I'm using a Corally CCT at the moment (waiting for parts for my FK05..), and it's a blast!!
I race alongside ordinary touring cars, and it works fine. I broke my first
part at the last meeting.. and that was the first part for a LONG time.. It's super tough!
In GB, they are racing a low-cost class caled Mardave V12. It's a simple 1/12 chassis, with an "ordinary" body on top (Golf/Rabbit, Clios, Mini's and lots of others..). This class looks like great and cheap fun! And they say it's pretty close racing too..

I think this is a great way to get people, at all ages, into the sport of rc-racing! It doesn't cost a lot, it's durable, has few parts and suits all levels of racing - amatures and pros.
