2. Accel Calibration

Click SETUP/Mandatory Hardware/Accel Calibration to enter the Accel Calibration.
Accel Calibration needs to be done in two situations:
  1. 1.
    You just receive the drone and test it for the 1st time.
  2. 2.
    Test it after leaving the drone in the workshop for over ten days.

3. Level Calibration

3.1 Put the VTOL on the horizon and click Calibrate Level to complete the level calibration.
3.2 Put the VTOL on the ground and keep it level under QHOVER mode, The 2 aileron servos and 2 tail servos should keep in the original position after calibrated or with tiny movement. Calibrate Level should be re-do when the movement is noticeable.

4. Compass calibration (compass calibration-free drone can skip this step)

4.1 Click SETUP/Mandatory Hardware/Compass to enter the Accel calibration.
4.2 Click Start to start the compass calibration.
4.3 The bar will move forward when rotating the drone in different sides. After the bar is 100%, Click OK and restart the power to complete the calibration.
4.4 Attentions about compass calibration
4.4.1 Keep the drone away from any metal or radio device during the calibration, even metal in cloth, such as a watch, or mobile phone.
4.4.2 Please check the offset after calibration, the value of X, Y, and Z should be less than 300. Otherwise, re-calibrate the compass.
4.4.3 Put the drone on the group and double-check the actual orientation of the head (for example, use the compass on your phone). The value should be within + - 10 degrees compared to the HUD's. Reverse the VTOL, the value should change accordingly and quickly. Otherwise, re-calibrate the compass.
4.4.4 When the Home position is more than 200km from the last calibration position, re-calibrate the compass.

5. Airspeed calibration

6. RC controller mode checks

6.1 SC knob of RC controller is down: VTOL hovering under quadcopter mode (QHOVER).
6.2 SC knob of RC controller is middle: VTOL circling under fixed-wing mode (Loiter).
6.3 SC knob of RC controller is up: VTOL return to launch (RTL).
