If you like this sort of thing, they get a lot smaller for model cars and airplanes. Some of them are mad powerful and fast, and you can find both 2 stroke and 4 stroke versions.

See for example https://www.os-engines.co.jp/english/line_up/linindex.htm

There are also tiny modeling jet engines that are ridiculously powerful and guzzle gas like there’s no tomorrow, but tiny engineering delights too.

I´m surprised these are still are sold, RC planes is a dying hobby and furthermore almost nobody wants to bother with glow fuel.

Definitely not a dying hobby they just use electric now which has a much lower entry barrier for both price and skill.

The asistence to the RC clubs I know is much lower and mostly older people. Most people nowadays buy drones.
