Why are low-revving, high torque engines preferred?

I've never heard that, seems unlikely... they are really very different, except for both (along with outboard motors) being 2-strokes. All for the same reason of light weight. -Dana Some of the first ultralights DID run chainsaw motors - just like the go-cart crowd. Some of the small aircooled outboard engines were also used - and some early snowmobiles also used a converted aircooled outboard. (horizontal twin Johnson Snow Cruiser and OMC) I seem to recall that my first powered ultralight was an Easy Riser powered by a 10 HP West Bend Chain Saw engine with a belt reduction made and marketed by our own Chuck Slusarcyk. :-) Highflyer Highflight Aviation Services Pinckneyville Airport ( PJY ) |
