I mean if this 13 year old wants to be cheap and money saving he could just through on board an FMA Direct Co-pilot and one of those new Range Video On-Screen Displays and be the heck done with it. Of course I would probably use a more high tech autopilot if I had the money but frankly I don't. That just leaves you with direct control if you want and, THIS IS A BIGGY, your power plant! What I would use is a fueless permanent magnet engine. It sounds goofy and all but for what the lil' man wants to do it would be the way. What would really be revolutionary is if we could all get together and try to accomplish this marvelous idea together...
