Welcome to FlyCorvair!


After three decade’s worth of new experience, information, flight testing, and fun my mission is the same as it was on Day One: Provide a reliable, affordable engine for homebuilt aircraft.  At the very core of this is my belief that aviation is not a spectator sport. I’m personally in aviation to do it myself.  Chances are, you feel the exact same way.  We all share the common bond of being in aviation as a participant, craftsman, and creator. If this sounds like you, don’t be surprised. The need to build and fly your own machine is as old as the Wright brothers and will always be the core of aviation.

Welcome to your home in homebuilt aviation.


What our Customers are Saying

Kevin and Shelley Purtee


I’ve been flying professionally for more than 30 years. I’ve been an active homebuilder for most of that time. William Wynne has taught me more about homebuilts, small aircraft design and construction, aviation risk management and aviation engines than any other single person. I’ve been a customer and student since 1999. My wife, Shelley, and I continue to rely on William for the engines we use in our aircraft.

Larry Nelson

Zenith 601 HDS

Corvair Engine Builder since 2015. My day job is testing military equipment, and as such I appreciate systems that are based on a proven track record, and follow proven methodologies.  In my search for an engine, what struck me about the WW Corvair was the similarity to how Lycoming and Continental test and train people to maintain those systems.  That alone puts the engine in a league of it’s own.  As a corvair builder you learn more about your powerplant than every other system available on the market.  This follows the EAA moto of Learn, Build and Fly.
