4. The Aircraft Status Indicator shows the current flight mode when calibration is complete. If

the Aircraft Status Indicator becomes blinking red, repeat the steps above to recalibrate the

compass.

When to Recalibrate

1. The compass data is abnormal, and the Aircraft Status Indicator is blinking red and yellow

alternatively.

2. Flying in a new location, or a location that is different from your last ight.

3. The mechanical structure of the MG-1 is changed.

4. Severe drifting occurs in ight, i.e. the MG-1 has difculty ying in a straight line.

Calibrating the Compass

The compass is built in the landing gear. Be sure to calibrate the compass before your rst ight,

or else the aircraft cannot work properly. The compass is a very sensitive instrument that requires

regular calibration to ensure optimal flight performance. Abnormal compass data due to a lack

of calibration can lead to poor ight performance or even failure. Regular calibration enables the

compass to keep optimal performance.

DO NOT calibrate your compass where there is a chance of strong magnetic interference,

such as magnetite quarries, parking structures, and underground steel reinforcements.

DO NOT carry ferromagnetic objects such as cellular phones with you during calibration.

DO NOT calibrate besides massive metal objects.

DO NOT calibrate in an indoor space.

Calibration Procedures

Choose an open space to carry out the following procedures. It is recommended to calibrate the

compass with an empty tank.

1. Flip the Flight Mode Switch back-and-forth at least 6 times, until the Aircraft Status Indicator

becomes solid blue.

2. Hold the aircraft upright and rotate it 360 degrees along the central axis, until the Aircraft Status

Indicator changes from solid blue to solid green.

3. Hold the aircraft with its nose facing up and rotate 360 degrees along the central axis.
