This is not CNC technology; this guy made everything at home on his lathe and drill press. Took 1220 hours (a year and a half?) to make the 261 pieces. Note the end-loaded crankshaft into the block (like an Offy), 12 individual cylinder heads, TINY rods and pistons, dual "underhead" cams with pushrods to rockers in the heads. And, he did break-in runs using an electric drill driving the crankshaft!
Even if you're not an engineer, you'll appreciate this!

That must have taken a LOT of patience

I sometimes wonder if these old world craftsmanship skills are being lost in this new age.

ir runs as a rc engine, no spark but high compressed nitro rc gas.

Looks like compressed air gets the nod. No oil bath, no piston rings, yada yada. Fuel and combustion would not be a good idea.

+1 there!
