Europe BV where the Flight Controller (baro unit) was replaced. I am now seeing an anomaly when I yaw the aircraft. Instead of rotating about the vertical axis it appears to be turning about one of the landing legs (see video). It is happening both when hovering at ground level and in the air. I have completed 2 full IMU calibrations and calibrated the compass (see screen grab). Has anyone seen this behaviour or suggest a fix? Having been deprived for 2 weeks I don't particularly wish to return it to DJI.
