I grew up with trains... still like them but no interest in starting that up. I've been on and off very tempted to try a stick-and-tissue rubber-powered plane... spent a good bit of time gazing at the Easy-Built Ritz. Concluded that I'm going to have equal difficulties finding an opportunity to fly it, and even worse problems with storage. But all that balsa work really does call out to me.Hmm, you enjoy building but are frustrated at not flying what you've built. This is very dangerous; this is the sort of situation that leads to taking up second hobbies. First it'll be just one innocent airplane, and before you know it you're mainlining trains.
