RE: why
I am not sure if it is an age difference, but when I began doing RC in the '80s it was the hot thing to do. People loved it and were interested in the cars and the people. As it has become popular again, I think that some of us old timers in RC are our own worst enemies. To validate my point, I have a great LHS and another OK one. In the OK one there is a gentleman about my age who, no s**t, acts like the guy form the Simpsons - The comic book guy. If I were a kid getting into this sport and he were the first person I met and he was trying to get me into the sport - I would run. This guy has never left RC or the '80s for that matter. I do not think he is the only person like this in RC.
I love RC and am excited to see another generation getting interested in it. Please don't let other people's opions effect your outlook on it. It is the only activty that you control all aspects of racing. Tuning, racing and troubleshooting. It is a great exercise for the brain.
