Whenever I fly my drone I get a message about the IMU needing to be calibrated. When doing this calibration I'm supposed to "place the aircraft on flat and dry surface as indicated", which it is per the attached image.
Despite the drone being in the position and facing the direction indicated the IMU Calibration hangs 95% of the way through step 2. It's been on that status for like 10m and nothing. I'm doing the calibration in the middle of an empty parking lot, which means that there's an abundance of space.

Any ideas?

Hi there, please refer to this tutorial to calibrate the IMU. See if this sorts out your issue.
