The world's tiniest V12 engine. [VIDEO]

JFP, I sent you a PM with a question, in case you have a minute to help me with a question

thanks

Very cool model. I'm not sure it's really firing. Raises some questions:

Splash lubricated crank? No oil pump for heads? Coolant radiator?

I used to build and fly single-cylinder, diesel-powered model airplanes and those heads got really hot. The air-cooling was marginally effective.

Pretee cool to see. Funny when he gets the mechanical vernier out to measure, humble cool dude lolll

Fact is this guy had to use precision measuring tools, read digital/calibrated, for most of these small parts, if not for all of them lolll. No probes on those little benchtop machine-tools, all gotta be measure on the machine itself/by hands (ouch) 1200hrs.. wow

Always wanted to get something in those sizes going myself. The 1200hrs never been too attractive gotta say. Never gonna happen and pretty sad about that

If I ever get that time I might be aiming a tad more abstract however; something like that (with micro-servos and a thumb-size microprocessor, of course!)

No overhead cams? Hrmph.... Might as well buy my hamster a Mustang.

Seriously though, very cool, and reminds me of this:
