I just turned 70. Been building and crashing models of all kinds since 1939. Started R/C in 1958. We had to build our own radios or use a single CB freqency. That was okay though, we only wanted to fly one at a time. If anyone got in a semi controlled flight he was a hero. Everybody watched every attempt and always had plenty of advice, mostly wrong but who knew? It's been a grand adventure and I've enjoyed every bit of it! I'm having to convert to electric power now 'cause I can't get down and up to start engines. I have a friend who is 85 and still flying.
