Behind the scenes work.



Even when I don’t write blog stories, activity in the hangar still rolls along. 2018 was Oshkosh number twenty three for me, and I collected a good number of stories that I will share a bit later. The prep work for the event goes on for months, and after it is all over and we pack up and drive home, August is typically a slow month for stories, but the work and parts production, and the prep for the fall events at the Zenith Factory and Barnwell SC still advances.



Above; A large shipment of CNC mandrel bent stainless tubing for Intakes and Exhaust systems arrives after Oshkosh. You are looking at $5,000 in tubing; It is made in the US, from US material. I get offers from Chinese companies every month to supply this tubing for a small fraction of this cost, but I operate on the assumption that our builders prefer I use the best material rather than the cheapest. I have had the same supplier make these for more than 20 years. It is the same outfit that supplies the OEM parts for Lycoming and Continental.  Many of the tubes pictured are already finished product in the hands of builders around the country.


This week brings more prep work for Corvair College #42 at the Zenith Factory in Mexico MO, September 21-22.  I share more information on it over then next few days. The center piece of the event will be the assembly and test run of a complete 2,775 cc Corvair engine with a billet crankshaft, from an SPA “Engine in a Box” complete kit. The engine is not spoken for yet, and if you wish to be its owner, contact us for more information.

About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at and in more than 50 magazine articles.
