STRAIGHT AND LEVEL
By Bob Lickteig
President
Antique/Classic Division
Oshkosh '84 once again earned the title of the world's
greatest aviation event. New records were set in all areas
of activities and with the weatherman cooperating, all
events and programs were completed as planned.
Those of us who have participated in this Convention
for many years could see, feel and hear the enthusiasm
generated by all members and guests. Everything was on
a high note from the Warbirds to the Ultralights.
The Antique/Classic area with a new porch on the Red
Barn was the talk of the Convention and attracted the
largest crowds ever seen in our area.
Chairman Jack Copeland, Co-Chairman Ray Olcott
and their volunteers did an outstanding job. I would like
to thank them all for their cooperation and maximum
effort. Without the support of all of these wonderful people,
your Antique/Classic Division could not undertake an
event of this magnitude.
Oshkosh '84's success can be shown by a few p r l i m i ~
nary figures that I know will interest you. The number of
registered antique and classic aircraft was up 103 over
last year - 128 antiques and 607 classics. Thanks to Art
Morgan and his volunteers, there were no parking prob-
lems and parking by aircraft type did work.
The Antique/Classic flyout had 40 aircraft and approx-
imately 100 people. What a day with fun for all, thanks
to Bob Lumley.
The reunion of past grand champion and reserve grand
champion antique and classic aircraft arranged by Al
Kelch was the largest such activity on the field. Seven
aircraft were displayed in this honored circle, and many
fine comments were made by members.
The reactivation of the Antique/Classic picnic on
Wednesday night resulted in a turnout greater than ex-
pected, with 420 people enjoying fine food and a great
social hour, thanks to Bob Kelly.
The first photo contest of the Antique Classic Division
attracted 26 entries. Jack McCarthy not only organized
the contest but gave us complete photo coverage of all our
activities.
Our headquarters staff at the Red Barn was busy
throughout the convention, with Kate Morgan, Ruth Coul-
son and Jo Olcott handling merchandising sales over twice
the amount of any previous year.
The Antique/Classic Parade of Flight - the annual
highlight of the Wednesday air show - had 96 airplanes
participating. Phil Coulson did his usual excellent job of
organizing.
The Type Club headquarters tent was full with 10
clubs displaying and conducting their business. Chairman
Butch Joyce is now planning on a larger tent for next year.
The Antique/Classic forums handled by Ron Fritz had
the largest attendance on record for these interesting and
informative sessions.
Roy Redman had a merchandising and chapter stand
in a highly visible place, and it was busy all week. We
signed up 121 new Antique/Classic members and talked
with approximately 10 members who are interested in es-
tablishing new local chapters in their area.
Dan Neuman arranged for and conducted 18 inter-
views in front of our Red Barn headquarters. This is twice
as many as we have ever had before, and member and
guest comments were encouraging.
Congratulations to our Antique/Classic judges! They
had a very difficult task this year with the great numbers
of qualified aircraft to judge.
You will see and read more about these activities in
future issues of THE VINTAGE AIRPLANE.
I cannot close without thanking everyone again for
their kind comments regarding the Antique/Classic Divi-
sion's significant part in making Oshkosh '84 the best
EAA Convention yet.
We are already planning for Oshkosh '85, and I can
assure you everything we enjoyed this year will be larger
and more exciting next year.
From the new guy on the block, thanks again to
everyone . •

AT LAST-
A PORCH ON THE RED BARN
The long-awaited porch on the Antique/Classic Head-
quarters, also known as the Red Barn at Oshkosh will
have been completed by the time this issue reaches the
readers. All the design and construction work was done
by volunteers, mostly members of Antique/Classic Chap-
ter 11 from the Milwaukee, Wisconsin area.
The project was headed up by Al Kelch of Mequon,
Wisconsin who contributed many hours and dollars, and
put many miles on his van driving to and from the work-
site and picking up tools and materials for the job. Al
shopped around and negotiated some real bargains at
local Oshkosh lumber and supply outlets.
Initially the covered porch was to have been only on
the north side of the Red Barn, but when construction was
begun, it became obvious that there were many advan-
tages to extending it to the east side. Not only was the
area of the porch doubled, but it now provides protection
from the elements for the main entry to the building.
Most assuredly, the porch is one of the choice spots on
the Convention grounds where folks can relax and visit.
A big thank you and a well-deserved pat on the back is
due each volunteer who worked so hard to complete this
fine addition to the Antique/Classic Red Barn.

