The little MVVS's are good value... but they're not "racing" engines. Sure, they like to rev, like most small engines, but not like a true speed engine. They need modifications for some real performance.
The little Nova Rossi's are basically car engines with some modifications to make them suited to turn a prop. So they sure like rpm. The problem here is finding a prop. You will most likely have to start making them yourself...
Oh, and they are worth about their weigh in gold
VERY expensive. They have .21's that cost about 500 euro's...
