How about 1/8th inferno gt's? They are bigger (more visable to the spectators) so you could get some sponsors logos such as your local club or hobby shop on there to help promote the sport. And you could fit 1/8th offroad tires on them. You could also fit a brushless conversion kit from novak in them if you want to go electric. Man I bet they'd hall a$$ on the ice. The other great thing about the 1/8th rally cars is they have sealed electronics cases to keep the water out of the receiver.