Aero Digest is the premier aviation journal for those
students of aircraft in the Golden Age of Aviation in the
United States. Foremost in its field, this journal covered
all aspects of civil and military aviation.
Its strongest suit was in its descriptions of individual
aircraft. Also covered were technological advancements,
record flights, history, personality profiles, air races, and
foreign activities. It was profusely illustrated with photos
and three-view drawings.
The April, 1928 issue provided articles and descrip-
tions on 18 different aircraft. Among the aircraft covered
in this issue were the Taylor "Chummy", Bellanca 6-pas-
senger monoplane, Alexander Eaglerock, Avro "Avian",
and the Fokker F-I0 Super Trimotor. There was also a
three-page article on the Cierva Autogiro.
The journal not only kept track of developments of
light aircraft such as the Taylor "Chummy", it helped to
foster their development through the Aero Digest Trophy.
This trophy was awarded to the winner of the speed and
efficiency race for planes with under 80 cubic inch dis-
placement at the 1925 New York Air Races.
Not only were the articles and notices on aircraft infor-
mative, but so were the advertisements; many of which
were full page. Aero Digest prided itself on the amount of
aeronautic advertising. It stated that it provided a
"greater variety of advertising than any other aeronauti-
cal publication." The May, 1929 issue was a good example
with over 340 advertisers.
A large proportion of its advertising was by aircraft
manufacturers. A comparison of a 1929 issue of Aero Di-
gest with one of Aviation shows that 38% of Aero's adver-
tising was for aircraft while Aviation had 25%. Thus Aero
Digest is a very good source for aircraft manufacturer's
information.
Though not noted for its cover art work, as most of its
covers were duo-tone, Aero Digest did have some full color
ad inserts. The most colorful of these were from the Berryl
Brothers Paint Company. These full page, full color ads
featured fanciful finishes for well-known aircraft of the
day to give them the appearance of birds. Aircraft such as
the Eaglerock and the Buhl Airsedan were finished to
represent birds such as Bald Eagles and Macaws. A dozen
of these ads appeared on a monthly basis starting with
March, 1929.
Another valuable feature of Aero Digest is its roster of
important authors. Names appearing in the table of con-
tents included Giuseppe Bellanca, Charles Lindbergh,
Clarence Chamberlin, Al Williams, General William
Mitchell and Rear Admiral Moffett. Articles by these au-
thors not only talked about technology and flying but
about the impact and future of aviation.
An important source of aircraft information was the
journal's "Annual Digest of American Aircraft." This an-
nual series, which began in April, 1935, was preceded by
an irregular feature - "Descriptions of approved type
airplanes and engines," which first appeared in April,
1931. The descriptions were a third of a page each and
provided two photos and a three-view drawing plus specifi-
cations for each aircraft. The first appearance in 1931
covered 90 aircraft from the Aeronca to the Zenith Z-6-B.
The annual directory appeared as the March issue from
1935 to 1956.
The size of the issues of Aero Digest reflected the
growth of the aviation industry and the interest it generc
ated. In the early 20s, the issues consisted of 50 to 80
pages. After Lindbergh's flight , this jumped to 150-180
pages. The size continued to grow from there with the
peak coming in September, 1929, with an issue of 366
pages. The last issue of December, 1956 had only 48 pages.
Aero Digest was published by the Aeronautical Digest
Publishing Corporation of New York. Its second president,
Frank Tichenor, for several years provided an editorial
column called "Air - Hot and Otherwise."

