I have had this issue from day one. The image on the screen appears to start yawing on it own and sometimes will not stop. If I push the yaw centering button, camera returns to center. Latest firmware installed, Dji has replace my ship and now the gimbal... Tried multiple IMU, COMPASS and Gimbal Calibrations, cold and room temp. Still exhibits this behavior. Any suggestions as to what I am doing wrong? LEaving the country in two weeks for a really important gig.
