Aircraft compass calibration
1. Compass calibration should be performed after successful aircraft initialization detection.
2. Aircraft compass calibration should be done for every flight. That is to say, if changing new battery or
the battery is reinstalled, compass calibration should be done again.
Two steps of compass calibration:
Step 1: Horizontal calibration
After successful aircraft initialization detection, the aircraft front and rear lights flash yellow
alternatively. Hold the aircraft horizontally and rotate it 360 degrees along the central axis for
about 3 circles. The aircraft front and rear light will change from flashing yellow alternatively
to flashing green alternatively when horizontal calibration is completed.
Step 2: Vertical calibration
Hold the aircraft with camera facing up, and rotate it 360 degrees along the central axis for
about 3 circles until the front and rear lights of the aircraft change from flashing to solid on,
the compass calibration is successful.
Attention: To fly at GPS mode, please choose an open and wide space for the flight, and
!
● Please do not calibrate the compass in strong magnetic area, such as magnetic field,
!
parking place or construction areas with underground reinforcement.
● Please do not carry magnetic materials with you (such as keys, cell phones, etc) when
calibrating compass.
● Please keep away from big metal when calibrating compass.
make sure that the satellite amount is over 7.