Timm "Collegiate" NC279V comes in for a three pOint landing with Floyd Newton at the controls. Slow landing speed of 35 mph
makes the job easier.
A POST MORTIMM

Newbury Park, CA 91320
Purists in the field of prescriptive grammar wince
painfully when they hear the adjective "unique" used in
the comparative or superlative degrees. How, they lament,
can anything be "more unique" or "most unique" when,
by definition, the distinction of being unique guarantees
that there is only one of its kind in all of creation? With
cautious attention to the foregoing metes and bounds, we
can safely say that the aircraft described in the following
is unique - the only one of its kind still extant! Timm
Collegiate, "City of Los Angeles", NC279V remains the
sole survivor of the scant half dozen such planes turned
out by the struggling Timm Aircraft Company before it
succumbed, in April 1931, to the economic ravages of the
Great Depression.
Otto Timm's venture into the risky business of aircraft
design and production, undoubtedly, can trace its begin-
nings to Charles Lindbergh's daring conquest of the Atlan-
tic in 1927. Ambitious designers, now encouraged by the
newly proven possibilities of aviation, were eager to apply
their skills to this exciting field which had been so vigor-
ously stimulated by Lindbergh's celebrated flight.
Likewise, the economic climate had become much more
6 SEPTEMBER 1984
hospitable towards an industry that had suddenly dem-
onstrated its ability to produce something more worth-
while than just expensive play toys.
It was into this new but promising arena of combat
that Otto Timm elected to cast down his gauntlet. A fac-
tory site, adjacent to the Glendale, California Airport was
acquired, and, in September of 1928, Timm Aircraft Com-
pany became a reality midst rampant but justifiable op-
timism.
At this point, who could guess that, even then, ominous
clouds of economic catastrophe were gathering on the hori-
zon preparing to unleash their torrential deluge of disaster
in little more than a year? Timm Aircraft survived until
April of 1931, but in those difficult 31 months only six
Collegiates would reach completion.
Timm's creation was truly innovative for its day.
Whereas previous designers of training planes had persist-
ently shackled themselves to the biplane concept, Timm's
parasol craft boasted less drag and far better visibility for
having departed the stereotypical biplane theme.
A number of powerplants were variously employed in
the Collegiate, but the one that powers "City of Los
Angeles" is certainly the most interesting (but not most
unique!). This particular aircraft was the fifth plane pro-
duced by Timm and was purchased by J. Warren
MacClatchie to serve as a test bed for a new engine of his
own design.
Let's apply a little logic here. If you have an aircraft

on the right.
that boldly breaks with accepted traditions (the parasol
Timm), why not mate it with an engine that likewise
flaunts convention (the L-head MacClatchie)? That's the
ultimate in iconoclasm!
Now, whoever heard of an L-head aircraft engine? This
writer certainly never did except for those less than artis-
tic attempts from the late twenties through the mid-thir-
ties when several hopefuls tried desperately to give wings
to various motorcycle and automobile engines. Nonethe-
less, the seven cylinder, 150 horsepower MacClatchie
Panther appeared on the scene at this time and dared to
introduce an L-head valve concept to the field of aviation.
True, practically all automobile engines of that period
featured this same flat head principle, but even they con-
verted to overhead valves in the late "forties" and early
"fifties" when the insatiable demand for additional horse-
power necessitated the change.
The MacClatchie valving, like all other L-heads, ex-
tracted a small penalty in volumetric efficiency and resul-
tant horsepower per cubic inch, still, on the plus side, it
provided smaller overall diameter (and drag) plus far less
costly construction and maintenance. It is estimated that
it required 400 fewer parts than similar overhead contem- •
poraries. And how many seven cylinder radials of 612
cubic inches displacement can boast a trim diameter of
only 36 inches?
Lest there be any doubt as to the reliability of this
simple but sturdy engine, let it be noted here that, on
November 15, 1930, this MacClatchie powered Timm, fly-
ing out of Rosamond Dry Lake, California, established a
new world's record for non-maintenance fl ights. This
grueling test permitted a landing every four hours to
change pilots and take on fuel and oil , however, at no time
could the engine be shut down nor even the simplest
repairs or adjustments be made.
This tortuous grind went on for 378 hours and 48
minutes, ultimately being terminated because of two
"fouled" spark plugs. The number of landings totaled 97
and average ground time was 10.2 minutes. For the statis-
tically minded, 18.5 gallons of oil and 2,717 gallons of

