Just to show you how much the industry has changed, how many model airplane books are in your local library? I remember in the 1970's, that even the small public libraries would have at least one or two model airplane magazines on the rack. There would be a section of books in the 629.133 section. Standards were Keith Laumer and Walt Musciano how to design, build and fly books. Bookstores and magazine shops would have model airplane magazines and some books.Recently I went to a small community library, there was nada, zilch.
Typically, feedback I get from those with grandchildren is they'd rather be messing on line with their tablets and smart phones rather than go out and learn to fly.
Regarding "pretty soon", attempting to find a 1.0 cc (0.061 c.i.) or smaller airplane kit is getting tougher. Some are modifying electric kits in order to fly glow.
