3.3.3 Compass Calibration

Because the compass is calibrated out of the box, user calibration is typically

unnecessary. If compass error messages appear, or the aircraft’s flight direction

does not match control inputs, or you fly the aircraft at a very long distance from

your calibration position, follow the steps below to calibrate it.

WARNING

The compass is very sensitive to electromagnetic interference causing

compass error and poor flight. If the compass is still not functioning

properly after calibration, move the aircraft to another location and try

again.

When calibrating the compass, remember to:

 Set up in an open outdoor area.

 Stay clear of all sources of magnetic interference, such as magnetite or

steel reinforcements in concrete. Proximity to large structures may also

affect calibration results.

 Stay well clear of underground and overhead power lines.

 Remove all ferromagnetic materials (such as keys or magnetic jewelry).

 Stay away from electronic devices that might interfere with the calibration

(such as mobile devices).

 Calibration Procedure

1. Start the calibration process by pressing the Take-off/Landing Button ( )

and Go Home Button ( ) on the remote control simultaneously for 3

seconds. The Rear LED Indicators on the aircraft will flash yellow when the

calibration process initiates.

2. Hold the aircraft horizontally and rotate it until the Rear LED Indicators on

the aircraft turn solid green.
