I could sit here for the next hour listing reasons why people don't fly C/L and why trying to get anyone new involved is a losing battle, but it all comes down to a few things. There is no place to get the stuff locally. It's expensive. There's no place to fly. No one new is really interested anyway. And finally the big one, the people involved are generally well meaning, but they often ruin the fun of it. To newcomers, the internet is the most accessible part of what we do. What are those people going to see when they log in? It's not so bad here, but on the other forum the hot topics are all arguments over the most trivial aspects.
I'm 29, I've been flying C/L for close to 20 years now, and there have always been kids too young to drive dragged out to fly. As soon as they're old enough to drive they aren't involved anymore. There are always the old guys, but anytime there is anyone in the middle, 14 to say 40-something, they don't stick around long. Whether it's just the other options they have, or the hurdles involved, or the attitudes, is anyone's guess. But nearly once a week I wonder why I bother. I've been inviting friends to come out and try C/L since 1989 and haven't gotten anywhere with it. I usually get tired of pestering them and give up. When I can't get them to come try it with my hardware, how can I convince them to build their own stuff?
I read an R/C clubs newsletter not that far back, and it was interesting to note they were having the same recruiting problems that C/L has had. Their solution was to target the retreads. When you think about it, how many names can you come up with, of people who you used to fly with that just disappeared? Maybe picking up the phone book is the answer.
