Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

I have run it on air. It will run on less then 1 psi. Runs very smooth. For the money yes I would recommend it. They are really nice engines. He makes them with govner and with out. With govner its a S10 with out its a S10B. I like the govner and it is also a functional govner. Not just for looks.
