Frank Hanish & young eagles Young Eagles at Airlake by Mike Dolan A mini Young Eagle rally can be just as much fun for all who are in- volved as the larger ones. The smiles on the new Young Eagles are all the same size anyhow, HUGE! Saturday, August 30th brought the best of the best as far as VFR flying is concerned. Mark Kolesar arrived at the Chapter hangar in his A36 Bonanza raring to start flying Young Eagles and he ex- claimed "Something must be wrong today. I didn't hit a bump all the way down here." It was that nice. Soon after (Continued on page 7)

The night of Sept. 17th is shaping up to be another excit- ing night at our hanger. We have Dennis Simmons lined up to bring his award winning Hatz (Reserve Grand Champion plans-built) aircraft to the hanger for a static display and presentation. It is also the monthly meeting at which we will draw the winner of the Ford pickup lease that Mark Gul- brandson has donated.

If you have tickets and money to turn in, make sure you make it to the hanger as early as possible on the 17th. There will be a lot going on with the raffle, individual annual membership renewal, and tickets for the Nov. 16th award dinner/banquet on sale. If you are unable to make it and have money and tickets to return, please get a hold of me or another member and get the material to them before the 17th.

ON FINAL SEPTEMBER 2003 3 Super Hatz Classic #1—See it at Airlake 9/17 by Dennis Simmons ( see cover )

My love affair with the Hatz began when I first saw Billy Dawson’s Grand Champion Classic at Oshkosh in 1997. I decided then to build a Hatz, and by October I had already started. That was almost six years ago, and a lot has hap- pened since then. Now I have a finished airplane, and al- though it is faithful to Billy’s design overall, I ended up mak- ing a lot of changes to get it exactly as I wanted it. Since the first flight on June 19th, I have put 50.3 hours on it (as of 9/7), and I can say that it flies beautifully in every way. But to appreciate what I’m flying, you have to know a little about the history of the Hatz biplane.

Origin of the Hatz Classic The original Hatz CB1 was designed by John Hatz in 1968 as a 4/5 scale version of the RNF Waco biplane. John couldn’t afford a Waco, so decided to build his own. He designed the made to get it just the way I wanted it. CB1 to fly behind a 90 to 100 horsepower engine, with the cylinders exposed like a J-3 Cub.

ON FINAL SEPTEMBER 2003 4 1903 Wright Flyer Replica

at Mall of America by Pete Gavin

Volunteers from a broad spectrum of aviation groups joined forces recently to present the best of aviation to an international au- dience. Under the sponsorship of the Minnesota Flight Expo, this group hosted a public display of the Expo’s 1903 Wright Flyer rep- lica at the Mall of America from August 22nd through August 29th. The replica itself was the main attraction, and its sheer size and beauty attracted mall shoppers to the east atrium where it was on display. Volunteers presented information and answered questions about the Flyer itself and also about the numerous aviation organi- zations participating in the event.

Part of this cur- riculum includes the science of flight. Because our chapter is involved with the EAA Young Eagles program these students were able to experience what they learned in the classroom.

Our next Young Eagle event will take place on October 4th at the Cambridge, Minnesota Airport. This event will be adver- tised in the Cambridge newspaper and posters will be in doz- ens of the communities establishments.
