There, the ESCs are calibrated. Or you can check the video one ore two pages back and do it that way (by removing the wire from M1, connect battery, press and hold buttons 1 and 4 and after that connect back the wire from Motor1, the rest is the same).
Thanks guys for the help, sorry that I'm not aware the ESC Calibration function had been removed from the Menu.
I did follow the method and also watch the video but both beeps from my ESC giving 2 beeps even the confirmation beep.
After Armed the board, the 2nd motor (I'm on Quadcopter X mode) is not turning even when the throttle is at max. The rest of the motors turning fine.
Could it due to improper calibration of ESC?
