Thrash,
I suspect a Jett .25 or .30, or FORA .29 would be the absolute fastest motors out of the box, but price, complexity, and consistency dictate something a little less exotic for combat. In combat you want to run at the same speeds of others - not be too fast or too slow.
Nope.. Im pretty sure the Novarossi turbo 7 port is THE baddest.. used in CL speed events around the country and will spin a prop in the mid 30k's. will put out close to 2.2hp purely stock and closer to 3hp when tweaked right at close to 37,000 rpm when the prop unloads with the right pipe. As you stated though, probably terrible in RC Combat but would be fun to watch...
