Billy from Philly, 3.3L Corvair engine run video


Billy Kerchner, a Sonex plans builder from Philadelphia, was one of the other builders who came to my hangar for the finishing school.  He also elected to build an SPA 3.3L Corvair from an “Engine in a Box” kit.  We caught this short video after the run, when he was packing unto head home.  Not technical, just capturing the spirit of the moment. Word of caution to viewers under 13 and the easily offended, video does contain an accurate expression of happiness in the true Philly vernacular.



We just reached 1,000 subscribers to my Youtube channel yesterday, but your participation is still important, if you have not yet subscribed, please take a moment to do so. Thank You,



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.
