Congratulations !
A lot of energy, do you think you're going to make an airplane with it?

Very nice. What materials did you use for the piston and sleeve?

Frankly in near future not

Liner is made from scrap mild steel shaft and piston is out of cast iron "puck".

Cast iron pistons in steel cylinders were once the most common model engine materials. The engines that come to mind are the Fox 35 and their combat specials. Others were the early OS Max engines. I think it's still a combination that's easiest to lap into a good fit for model engines. Aluminum pistons in chromed sleeves have replaced the combination in performance engines. Ringed aluminum pistons were an intermediate step.

This engine is my version of these classic stars.

Make drawings are planned, but there is not enough time.
