At Oshkosh this year I spent a decent amount of time listening to William Wynne preach the religion that is, "Fly Corvair."

I've talked to Zenith, Skycoupe, Pietenpol, etc. owners who have up to 1,200 hours on their convair engines (the 1175 hour engine has been flying for over 20 years). I feel they've been well proven in airplanes over the past 40 years.

Would a 100hp@3,150rpm (90hp continuous@3,000rpm), 160ft/lbs@2800rpm, 5.6gph, 225lb, 28"l x 28.5"w engine be a good match for an LW-5?

A professionally built Corvair engine would cost $6,750.00 (it could be privately built for less than half of that, but I'd probably just pay so I knew it was done right).

Details on Corvair engine conversions are at William Wynne's website: FlyCorvair.com (http://www.flycorvair.com/).

Opinions, thoughts, ideas?

The one downside I see is the relatively high rpm combined with no reduction drive means you'll be turning a smaller prop than most other engines options for the LW. That's usually not a good thing in the speed range we're talking about here...

I have one converted if you want it. $4500. The 69" prop was used on fixed wings that had a max speed of 90. and stay at 70 MPH all day. 2600 rpm is not high at all and 69" prop is not small. I need to sell this to get another gyro. But if not sold you will see it fly on a gyro later.

I have a stock Corvair Spyder engine in my hangar that I was planning on converting and would like to contact someone who has already been through the conversion process. Thanks.

I did with the manual William Wynne sold me. Lot of his parts are on mine.
