After testing, I know this is the best course of action for what I'm doing and I can see on my bread board that unplugging the ground gives me one function I'm needing and plugging it back in gives me a different function I'm wanting.
The arduino's signals from the servo library methods seem to be powerful enough to drown out all signals coming from the radio control unit. I'd thought that sending the:ailerons.detatch();command (from the servo library) would be enough to give me back control but apparently not.
But, what you want to do is fairly easy. Just use a MOSFET connected something like this:
