18CV-R power plants deliver “outlaw” output — 11% more performance than a .15, in the same mounting space! With big-bore carbs for more hole-shot power, super-durable machined steel pistons and oversized, 11-fin aluminum heads, they’re ready to lead 1/10 scale racers to the winner’s circle. Available in versions with 11G slide-valve and 11J rotary carbs, with or without recoil starter. All engines require a muffler or tuned pipe and header.
