Ensure the compass is calibrated before every flight. Failure to calibrate may lead to poor flight performance or a crash.
Do not attempt to calibrate your compass where there is a chance of strong magnetic interference. This includes areas where there are massive metal objects, parking structures, steel reinforcements underground, or under bridges.
The compass should always be calibrated when moving from indoor spaces to outdoor spaces.
If the rear LEDs show a fast blinking red light, compass calibration has failed. Please recalibrate.
After successful calibration, the compass may become abnormal when you place the aircraft on the ground. This may be because of underground magnetic interference. Move the aircraft to another location and try again.
When to recalibrate:
When compass data is abnormal, and the Aircraft Status Indicator is blinking red and yellow.
When flying in a new location, or a location that is different from your last flight.
When severe drifting occurs in flight, that is the aircraft does not fly in straight lines.