gasoline (7.1 gal.lhr.) were consumed.
At the conclusion of this endurance run, the aircraft,
equipped with a new "Panther" engine, was awarded to
Leo Root, one of the three pilots who participated in the
record flight. At this late date, a rumor that refuses to die
insists that Leo was the last pilot to fly in the endurance
test, and when it was discovered that he and the airplane
had inseparably grown together, there was little choice
but to formalize the union by awarding him the airplane.
The travels and travails of NC279V, from this point
on, would rival those of the legendary Aeneas and Odys-
seus. Summarily, it goes something like this: From Leo
Hart, she went to an unnamed brother-in-law who in turn
transferred ownership to a R. L. McCreery. McCreery
parted company with our heroine in 1936 or 1937, and her
history is totally obscured from that time until she reap-
peared in Prescott, Arizona late 1941. We can only guess
as to the doughty lady's whereabouts in this interim
period, but her general appearance, when she surfaced in
Prescott, strongly suggests that she fared not too well .
At this point, the Timm, in a partially disassembled
state, was acquired by the Prescott High School to serve
as a classroom training aid. Sadly enough, this acquisition
was accomplished for the settlement of a $150 lien plus a
paltry $100 to the owner! How can a virtuous lady fall so
low?
The next scene in our little drama is dated 1947 and
shows "279V" being purchased by agriculture pilot Mack
Sheers of Buckeye, Arizona. Mack had gathered together
quantities of surplus WW II aircraft and engines in what
some have described as an aeronautical junk yard, and it
was into this ignominious scene of refuse that our proud
little parasol bird was committed for what easily could
have been her final home and ultimate demise were it not
for Keith Skeers and Floyd Newton of Phoenix.
The elements continued their relentless assault in
these unfriendly surroundings, and, indeed, if she was not
lifeless at this juncture, then certainly moribund. Photo-
graphs offer ample proof that only an incurable optimist
would dare lay his hands to a restoration miracle at this
stage. Most will agree that an Arizona junk yard is hardly
a fit spawning ground for the rebirth of a classic creation,
yet it was against such an ignoble background that Timm
Collegiate NC279V was rescued and given a second chance
at life.
SHEERS TO SKEERS: In 1975, Keith Skeers of
Phoenix purchased the now sadly deteriorated craft from
Mack Sheers and resurrection began. The scene of the
many surgical and therapeutic ministrations was the Lyle

Alexander Aircraft Service located at Glendale Airport in
Peoria, Arizona. Those baffiing Goddesses of Fate must
have had a hand in this. Our Timm first saw the light of
day at Glendale Airport in California - her rebirth oc-
curred at Glendale Airport in Arizona!
But whatever the mysterious and unseen forces at play
here, the visible fact was that, in the coming months and
years, many willing hands would take part in this chal-
lenging and exciting project. Keith and Jack Sheble re-
built the fuselage, which required extensive sandblasting
and welding plus the addition of replacement pulleys and
cables. These two also rebuilt the MacClatchie into a
like-new engine.
Only eight of these powerplants had been built, and
any spare parts that had previously existed were lost
forever in a warehouse fire in 1943. Cylinders had to be
rebored and resleeved, while parts that had to be manufac-
tured included pistons, bearing and valves. Fortunately,
truck engine valves were found which very closely approx-
imated those of the MacClatchie.
Meanwhile, experienced aircraft restorer and master
craftsman, Floyd Newton (EAA 187544, AlC 7777), under-
took the exacting job of creating a new wing (the original
was beyond repair). This task alone consumed 18 months
of Floyd's time and was, for the most part, accomplished
in his own garage.

