...And I've never had any problems in about 30 flights. Pictures are level, drone hovers just fine. Neither the user manual nor the quick start guide say anything at all about doing so, and the app has never prompted me to do it. Any reason why the community is so adamant on doing so every few months, including right when you get the drone? Why wouldn't DJI themselves suggest you do so (or at least provide instructions)? Am I risking serious problems if I'm flying without having done an IMU calibration? First post - though I know IMU calibration is frequently discussed, I'm not sure this particular topic has been brought up.
