I think just about anybody short of a moron is "qualified" to build a Corvair conversion engine. If you buy William Wynne's $59 conversion manual, combined with the $15 GM factory manual, you are immediately armed with all the information you'll need to build a safe Corvair airplane engine. The few tools that you don't have can be bought inexpensively or even rented. As a long-time VW mechanic, I'll be quick to tell you that the Corvair is even easier to rebuild or do maintenance on than a VW. There's a cover on top that you can remove to gain full access to the crank and rods. VW's could only dream of that kind of accessibility. And if you need professional help building your Corvair engine, just take your core and your pile of new parts to one of the many Corvair Colleges that William Wynne holds for FREE all over the country and let him and his crew look over your shoulder as you build it!
For more info on the Corvair engine, see http://home.hiwaay.net/~langford/corvair/ and http://www.flycorvair.com/ . I'm convinced that this is by far the least expensive, yet still reliable, airplane engines in the 100-130hp range. And the six cylinders is something that you don't get with a VW. You can lose one whole cylinder and hardly notice the difference... Mark Langford, Huntsville, AL N56ML at hiwaay.net see KR2S project N56ML at http://home.hiwaay.net/~langford
