RE: R/C the most expensive hobby ?
Expensive hobbies. Let's see. I've dropped probably about $2,500+ in my R/Cs, about another $800+ on 1/32 scale slot cars, $8,000 in my 1973 Dodge Dart Swinger, about $700 worth of musical instruments that I hardly ever play anymore, about another $2,000 on high end tools(Snap-On, Matco, Mac, Craftsman, etc...), and soon to be about $6,000 in parts/software for a high end computer that I plan to build. That's all I can think of off of the top of my head.
