As long as the cars are evenly matched, racing is more fun I think. I race R/C sailboats too in the summer with the
Indy Admirals. You would think, "boring!" but sailboats are not. We run a one-design class for the Victor V-32. Same weight, hull, sail area, etc. Its a good time.

Again, as long as they are evenly matched a lot of the same strategy comes into play as in car racing.
