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

Bonjour,

Charlie, This first test was done with a 2 blades 60 mm offshore propeller, I will try a 67 mm, then I will buy 3 blades 60 and 67 mm ones and measure the results with a, emectronic tachometer.

For my gas fall of pressure issue, I will convert my tank to liquid phase.

My best "ennemy" runs at about 12 km/h, 6,5 knots, this is the speed that I want to exceed as much as possible
