RE: Serious Question
I think 1/10 and 1/8 far out number the large scale stuff in use.
When the local scene around a track (or the area someone is will to drive to it) has enough large scale to warrant it adding a track, only then will they change.
Don't kid yourself, cost is a HUGE factor, with 1/10 cars starting at $100 and 1/5th at $1000 (new Losi is $1600)! Then the track also needs to be larger, and that means more property is required as well (for an outdoor track).
Indoor tracks, thats another whole ball game!
