Cool! I like it a lot myself, i'm very happy that you like it too !
Is someone know if that design was used on real thing or if it is only an engineer/hobbyist affair ?
There's one at a show I go to every year and I love watching it, but your slow-motion video made it even better
I have always liked these engines.
It isn't very easy to find a good one for sale like you have shown above. Many will not run.
It is a 6 cylinder engine with only 5 moving parts..!
Very clever design.
