Your are going to need to be more specific in what you are trying to do. All outputs on the RC are tied back to the +5 volt internally regulated power rail. Although the 5 volts is unused in the speed controllers, it is used in the servos. If you are using the RC for non competition controls there is a variety of things you could do, but... For competition, you may not put any custom circuits between the RC and motors, solenoids, etc. that will affect the devices other than the parts supplied, i.e. speed contollers, spike relays, servos, and team LEDs.
