Cube Orange with Hobbywing X9 motor combo

We are trying to get a hexa working with Cube Orange and Hobbywinf X9 motors and corresponding FOC ESC’s (X9 combo). Connecting with PWM is not working. We can’t get the motors connected to Arducopter latest stable release. The ESCs are beeping although everything is connected correctly. When using a cube black with latest stable, it works fine. Anyone having the same or similar issue?

Not sure exactly what is not working as your post is vague. Make sure your PWM values are 1050-1950 and not 1100-1940. It won’t calibrate the ESC’s if the PWM is not set correctly.
