Change rotate direction of motor
How to check motor / ESC numberUse Betaflight Configurator to see which ESC controls which motor. To check, the motor will rotate, so remove propellers for safety.
Connect battery to drone and turn on slider to the left of "I understand the risks, the propellers are removed..." that appears at the bottom right of the screen. Then move one of the motor slider on the screen up a little and corresponding motor will rotate. The motor number at this time corresponds to the ESC (Electric Speed Controller) number.
You can move the slider in small increments by clicking on it and pressing the up and down arrow keys on PC keyboard.
