12 Cylinders / 6.0L of Corvair Power for JAG-2 run at CC#31

Builders:

If you read this site regularly, you have already heard of Jim and Ginger Tomaszewski’s twin project, the JAG-2. They finished both engines for it at Corvair College#31, and we got both of them on the run stand on Sunday for 30 minutes each. They ran flawlessly.

.

You can see photos of the nearly done plane at this link: New Photos of JAG-2, a Corvair powered twin. and you can read a longer story on the development of the plane in Jim’s words at this link: JAG-2, Corvair Powered Twin, Jim Tomaszewski, N.Y.

.

Without fail, when the topic of this plane comes up, someone will chime in to say that flying a twin requires a special rating and twins have a poor safety record when flown by amateurs with the wealth to buy them but not the skill to operate them. These statements are true, but they do not apply to Jim.

.

He is a low-time single engine pilot with 500 hours, but he is a high time multi pilot with more than 15,000 hours in planes with more than one engine. You would think people might pick up on this as Jim’s Email address is ‘DC-8Jim’, but they often do not. Much of Jim’s time is global corporate flying, often to very challenging destinations. Ask any honest ATP and they will tell you that very few airline destinations require the skill of a night landing in a corporate jet at Aspen Colorado.

Above, both engines on the bench. These are first class 3,000 cc Corvairs. They have Weseman Billet cranks (https://flywithspa.com/product-category/corvair/) and all our Gold system parts. (these were painted by Jim to suit his taste).  Note that both engines are equipped with our new Ultra light weight Starter assemblies, part number 2400L. These engines are essentially clones of the one on Dan Wesemans Panther, (although most pictures show the Panther engine with our standard starter, it has been flying on a 2400L since the spring.) For a look at the logic behind that engine, read this story:Why Not the Panther engine?

Above, both engine in process with Jim and Ginger on the right. They ordered  #2000HV cases before the event and picked them up in person, they took only a 30 minutes each to install. The engine oil fillers are on the top covers because the narrow twin cowls do not have the space on the sides like single engine cowls do. Both engines have group #2800 oil systems and rear alternators.

 Above, the second engine runs at the college. Jim said his time line is to fly the twin back to Barnwell next year, fully flight tested and proven. A great number of Corvair builders will rightfully hail him on that day, as a champion of homebuilding and as a builder who was willing to put in the had work to do something extraordinary in aviation.-ww.

Special Note to RV Builders: The section of the Van’s Airforce discussion group that showed just a few pictures and short descriptions of this aircraft generated thousands of hits before their list moderator banned the photos and deleted references to it, and put up his own negative comment. That list is operated as a commercial venture by Doug Reeves, a controversial personality who promotes a very conformist model of homebuilding and flying. He will delete your posts if they reference things he dislikes, often as simple as making a low pass. 

.

In a single week, the tracking on our site showed that 220 RV builders on that site followed a link to come here and read my story 2,500 words about levels of aircraft finish… Reeves also deleted all of the links to that story to block RV builders from even referencing it. It was deemed too controversial because it included the single sentence “We were not the ones who decided that regular looking people and the planes they built were not cool enough to be on the cover of their own membership magazine. That one is on the Editors and the management of the EAA…” To my perspective, Reeves is a throwback to the type of aviation magazine editors of the 1980s and ’90s who worked to make sure only people they “approved of’” felt welcome in experimental aviation. RV builders are often unfairly characterized as uncreative conformists. Reeves’ actions unfortunately reinforce this stereotype. RV builders with open minds are welcome to come here and directly read unfiltered ideas.  -ww

 

 

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.

    do those twin engines both revolve the same way or has one been reversed ?
