It’s official! The first plans-built Cracker Jack – built by Gus Geissinger back in the 80s – will be the test aircraft for Pete Plumb’s beta test engine.  First plans built CJ by Gus Geissinger026The aircraft has been kicking around on Barnstormers for about a year now with no takers so we made an offer on the plane.  Kudos go out to Pat Panzera of CONTACT! Magazine for coming up with a workable plan to have the first, and only [that we know of] flyable Cracker Jack Sport come home to its designer, Pete Plumb.  Pat was able to arrange with the current owner of N205CJ to donate the plane to CONTACT! Magazine! With a corresponding donation of a new Pegasus DP-1 to the project , the Magazine will have the only flyable Cracker Jack in the world! Pretty Cool!

Originally powered by a ‘half VW’ built by Gus himself,  Cracker Jack #1 was under-powered; just like the prototype with the 950cc DAF.  “Hanging a 57 horse DP-1 on that plane will really make a nice performing airplane out of it,” Pete said. “The Pegasus is a bit heavier but we can easily work that out.”  As most of you know, Pete has done a complete redesign of the Cracker Jack during the plane’s 30 year hiatus from the Light Sport market and it was this new plane that inspired the design of the Pegasus DP-1.  “Although we are working on building a brand new Crackerjack 2, it won’t be ready to fly until at least next year so this option will get the new engine in the air more quickly and with a lot less effort,” Plumb said.  “We are going to try to get the plane up and running so we can display it at the CONTACT! Magazine sponsored French Valley Fly-in in mid-September.”

Watch for pictures and updates soon!

Note: The two different spellings of “Cracker Jack” and “Crackerjack 2” are intentional.  The new Crackerjack 2 designation will insure no confusion with the trademarked name Cracker Jack tm , a Nestle Company.                                                            PROTOTYPE CRACKER JACK SPORT IN FLIGHTCracker Jack in Flight

    I saw the article in Sport Aviation about your engine. The work you did on the design of the crankshaft was fascinating. I thought I would acquaint you with our deep cryogenic process that we use to treat racing engine components. We have seen up to 5 times engine life under championship racing situations. If you would like to learn more, take a look at our website at http://www.metal-wear.com. Also, we have a shop in North Carolina that caters to the engine building people. They can be more than helpful with engine design and manufacture.