Old timers will recognize the identification of the air-
foil - a Fage and Collins #4. This more than ample wing
(8.27 lbs/ft 2) boasts a seven foot chord with one rib per
foot and nose ribs evenly spaced between main ribs.
Finally, after four years and two months of arduous
but unflagging effort, all things came together, including
an FAA inspection, and the Collegiate was ready to re-
claim her rightful place in the sky. A few shots of primer
and the durable MacClatchie roared to life after not hav-
ing spoken for 38 years. The memorable day had arrived.
Floyd and Keith gave their mount a few taxi tests in order
to familiarize themselves with the Johnson Bar and dif-
ferential rudder braking system as well as the full swivel
tail wheel.
The old girl was proudly resplendent in her glossy new
finish, but we won't say she looked like new - no, she
was better than that. Her benefactors had seen to it. Still,
that first ride she gave them in 1979 was "payment in
full" for the 50 months of unstinting dedication they had
given her.

The aircraft has logged a total of 65 hours since that
first flight in 1979, and the reliable MacClatchie unfail-
ingly starts on the first pull of the prop. Floyd, who has
been at the controls all of those 65 hours, reports that the
Timm is a pleasure to fly - not a great deal faster than
the freeway traffic, but "smooth and solid". And the L-
head MacClatchie, in a sense having a built-in muffier,
makes for a very quiet operation.
Unfortunately, rumors have a way of spreading, and
it is a well -known fact that wagging tongues only
maximize - never minimize. Keith and Floyd would like

robbers! The little lady most assuredly showed some signs
of life when they retrieved her from the aeronautical junk
yard - they merely nursed her back to health!
And if you should happen to see the old girl primly
posed on the ramp at some fly-in or parked under her
shelter at Glendale Airport, it may occur to you that you
detect a trace of haughtiness about her. If so, I hope that
you will be willing to overlook it, because after all, she is
unique.

A POST MORTIMM
The age of flight is fleeting brief,
But wrought with noble deeds.
The harvest that we reap today
Was brought from humble seeds.
No single sculptor shaped its form
Nor author etched its course,
The architects who raised this art
Were drawn from every source.
Their visions and their labors
Did much to chart the way
For those who came along this path
In the light of another day.
But sad to say not much remains
Of the vintage craft of yore.
Their numbers lessen day by day
And soon there'll be no more.
Phantom ships with ghostly fOl 'ms
They know times ceaseless toll.
Their crumbling wasted shapes foretell
The nearness of their goal.
One such hulk had gone to rest
In the Arizona land
Where sun and wind complete the task
Of the restless, drifting sand.
Though few would know or care a lot
Twas a Timm of "twenty eight"
MacClatchie was the power plant
And oblivion was its fate.
But Floyd and Keith, this stubborn pair,
They just don't comprehend
That some things are beyond the skill
Of human hands to mend.
They worked by day, they worked by night.
They really didn't know
That lifeless bodies such as this
Are better left below.
Yet on they toiled, this doughty two
Only God in heaven knows
But somehow from this shapeless mass
A handsome craft arose.
T' would not be fair to say it was
The same as Timms when new
'Cause it far exceeded those produced
By the original factory crew.
Both near and far it wins first prize
At antique airplane shows.
It's guaranteed to be the best
No matter where it goes.
Some now say, "just leave it home,
We'll mail the prize to you,
But give some other slob a chance
To see what he can do."
But strange to say, this Keith and Floyd
They still don't comprehend
That some things are beyond the skill
Of human hands to mend.

