Scale model B-52
How cool is this?
That’s what I’d consider an appropriate application of boyish entheusiasm and technology.
It weighs 300 lbs uses 8 of these at around $ 3,000 each fully configured!
My brother, who is currently into RC planes, showed me the videos of this thing in flight. I agree, it’s pretty amazing.
He was recently at a RC get-together. Someone there had a model B-12 (I think-- I may have the number wrong) that was pretty impressive too. But it wasn’t as big as the B-52 in the link.
That is indeed awesome.
Let me see if I can get you pics and movies of the 1:18 757 and L-1011s we use as test vehicles in aerodynamic research. Almost as cool as the B-52, and similarly powered. They’re available on the NASA Intranet, but I need to ask about releasing them to members of the public.
Damn I’m really becoming evil. My first thought as soon as I saw that was it would be really fun to build a scale model Mig-23 or so and shoot it down. 
I never got around to asking about release of our pictures, but here’s a link to an article about the project. Link
When you get to the mention of computer systems and software to fly the beasties, that’s me. 
There is combat RC where they tie a cloth to planes and try and chew the other guy’s off with the prop. You’re talking about another solenoid for a .22, though, aren’t you? 
That would be Joe Nall that you’re speaking of. My Fiance went and took the video camera so that I could see what I was missing. That plane looked enormous! Next year I’m definitely going!
Just out of curiosity, how much payload can a model airplane carry? Like this 1:12 scale C-130, for instance.
And a completely unrelated question, 
how much do paintball guns weigh?
I posted too soon. I found a kit of a 1:10 scale C130. And the site says it can carry 10 lbs of payload!
Holy cow! It costs $2245, engines not included.
