I guess I just see things differently than you guys...
Most look at rc racing as an expensive hobby. I chose to look at it as a cheap way to race.
I think no matter the hobby people will spend there entire "leisure" budget however they see fit. If all of a sudden all rc stuff was half price I think we would all spend the same money, but end up with more stuff.
If I fished I'd be complaining that my boat only has the 200hp outboard and not the 250 because I can't afford it...
