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.

For those of you who missed the Aug. meeting you missed a good one. We had over 65 folks present which made for a wonderful meeting. The highlight was a presentation by Jon Dauplaise who flew in from Duluth (the Norwegian Riviera) in an SR22, the all glass cockpit aircraft from Cir-rus. There is talk that maybe this fall or winter the chapter could get a bus and head to Duluth and tour the Cirrus plant for a day.

We had about a half dozen new aviators show up at the meeting as they had heard about our chapter and they were checking us out. It looks like they enjoyed the activities and talking to our members, because most of them have already joined. You guys and gals are doing a good job getting the word out and bringing in new members each month. Please keep up the good work.

Peter Denny and his Washburn High School students are just getting back into the swing of things as I write this column. Building the Sonex is going to be great fun. Pe-ter wants our membership to keep an eye on the Sonex, but he also has so much more available at the school that he would like to see our chapter take advantage of. He has a couple of engine cores from Darrell Bolduc that could be used for an engine rebuild class, or he could run a fabric covering class. Some of our CFI’s could give his flying students some IFR training on their desktop simulators. ect.etc.etc… I need your input on what you would enjoy doing. Talk to me or any of the officers via phone or email and let us know what you are thinking, or stop by and check on the Sonex and talk to Peter.

I want to keep things fun, interesting and educational, but I need to hear from you!!!! I can’t read your mind. Heck, I can’t even read my own mind sometimes. “ Talk to me Goose” —Pat

Super Hatz Classic #1—See it at Airlake 9/17

ON FINAL SEPTEMBER 2003 4

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 CB1 to fly behind a 90 to 100 horsepower engine, with the cylinders exposed like a J-3 Cub. Twenty nine years later, in 1997, Billy Dawson completed the first Hatz Classic, a some-what larger and more comfortable version of the Hatz CB1. Billy replaced the cables for the ailerons and elevator with push rod and bearing controls, leaving cables only for the rudder. He rounded out the flat fuselage design for a differ-ent look. For more room, he lengthened it by 4-6 inches, tilted the seats back and moved the rudder pedals forward. For more power, Billy chose the O-320, and changed the cowl for a full enclosure. All of this changed the look of the CB1 quite a bit, and corrected all the things Billy found he didn’t like on the CB1’s he had built before. Billy won Grand Champion for his blue and cream Hatz Classic at Osh-kosh in 1997, and this was the biplane that inspired me.

The World’s 1st Super Hatz Classic I call mine the Super Hatz Classic, because I went with the O360 for an additional 20 horsepower. I moved up from the 7456 or 7458 prop typically used with the O320 to the 7658 for the O360 (76” length, 58 pitch.) The 360 weighs only 7 lbs. more than the 320, so the weight and balance was not af-fected. I get 2700 static rpm and 2500 on climbout. Red line is 2700. The tail number is NX601HC. People ask how I chose that number – this is the 6th Hatz Classic flying, and the 01 is for the first Super Hatz.

Plans-built without plans When I started on the Hatz Classic in October of ’97, the only plans available were for the Hatz CB1. I paid $125 for these from the Hatz club, but they included none of the changes for the Classic. Jeff Shoemake originally worked with Billy Dawson on the jigging for the round fuselage and they began to draw up plans for the Classic during the period I built mine. So I spent a lot of time on the phone asking questions, and they sent copies of plans for different parts as they be-came available. Of course those didn’t include the changes I

by Dennis Simmons ( see cover )

made to get it just the way I wanted it.

New features of the Super Hatz Classic ◊ O360 180 horsepower engine ◊ 7658 prop ◊ Four-to-one tuned exhaust, made up by a company in

northern Wisconsin ◊ Modified cowl for engine and exhaust ◊ Replaced carburetor with Elison throttle body for

more power and lower fuel consumption ◊ Metalized covering on landing gear like the YMF5

Waco to avoid cracking typical with fabric ◊ Removable metal belly pan instead of fabric—easier

to keep clean and can be easily removed for repairs or just to retrieve things dropped into the fuselage

◊ Added front glove compartment ◊ Added rear storage compartment under the turtle deck,

just long enough for my arm reach, accessed through a half-moon door above the seat

◊ Added fore and aft cabin heat for winter flying

Fabric System I chose ceconite fabric along with Randolph’s Ranthane sys-tem of traditional dope with the polyurethane finish.

Tech Counselor Chapter 25’s Earl Adams served as tech counselor.

Certified for Aerobatics During the first 25 hours, you must perform all of the aero-batic maneuvers for which you want the plane certified. Brian Jenson, who flies his Laser out of Airlake, performed all the standard maneuvers for me.

evening. I was most impressed by the pro-fessional demeanor, k n o w l e d g e , a n d friendliness of the vol-unteers serving that evening. As one who loves aviation and the Wright Flyer and all it represents, I could not help but feel proud as I watched the volun-teers at work.

