It appears that the constent power on the Servo outputs is ~7.2v. What I would like to do is be able to send either no power, or full 7.2v power based on either a bummper switch or Channel 6 on controller.
I'm fine with the programming side of things, but I can't figure out how to get the full 7.2v based on any programmatic logic.

This is a real issue for many people, remember that the servo does not work on supplied voltage, it requires PWM encoded direction and speed info. The power is supplied so that the the electronics inside the servo and the motor have a working power supply when the controller generates a PWM signal. Changing the voltage to a servo will not get it to start or run at a variable speed and may in fact damage it. If you read further into the servo spec sheet you will see that they will run over a specified voltage range with 7.2 volts as the nominal. This voltage was determined ( a long time ago) by two factors. Six 1.2 volt NiCad batteries add up to 7.2 volts (a six pack of AA Nicad Cells is a nice rectangular package and is easily available) and three terminal voltage regulators (of which one each is inside of every servo) run happy with a 7.2 volt input. Now a close look at the servos supplied in the kit are of the 4.8 volt type ( I think and will check) which run just fine on 5 volts.