The last week of June is usually a very special time
for Waco owners and admirers. The most dedicated will
annually either fly, drive, walk or crawl to attend the
greatest gathering of meticulously restored Waco
airplanes ever to assemble on one airport. Wacos from
coast to coast and from Canada usually make up this
awesome display each year at Hamilton, Ohio.
Beautiful Wacos flew in from such distant points as
Denver, Colorado; Fort Worth, Texas; New Orleans,
Louisiana; Ocala, Florida; Trenton, New Jersey; Bethel,
Maine; and Rapid City, South Dakota. The four-day reun-
ion of Waco pilots started with an impromptu picnic at the
Hamilton Airport on Thursday evening, June 28, 1984.
Friday's activities included additional arrivals of beau-
tiful Wacos. Throughout the day another delicious bar-
becue was prepared by Waco club member George Vaughn
and members of his family at the Hamilton Airport. A

restoration and maintenance forum was conducted Friday
afternoon while sitting on the grass in the shade of one of
Hogan Air's DC-3s. This provided excellent sharing of
information leading to sources for critical replacement
parts for Waco airplanes.
That evening, many outstanding slides of Wacos from
previous Waco reunions, dating back to 1974, where
shown in the refreshment hangar at the airport.
. By Saturday, there was a mass of Wacos and Waco
admirers. That evening, the annual Waco Reunion Ban-
quet was held at the very comfortable facilities of VFW
Post 1069 and was attended by approximately 230 persons.
Following an excellent buffet, an outstanding program
was provided with such notable Waco personalities as
Charlie Moffitt, Waco parts and service manager,
Montgomery "Monty" Chumbley, Waco sales promotion
manager for Central and South America, and Len Povey,
aerialist supreme and a member of the American Air Aces
Show prior to being appointed by Generalissimo Batista
to head up and reorganize the Cuban Air Force. These

persons provided a very interesting program as they re-
lated some of the many interesting past experiences of
their lives during a very colorful period in aviation.
A special commemorative patch was awarded all pilots
who flew a Waco to this 25th Annual Reunion. Fifty-year
pins were awarded to Harmon Moss and Dick Jackson
whose Wacos celebrated their fiftieth birthday this year.
Dick Jackson's S3HD, the only Model "D" to ever be sold
within the U. S., is also the only one known to exist today.
This outstanding high-performance Waco is restored and
maintained in immaculate condition, including its origi-
nal colors.
All activities on and off the airport were again
adequately coordinated by Waco Club member Mike Heins
and his very unique commuter bus.
Sunday was "fly-out" day as the many colorful Wacos
taxied out and headed for their distant homes. With the
25th Annual Waco Reunion almost a memory, we find
ourselves eagerly anticipating next year's reunion of old
and new Waco friends . •

These outstanding Wacos are owned by Dick Jackson of
Rochester, New Hampshire and Mike and Pete Heins of Dayton,
Ohio respectively.

