Found a 5 cc one from O.S. Graupner, maybe who you're thinking of, which runs on nitro fuel. 
I heard mention of a 50cc one, from some guys that make rotary engines for watercraft, but I haven't actually seen it anywhere. And the O.S. Graupner stuff looks pretty old, like antique collector's item type old--I'd only want cheap, used old

the ones i posted still are the smallest.
those are the microscopic rotors, and they ARE microscopic internal combustion rotary engines. each one of those rotors is one millimeter, so it's tinier then even a 1cc engine.

Well, yeah, they're smaller--which makes my question incorrect, I should really be asking what the closest motor to 25cc is. Incidentally, in searching I noticed that the largest rotary engine used natural gas, and actually ended up more efficient than similar-sized piston engines. Interesting, given the current research into natural gas (as well as hydrogen 'n stuff) for eco-friendly cars.

They go for quite a bit on ebay, though. But they always were expensive.

I thought those were plane engines?
