JAG-2 Corvair Twin, running on film


I got a quick note and a link to this video from Jim Tomaszewski, about the first engine run on the wing of his Corvair powered twin, The “JAG-2” :


“Hi William & Grace (ScoobE too), Here is a video of my first engine run of my

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 30 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at www.FlyCorvair.com and in more than 50 magazine articles.

    This is a truly impressive undertaking. I have been checking around the web for updates periodically. I wish him all the best and await the first flight.

    Way to go Jim! One can almost hear the roar of the two corvairs in tight formation slicing up the wild blue yonder, with a perfect sunset unable to escape their relentless pursuit.

    Can’t wait to see this one go uppity up up 🙂 and I look forward to the full report when the time is right. I will be sure to have my paparazzi camera and questions ready.
