Not too long ago I saw an advertisement for a "truck".... it had a new breed of engine in it... a .46 that produced 5.0 hp at 23000 rpm... they must be running tetranitromethane through that thing.
Now, you won't hear me saying that 5 hp can't be had from that engine... I just want to see it do that for 5 seconds at a stretch.
In other words: there are .21 engines out there that will put out a genuine 2.7 hp... at +40K rpm.
IMO the 2x1 prop suggestion isn't too far off. When you're finished shaving the head down, you'll have to put on a prop so small it will barely be enough to cool the engine.
Molten pistons will be your share
