1: Turn on the transmitter and set the throttle to max.
2: Press down button 1 and 4, keep pressing until last step. Releasing the buttons aborts the calibration.
3: Turn on power to the FC
4: Wait for the ESC to beep its full throttle calibrated signal. When You hear two short beeps put the throttle all the way down. Wait until you hear one short beep then release the buttons.
The ESC’s are now calibrated
