Brian, You asked me about the strut fairing on the CH-801 that I built, the fairings came with the kit, offhand I don't recall if they were an add on or came with the standard kit, but they did come from Zenith.
I felt it needed a fuel pump , min fuel and high angle the flow was not very good and I thought the little electric boost pump would be good insurance. As for performace,it was not bad for a heavier engine. I have flow a lot of rotax and was really surprised by how good it could perform I think. A lot has to do with the whirlwind prop . You don't feel the steep climb out that you would with a rotax but it's not bad
I think the corvair is heavier than the 0-200 and you might have trouble keeping the thing cool , the STOL only flys at about 80-85 MPH
Although I have only taxied so far the corvair has worked out ok. Had a couple issues mostly because of having no experience with the Aerocarb I am using, there is quite a learning curve associated with it. I have contacted the FAA MIDO office locally and will be getting an airworthiness inspection with the next 2 to 3 weeks if it goes as planned. First flight will come very shortly after.
I wish you successful building. Stay at it. Do something every day to advance the project.
My first pneumatic riveter I got on ebay, it has since broken. I now have a red one purchased at Angelo Bolt in San Angelo, TX. The nose piece I dished with a dremel tool and a round grinding bit. Some of the nose pieces are too hard to grind. Found my hand riveter used the same hose pieces.
Found a corvair engine on barnstormers 80% converted. Headed to Mexico, MO later this week for Corvair College and Zenith open house.
I have an original (unsplit) nosebowl from William Wynne that I will be using on my Corvair powered Cruizer. Remainder of cowling will be the standard, tried and true, aluminum construction used on most all Corvair powered Zeniths.
