The steps for horizontal calibration are as follows:
Step 1. Place the aircraft on a level ground and ensure that the fuselage is level and vibration-free.
Step 2. Perform the outer horoscope locking action on the remote control and hold for more than 10 seconds until the status indicator light starts flashing blue and green alternately.
Step 3. Release the joystick of the remote control and keep the throttle at the lowest level. After about 10 seconds, the status indicator light changes to a single flash of blue indicator light. After about 15 seconds, the status indicator light flashes normally.
Place the aircraft horizontally, perform the outward locking action, and release the lever for more than 10 seconds.
Indicate the current GPS status and wait until the blue and green lights flash alternately after the flight mode 1b5.
Note: If during future flights, the aircraft still tilts severely after taking off in attitude mode, it is recommended to perform horizontal calibration again.
