I'm thinking of going with a 0-200 engine and wanted to know.

What additional bracing or structure is needed when using a heavier engine. I think some of you guys with the Corvair are about the same weight. The plans say 195 I think but I know there are alot of installs out there over this. I really would like to go with an aircraft engine if possible, even though there are some really good conversions out there.

I would greatly appreciate any advice

I have also a question regarding this:

What type of O-200 to use? Are there any edition that we should walk away from? I always imagined going with a Rotax or Jabiru, but that's just going to be too expensive.

When I wrote Chris a letter about the fact that I WAS using the Corvair and did I need to hire him or another aero engineer to look over the front of the 701 for areas of concern, his written reply was "use the Corvair, no modifications necessary".
It's in the archives. As you state, the weight of the Vair and 0-200 are identical,, if you want to get serious about weight on the certified engines you might look into the C-90 , same displacement as the 0-200 but a few pounds lighter. Chased all that down a few yrs ago but memory has faded.

Hans,

You might want to consider doing a WW Corvair Conversion. The cost will be about 1/3 that of a new Rotax or Jabiru (if not more) and it will be an engine you can maintain yourself. William Wynne is out of Orange Park Florida and has been helping quite a huge movement of builders to convert the Corvair engine into a 100 HP air cooled, 6 cylinder engine. He does offer to build an engine up for you if you don't want to do it yourself. Here is his website: www.flycorvair.com

Larry,

FYI, William Wynne no longer builds engines for sale. I think that Kevin Fahy (of the former WW "Hanger Gang") now offers that function. The only way I know to contact him is through Gus Warren (flywithgus.com).

John B:

Would you care to share the correspondence you had with Chris H. around the acceptability of the Corvair engine in the 701? You say it's archived. How may I access it?

Thanks
