Snowmobile engine for ultralight airplane
I'm looking into puttiong a Wankel or 4 stroke piston sled engine in an ultralight.Does anyone have any experience with the Arctic Cat (or any other) rotary sled engine? Or have an old one for sale? (email me )
Four strokes - any model to stay away from?
Two strokes have a reputation in airplanes for seizing; usually what ahppens is a guy will be in a long descent with the prop windmilling, engine at idle, and the thing seizes because ther'es no lubrication going to the cylinders because there's no fuel. Are there any typical problems that you guys face with 4 strokes in sleds?
4 strokes are kind of new for sleds in the last few years, right? What hp range do they make them ? Do they come with a geared or belted reduction unit for the power output, like the 2 strokes?
