RE: Handwriting on the wall?
This hobby is so great that it will survive. I like glow the best, and have taken on mixing my own glow fuel to make sure I will always be able to fly them. I have over 200 engines. so I don't have to worry about availability. I also have an expanding number of gas and electrics that definitely have a place in my hobby. Building / designing my own is every bit as much a part of my hobby as the power plant. I pickup kits / plans to make sure I always will have that as well. I have balsa everywhere to make sure I can build when ever the mood hits me. I think each one of us have the ability to make sure your individual hobby ( whatever that is to you) can continue with just a little fore site.
