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

PM Research has one that is rated at 10 VDC @ 1A. Nice industrial look to it. Needs a large engine to power it to its max.

I have 2 of those. I machined the first one and decided it was worth the extra $$ to buy the next one ready to run. They work well, but I have never really done a load test.
