A person would have to treat it like a vacation. Pay for tuition, motel, food, and travel. If that's what they want to do with their vacation buying dollar, great. But I for one have a family who would frown on me taking a vacation to learn to fly r/c. Obviously there is a small demand for it but after you add up all the cost, I'd rather buy a big gas plane and spend a month learning for free.

Just my opinion. I'm not saying it is good or bad, it just wouldn't have worked for me.
