    After receiving the AIO, first connect to computer on Betaflight software to check whether the gyroscope and accelerometer are detected, and whether the gyroscope attitude is normal.
    Increase the throttle in Betaflight software to ensure the normal rotation and correct rotation direction of the 4 motors, and then install the propellers for a test flight; be sure to remove the propellers when pulling the throttle in Betaflight software to avoid accidents.
    After confirming the above precautions without any problems, you can install the propellers and start flying!
