4.4 Attentions about compass calibration
4.4.1 Keep the drone away from any metal or radio device during the calibration, even metal in cloth, such as a watch, or mobile phone.
4.4.2 Please check the offset after calibration, the value of X, Y, and Z should be less than 300. Otherwise, re-calibrate the compass.
4.4.3 Put the drone on the group and double-check the actual orientation of the head (for example, use the compass on your phone). The value should be within + - 10 degrees compared to the HUD's. Reverse the VTOL, the value should change accordingly and quickly. Otherwise, re-calibrate the compass.
4.4.4 When the Home position is more than 200km from the last calibration position, re-calibrate the compass.
