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

The pressure is probably accurate. With the air you have a much larger supply to maintain the pressure. The pressure with steam will balance out when the use and steam production become equal. I lusted after one of those for a long time and it turned out to be a huge disappointment. Under a load mine would literally freeze up after running a little while. I was so happy the day that I got it and even happier the day that I sold it!
