The Corvair folks (including three that are flying now, Makish, Lester, and Clapp) are using an engine mount that puts the thrust line 2.375" below the longeron, and it seems to work fine. I think I've seen something very close to that in an old Newsletter, but most references point to the longeron line as the thrust line. Apparently either one works fine, so you're in the ballpark. The DAR comes today (he's up here signing off an RV and a Baby Lakes anyway), but after a frenzied attempt to get ready, there's no way in the world he's going to sign me off today. There are way too many things to do before it's airworthy (which is not news to me, but I needed a reality check to make me realize it's not going to happen today)...
