Heldmyer, e-mail, 13.08.2010 04:03 "Opposed-piston single cylinder air cooled two-stroke Beltrame engine"... Does ANYONE have ANYTHING on this concept? I know Fairbanks-Morse does it for large diesels for submarines (WWII) and gensets and trains even today, but a small engine like that? It must have been very light!

Ralph Gallagher, 03.11.2009 04:12 built in 1937 by Quinto Beltrame. 1938 edition of Jane's states plywood monocoque, 18 hp opposed-piston single cylinder air cooled two-stroke Beltrame engine, three drive belts to prop. 6.06 m span, 3.55 m long, 1 m high. 4.5 sq m. wing. empty 70 kg, loaded 160 kg. 60 km/h mimimum speed, 140 km/h cruise, 160 km/h max. Take off run 125 m, landing 50 m. range 500 km. elevator is sole. Elevator is only controllable surface: +12.5 degrees, - 2.5 degrees, 30 degrees lateral tilt each side.
