Guys,
The Northern California Scale Racing Association (NCSRA) has a great website with interesting content which includes their racing rules and classes. I'm sure you'll find them of interest so click the links to check them out:

There's lots of other stuff worth reading on the site, so click around,

NCSRA rules and classes
Re: NCSRA rules and classes
Very interesting (both conduct and rules). Many of their classes seem to be motor-restricted but allow significant modifications otherwise. The class that seems closest to ours in terms of specs. is the Modern F1.
