Compass calibration
The compass is easily interfered by other electronic devices, resulting in abnormal flight data to
cause the normal flight , and even flight accidents, we need often calibrate the compass to keep the
compass in optimal working condition (recommended to calibrate the compass before the first
flight)
Compass calibration steps
1: Turn on the remote control and turn on the power of the flight control system.
2: Switch the switch of control flight mode back and forth between any two flight modes more
than 6 times quickly until the LED indicator blue light is on and enters into the calibration
mode.
3: (Picture 1) Aircraft rotate (about 360°) through the direction of level and gravity as axis
until the green light is on;
4: (Picture 2) The aircraft is erected with the nose facing down, and the direction of gravity is
the axis rotation (about 360°) until the green light is on, so the calibration is completed;
5: After the calibration is successful. After the white LED flashes 4 seconds. The calibration
mode automatically exits. If the calibration fails, the red light flashes 4 seconds. Please
re-calibrate the compass from step 2. (The calibration steps are as shown below)
during transportation should be carried out to avoid rain, exposure and mixed transportation
with corrosive materials.
