anyone else here using a corvair engine for their LSA?

Rolly LSA (Rolly Clark) was planning to use a Corvair, but I don't know if he comes around too often.

Here are some pictures of my corvair engine. Im waiting on the heads from WW and Flywithspa. I hope they will get here by the end of this month. They are great people to work with but it takes for ever to get anything from them.

If anyone is interested in a corvair engine for your LSA you cant beat William Wynn or flywithspa for information and parts, I highly recommend them and their parts and all the testing William has done on the corvair engine. The reason I went with them was the empirical test data that they have developed on the corvair from testing and flying all their parts.

Dave - what will the engine weigh when finished, and how much do you think it will end up in total cost. My O200 weighed 199 lbs with no exhaust, baffles, or carb heat box. Mark

The weight is the same at the 0200 and you can build a new engine with William Wynne and SPA parts for less then 15000. If you are interested I suggest to check out these two web sites. www.flycorvair.com and www.flywithspa.com

davzLSA,
The red and gold colors look great. What is the displacement of your engine? I'm considering the 2775 kit.
Good luck on your build and keep us posted.

About a year ago I saw a webinar that was about building a corvair engine. It was really neat to watch. They appear to be a nice engine option. My IA friend is really fond of the corvair engine. I looked into them a little after watching the webinar because I plan to build a LSA BH after we get the 4-place done. I determined I could build a stroker C85 for about the same money. I'm admittedly a C85 fanboy but I'm still interested in alternative engine options.

I am curious Dave, what parts are reused when building up one of these engines. I'm assuming the build has to start with a core?

For comparison. On the stroker C85 build we did for our Luscombe we had a new crankshaft, new cylinders/pistons/valve gear, new mags and everything else yellow tagged. After our IA helped us assemble it we had about $10k invested.

HI Guys, my engine is a 3L. The rated horse power for it is 120. You do need a core to start. There are a lot of options to chose from. From the 2,7L up to the 3.1L, The parts in the core are all refurbished. There are certain models of cases and heads that are not use in flight engines. I put new forged ROSS racing pistons and forged rods in my engine. It was a kit that William Wynne and Dan Weismen sells. They also offer other displacements, The original crank is used and I had the 5th bearing put on my crank, The rear engine cover which contains the oil pump is refurbished and made into a high volume oil pump, and the distributor is reused but modified to have 2 sets of points. One set of regular mechanical points and a set of electronic points which is what provides the dual ignition. . I got all my parts from William Wynne at flycorvair.com and from dan weisemen at flywithspa.com. William sells a conversion manual that lays it all out. It goes into great detail on parts, sources and the testing and flying he has done with the parts he developed over the past 25 years. I went with it because for the price of a used continental or lycoming I got a new 120 horse engine that is reliable and I built myself so I know that engine very well. It is a GM product and all American made which makes a difference to me. It uses common part that are inexpensive and can mostly be found at your local auto parts store. Its simple, it uses an aircraft carb and all the parts are aircraft grade. It is been flown in hundreds of airplane with thousands of hours reliably. As you can tell i'm pretty sold on it. I just think it is a great value for the money. But please don't take my word for it, investigate it and make your own opinions.
