From my observation of the local RC scene, the one area that seems to have a LOT of kids playing along side their parents is the crawler scene which to me is about as exciting as a glass of water and plain toast but.....it seems the only place I see kids excited with a controller in their hands.

The other day a kid and his parent came in while I was running laps on the indoor carpet with the TT-02 and they walked out with a Mini Z......again not my thing but at least the kid has a controller in his hand.

Racing venues are just competing for the same people and as Billy mentioned, often overlap and conflict as there are only so many decent days of the week to get people together.
