Thats what I mean by the Castle link. You remove esc wire from the rcvr and the wire from the end of the 3 pin pcb connects to the rcvr instead.
i know but i dont have the 3 pin pcb
Go to their website,what i have is the field link
i figured it has the same function anyway and there is already a usb port on the mamba max
