Mr brother used to fly those little u-control plane with tiny gas engines....damn things would almost take your fingers off trying to start them. :willy:

All those pistons just a workin' and a workin'....

To me the ones that count are the ones that actually produce their own power.

There was one in there that was run from a compressor. It wasn't really doing anything, the compressor was just spinning parts on it. The compressor was the powerplant, not the engine.
The rest in that video looked liked they actually worked and produced power.

The smallest ones I remember were the .020's. That's 2/100ths cubic inch displacement. I put one of those on a free flight plane that I built. Had ribbed wings with paper/dope covering and a solid thin body. I added an external fuel tank to the tiny tank that was part of the engine, giving it about 4 oz. capacity. Trimmed it so it would circle as it flew (so I could get it after I launched it.) Miscalculated on that bit. The last I saw it, it had climbed to at least 2,000 feet. You could still barely hear it for about a minute later as it continued to climb until the sound was too faint to hear. Never found the plane. Some say it's still climbing til this very day.
