Young Eagles at Airlake
Frank Hanish & young eagles
by Mike Dolan
A mini Young Eagle rally can be just as much fun for all who are involved 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 exclaimed "Something must be wrong today. I didn't hit a bump all the way
down here." It was that nice. Soon after

by Pat Halligan
The night of Sept. 17
th
is shaping up to be another exciting 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 Gulbrandson 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 Cirrus. 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. Peter 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.

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 happened since then. Now I have a finished airplane, and although it is faithful to Billy’s design overall, I ended up making 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 somewhat 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 different 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 Oshkosh 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 affected. 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 became available. Of course those didn’t include the changes I
ON FINAL SEPTEMBER 2003
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 system 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 aerobatic maneuvers for which you want the plane certified. Brian
Jenson, who flies his Laser out of Airlake, performed all the
standard maneuvers for me.

1903 Wright Flyer Replica
at Mall of America
by Pete Gavin
V
olunteers from a broad spectrum of aviation groups joined
forces recently to present the best of aviation to an international audience. Under the sponsorship of the Minnesota Flight Expo, this
group hosted a public display of the Expo’s 1903 Wright Flyer replica 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 organizations participating in the event.
Shoppers of all ages enjoy the display
Whether aviation enthusiasts or not, the crowds
could not fail to be impressed by the quality
workmanship and faithful
reproduction of the 1903
Flyer. Those who contributed the long hours to
construct the replica, including Chapter 25 members 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 replica, leaving enough room for shoppers to see the Flyer from all directions 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.
Chapter 25’s John Sullivan with Ruth Hoglund
of Northwest Airlines Retirees Association
ON FINAL SEPTEMBER 2003
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 evening when the mall
crowds were thinning
out, yet a steady stream
of visitors kept the volunteers busy the entire
evening. I was most
impressed by the professional demeanor,
knowledge,
and
friendliness of the volunteers 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 volunteers at work.

IO470 Hot Start
Procedure for
Beechcraft
by Frank Hanish
O
ver 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 procedures. 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 perfectly clear running powerplant. However, recently one evening after a short flight the aircraft sat for an hour in 90 degree temperatures with a dewpoint of nearly 75 degrees
(which is tropical, and rather rare here in Minnesota) and virtually no wind.
First order of business, was thank goodness for a strong battery! 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 necessary, or even if not sure...) but it's what’s done after this procedure that may result in continually flooding the engine.
Safety Wire Tool
by Don Sektnan
Here
is a simple safety
wire tool that can be made
from a screw driver. Either 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, working 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.
“It is only with the heart
that one can see rightly;
what is essential
is invisible to the eye.”

Young Eagles at Airlake
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, everything 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 curriculum 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.
