I have a couple of good type 4 motors laying around. I was thinking it would be fun to build a prop driven snowmobile like a swamp boat. Anyone know where can get a prop? No I haven't googled the thing.

Aircraft props are optimized for about 2000 RPM operation. Aircraft that use automotive engines usually run gear-reduction boxes to allow the prop's optimal RPM (about 2000-2500, maybe) to occur near the engine's peak power RPM.
You can sometimes find AC props that have "aged out"--they seem structurally good, but have been in use long enough that the FAA won't let them be used any more. You might have better luck with some sort of ducted fan setup--though I don't know where you'd find that for cheap. --DD |

I had similar thoughts years ago after seeing a picture of a "snowplane" in the back of a woodworking magazine. Apparently they used bent hickory or ash to make the skis. It might be cool to cut up a bug and use as a fuselage. I hope you do it.

Speaking as both a pilot and snomobile rider I think you'd have more success building a snow-vehicle that put the power to the ground vs. using a prop (unless it's really flat where you live and the snow is never sticky).

Just thinking out loud now. (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif) Like I really have time. I haven't been home for a week in the last two months. (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) Maybe I should get a life first. (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif)

The combined brain power here is 100 times the ability of the Cray.. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) You can ask most anything and get real world experience answers. Way better than google.
