3.0L Corvair for Zenith 601XLB, Steve Mason.


Two weeks ago,  Steve Mason made a family trip down to Florida from upstate NY. He brought his Corvair down, so we could run it on my test stand. Its a few casual hours of prep and inspection it was ready to break in. I turned over twice in a second or two, lit right off, and ran flawlessly.



Above, Steve give his best “Captain Morgan” pose, something of a social requirement on public Corvair test runs. This picture was taken right in front of my house, looking north up the runway.



Above is a 14 second engine run Video. Just a little look at a 30 minute test run.  In the first 1/2 hour the primary thing we are after is breaking in the cam correctly. This is done by having ZDDP added to the oil (this comes with my cam kits) and running the motor at 1,800-2,000 rpm.



Above, a bit classier picture of Steve. He built the engine from an SPA “engine in a box” kit.  These kits come with every single piece needed to build and run a Corvair flight engine, including every engine part from my catalog of Corvair parts, plus all the appropriate ones from the SPA Corvair catalog. If you would like more info on price and availability on EIB Corvair kits, call SPA at 904-626-7777.




PS: I have builders at my house, but only by prior arrangement. Once every few months someone tries to stop by uninvited. I take a dim view of this, just the way you would if anyone invited themselves over to you residence. I live in a private residential airpark, and the neighbors are pretty cool about me having guests over and running engines for extended periods, but the are not too keen on uninvited people driving through the airpark in circles looking for my house. I have people over for one on one training, to fabricate special parts or for test runs, but these are all done by prior arrangement, and they are regular work, so they do have labor charges. Anyone inclined to stop by and talk airplanes should just come and find me after hours at Oshkosh.  Thanks in advance for being understanding.

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 www.FlyCorvair.com and in more than 50 magazine articles.
