STEP3: Hold your aircraft vertically and rotate it (its nose is downward) around the vertical axis (about 360 o )
until the LED turns off, meaning the calibration is finished.
STEP4: The LED indicator will show whether the calibration was successful or not.
 If the calibration was successful, calibration mode will exit automatically.
 If the LED keeps flashing quickly Red, the calibration has failed. Switch the control mode switch one
time to cancel the calibration, and then re-start from step 1.
Tips:
If you keep having calibration failure, it might suggest that there is very strong magnetic interference around
the GPS & Compass module, please avoid flying in this area.
