The golden years of experimental aviation reached it's peak (probably in the sixties and seventies) and went into a steep decline, which is now reflected in the false illusion that safety is achievable only by using factory built parts.I wasn't a builder then, but you can imagine a lone figure toiling in his garage on a project, with no Internet, no builder forums, few good reference books, but a lot of ingenuity and common sense. Those days are long gone. Many pilots will just shell out the ninety grand for a factory built sport plane and leave the building to the few true experimenters who love to create. There's nothing wrong with that approach but don't try to stifle the enthusiasm of the guy who wants to try to build his own dream with limited resources but a lot of heart.

When many in my fathers generation dreamed of home ownership they bought a piece of land, and took shovel to dirt and started building. Now we're told you have to have an Architecual drawing, soil analysis by a professional and a certified landscape company to plant your grass, and whatever you do, don't try to do your own interior decorating, the paint fumes may explode!

This afternoon we should all tip our glass to the guys that went before and flew that creation with the model "A" engine sputtering while spinning that homemade wood prop!

But those that go about designing such conversions need to either have at least some experience with aircraft power plants or a real strong background in engineering.

I disagree, trial and   error teaches many things. And it would be great to see   this 150 HP in  an aircraft. Quite a lot   is already known   about conversions and   heck, a redrive  is the same   thing in principle  as the jackshaft I  installed on a Bonaza mini bike toaccomadate   the Hodaka Ace 90 that was replacing the Mac 9.
This Yamaha 4 stroke seems to me a  good place to start   if one was   so inclined.

Many a failed attempt at something quite  often turns out be quite an educational experience.

You can go to any snowmobile dealer and buy just the engine, It will be new and ALOT cheaper then the whole sled. We do it all the time when building custom snowmobiles, We make Pol Tax's. Pol Cats Yama Doos and a combination of other creations.

The main reason I would buy a new snowmobile is because I know I would have every part I need except the PRSU. Exhaust parts, radiator and more. When you don't know exactly what you need, those little things will nickel and dime you to death. And I doubt I could buy too many wrecked parts around here, in fact I've never seen a snowmobile in Arkansas. We have a whole lot of those skidoos and alike, but I think their cooling system is too different.

The only real down side to most conversions that no one has mentioned is insurance. You can't get it with an unapproved engine. It's a big risk. I found that out when I tried to insure my skyhawg.

Anybody out there think there might be a market for a airboat with a Harley on it? LRM www.skyhawg.com
