Thanks. I used to race MR4TC SD and their fuel cars on-road, so I'm already familiar with the availability of parts and helpful customer service in the US. Great cars, but I did get tired of having to drag $500 parts with me. I think I'll probably keep this one to play around with. Our LHS is in a shopping center with a large asphalt parking lot, and I know it's pretty slick and smooth 'cause I've run other cars on it.