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.

Whether aviation enthusi-asts or not, the crowds could not fail to be im-pressed by the quality workmanship and faithful reproduction of the 1903 Flyer. Those who con-tributed the long hours to construct the replica, in-cluding Chapter 25 mem-bers Dale Johnson, Steve Adkins, and Dick Burns, have every right to be proud of their creation.

The large east atrium seemed designed to show off the flyer to best advantage. It was large enough to accommodate the full-size rep-lica, leaving enough room for shoppers to see the Flyer from all di-rections as well as stop and visit with volunteers as they passed through. Yet it was also small enough that the Flyer filled the

space and appeared to be almost larger than life.

The volunteer groups completed the setting with plentiful materials stacked neatly on tables behind the Flyer, with volunteers well placed to answer shoppers’ questions as they stopped to inspect the replica. I visited the mall on a weekday eve-ning when the mall crowds were thinning out, yet a steady stream of visitors kept the vol-unteers busy the entire

“It is only with the heart that one can see rightly; what is essential is invisible to the eye.” -Antoine de Saint-Exupéry, The Little Prince

Over the past nineteen years of familiarity with an IO470-J engine in the family Debonair, we have always tried to avoid hot starts. They have been problematic at best! Comparing the published material in the Beech pilot handbook vs. what Continental manuals proclaim, you find two different proce-dures. Searching the web, and/or referencing the American Bonanza Society (ABS) materials does not bring any further clarity to this issue.

It's been my personal experience that each of methods has mixed results in varying climatic conditions. That is to say, how hot (and humid) is the environment? Sometimes each of the varying methods shows promise, and results in a per-fectly clear running powerplant. However, recently one eve-ning after a short flight the aircraft sat for an hour in 90 de-gree temperatures with a dewpoint of nearly 75 degrees (which is tropical, and rather rare here in Minnesota) and vir-tually no wind.

First order of business, was thank goodness for a strong bat-tery! I proceeded in frustration to no avail, having attempted every method published within the POH, and from previous experiences. All attempts resulted in flooding the engine. Fellow Beechcraft owner/pilot Ed Fischer came to my rescue this evening. We let the aircraft sit with the cowl open for about 30 minutes. Then applying Ed's method of hot starting his IO-470 powered V35, the Debonair fired to a resounding purr...

After several subsequent hot starts over the past couple of weeks, I have fully accepted this new method.

1. PROP: HIGH RPM 2. THROTTLE: OPEN ONE TURN 3. IGNITION: BOTH 4. PRIMER: SHORT SHOT-JUST TO GET IT RISING 5. THROTTLE: 2/3-3/4 OPEN 6. STARTER ENGAGED

LET IT TURN UNTIL IT STARTS, BE READY TO COME BACK ON THE THROTTLE TO IDLE & POTENTIALLY GIVE SHORT BOOST PUMP ON/OFF.

One closing comment. Much has been written about low winged aircraft with injected fuel systems and the resultant need to overcome vapor lock by circulating the fuel to get cooler fuel into the cowl. This may be performed (if neces-sary, or even if not sure...) but it's what’s done after this pro-cedure that may result in continually flooding the engine.

Ed, thanks for the help. —Frank

Safety Wire Tool by Don Sektnan

Here is a simple safety wire tool that can be made from a screw driver. Ei-ther a blade or cross point screw driver will do just fine. A round shank screw driver is preferable. Grind off the end square. File two notches on the shank approximately 3/32 in. from the end and with one side parallel with the end. Drill two holes through this section just large enough to pass the safety wire through, either .032 or .041. Do not drill into the sloping wall of the screw driver shaft. Now it’s ready to use. Cut the wire to length. Route the safety wire through the item to be held in place, routing the ends back through the two holes in the end of the tool, work-ing the tool up close to the item to be held. Judge the distance between the two attachment points so you know the length to twist and spin the tool. Makes smooth consistant turns and makes good use of an old junk screw driver.

Mark came, Frank Hanish arrived in his Deb. We had a large ratio of ground crew to Young Eagles as we almost had 1 ground crew member for each Young Eagle. And smooth, eve-rything went Smoooooth! Thanks Jeff, John and Ron for the ground help. We flew 5 Young Eagles that graduated from a St. Thomas engineering STEPS program which teaches the students the principles of science and physics. 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. Our Chapter members from the Cambridge area are going to talk to some groups in the area also, so we are expecting a large turn out. If you can help with this event please let me know. We will try to pair up ground help with pilots that will be going up to Cambridge to

fly the Young Eagles, so we need to know of your support early. —Mike
