David,

Since flying a model outdoors is so much fun, what I have done is to record a flight with a video recorder on board, and then play in my PC, ............and even post it on YouTube:

Control a RC model from a computer is illegal, at least in USA.
For FPV (First Person View) flights, AMA regulates the following:

"An FPV-equipped model must be flown by two AMA members utilizing a buddy-box system. The pilot in command must be on the primary transmitter, maintain visual contact, and be prepared to assume control in the event of a problem."

You can read the full regulation here:
