Is this a kit programmed with the governor in it?
More than likely , these esc's come with an arming procedure... If you follow it, it will.. May be... Take away that issue. You have to bind in throttle hold every battery, throttle hold off you'll hear beeps and then on again, and then off and then fly.
Or else if its a mcpx v2.. While binding the board to your Tx, did you hold the rudder stick right to have it bind? If that's not followed, board will act up in giving esc the signals.
Once all that is good, check the gear mesh. My mcpx BL did that. The issue was gear mesh and I had to elongate the motor holes a bit and get the gear mesh right to have to stop doing that. It also frees up a ton of power!
Fly safe!!

have fun!
