What sumquak said but another thing to remember some receivers won't take over 6 volts so if that's the case wire the red and black wire from the external bec straight to the servo and only connect the signal wire (white or yellow) to the receiver. Don't pull the red wire on your esc so your receiver could be powered by esc bec (internal bec)... hope this all makes sence....
I just tried this set up on my scaler seems to be working pretty good
