Terry Hand’s 2700 cc Pietenpol engine – w/Weseman 5th bearing


Below is a good photo of Terry Hand’s Pietenpol engine. It is a 2700 cc Corvair with all of our gold systems, a Weseman 5th bearing, and our new 2400-L ultra light weight starter. ( 2400-L Starter ) Terry took the photo on our front lawn right after a test run on our stand. He came down a few days after Christmas and assembled the engine under my supervision. It ran perfectly. Like many of our builders, Terry has put in a significant effort to put back into the Corvair Movement. He Is the moderator on our new Pietenpol Corvair builder group, ( Piet / Vair internet builders group, started 4/24/15 ) and he has done a lot of behind the scenes work on important projects like arranging support for Spencer Rice, our youngest Corvair builder. ( Spencer Rice’s ‘new’ engine and CC scolarship account ) Opening our shop to him for a few days at the end of the year was a mall gesture of thanks for his work.




Above, Terry’s engine. Can you guess from the Color choice that Terry flew in the Marines? You can click on the photo to see a larger version.


The interesting thing about Terry’s engine is its history: It flew about 100 hours with its original owner. A nice guy, but a poor match for Corvairs (or many other engines) because he didn’t want to do things like set the timing on the engine or follow much of my guidance or read things I wrote. The engine never quit on the guy but he did blow a head gasket, overheat it, and he ran it out of oil, twice,( on the same trip.) Unhappy with the engine he complained about it, ( and only later realized this undermined his ability to sell it.) I offered to assist him to correct the damage, but he declined, thinking that the problem was with the engine, not the operation. A few months later he sold the engine to Terry for a fraction of what he had in it, a fair value for an unloved engine, not running with a blown head gasket.  A few days of work, about $1,600 in repair parts and upgrades, and Terry now has the engine that will power his Pietenpol for years of reliable service. The difference? Terry understands that the issue was all in the mindset of the builder, and had nothing to do with the engine.


Here is a link to a one minute video of the engine running on the test stand:





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