ANTIQUE/CLASSIC
MAINTENANCE TIP
Wood Propellers: Installation, Operation & Maintenance
Integral Flange Crankshafts
Your Sensenich wood propeller was manufactured
from aircraft quality selected lumber. The laminations
are bonded with high-strength water-proof resorcinal
glue, and were assembled under closely controlled factory
conditions. Propeller balance was strictly maintained dur-
ing manufacture and verified before shipment from the
factory. Assembly of Type Certificated propeller/engine/
aircraft must be accomplished by personnel holding the
appropriate FAA license.
Installation of the propeller will require a front face
plate of adequate stiffness (approximately the same size
as the propeller hub), a flange adapter (in some cases), and
a set of attaching bolts of the proper length.
It can be shown that an engine must deliver its driving
torque to a good propeller through static friction. That is,
the force which resists movement of the propeller hub on
the engine fl ange is due to compression of the wood surface
against the flange. Therefore, it is important to avoid
crushing the wood. Although the drive bushings incorpo-
rated in most flanges provide a back-up system, a load will
be imposed on them only if there is a movement of the
propeller on the flange. The bushings can carry engine
driving-torque loads for only a short period of time.
Forest Products Laboratoryl data for Yellow Birch
wood shows that the optimum compression pre-load of a
wood propeller hub is approximately 0.006 inch per inch
of hub thickness (i.e. : a propeller hub which is 1 inch thick
before installation should be compressed 0.006 inch to a
thickness of 0.994 inch by drawing up the propeller attach-
ing bolts). Knowing the hub thickness and the number of
threads in each inch of attaching bolt thread, it is possible
to calculate the proper additional rotation of each attach-
ing bolt after the front face place, propeller, and flange
(or adapter) are snug. For example, a propeller hub which
is 4.50 inches thick should be compressed 0.006 * 4.50
equals 0.027 inches. If 1/2 inch dia. bolts are used (112-
20UNF threads) , they should be turned 0.027 * 20 =
0.54, or just over 1/2 revolution after the front face plate,
propeller, and flange are snugged. See Table No. 1 for
examp.les of common installations.
Generally recommended wrench torque to achieve
proper hub compression against standard flanges are in
Table No. 2. These torque recommendations do not con-
sider variations of thread condition, and assume that the
threads of the bolts and in the drive bushings are clean
and dry.
INSTALLATION PROCEDURE
After study of the preceding discussion of wood propel-
ler installation requirements and of your propeller assem-
bly, the following installation procedure should be fol-
lowed:
1. Be certain that the magneto switch is "oft" and that
both magnetos are grounded.
2. Install the flange adapter, if required. Adaptor re-
tention bolt wrench torque recommendations can be found
in Table No.3. Install safety wire in heads of adapter
retention bolts in pairs, following the safety wire groove
provided in the adapter.
3. Locate the propeller on the engine flange, or adapter,
in most convenient position for handcranking.
4. Remove a spark plug from each cylinder. Chock the
aircraft's wheels to prevent movement.
5. Install the propeller attaching bolts "fingertight", so
that the face plate, propeller, and flange are snug (but the
wood has not been compressed). Check track of the blade
tips by rotating the tips past some fixed object on the floor.
16 SEPTEMBER 1984
The tips must track within 1116 inch of each other when
the installation is completed. Track should be corrected at
this time by snugging up the bolts nearest the blade which
is forward. This will result in a common starting point for
all of t he attaching bolts.
6. Tighten the attaching bolts in small increments,
moving diagonally across the bolt circle. It is good practice
to check track frequently while tightening the bolts. Take
care to tighten bolts on opposite sides of the blade center
line evenly so that blade-to-blade conformity of angles is
maintained.
7. Since a small part of the wood compression is plastic
(permanent), it is good practice to loosen the bolts, and to
allow the wood to relax for an hour. Retighten following
the same procedure.
8. Install safety wire. It is good practice to wire the
attaching bolts in pairs (not a continuous wire), twisting
the wire between bolt heads. •

The clean lines of this airplane in
this front view are unusual for 1927
when the airplane was built. The
photo is from the Wally Norman col-
lection recently donated to the EAA
Aviation Museum. This was another
attempt by a well-known designer to
meet the demand for a light transport,
the result of the boom in aviation
triggered by Lindbergh's successful
transatlantic flight. Answers will be
published in the December, 1984
issue ofTHE VINTAGE AIRPLANE.
The Mystery Plane for the June,
1984 issue of THE VINTAGE
AIRPLANE was no mystery to H.
Glenn Buffington of San Diego,
California, who writes, "The June
Mystery Plane is the Commercial
'Sunbeam' used by Bobbie Trout and
Elinor Smith in setting the first in-air
refueling record for women, 45 hours
5 minutes on November 27-29, 1929.
It was built by the Commercial Air-
craft Corp. , Van Nuys, California and
was powered with a Wright J-6 300
hp engine. The girls flew it without
the wheel fairings during the record
flight." A first-hand account of this
record flight is given in Elinor
Smith's book Aviatrix. Doug Rounds
of Zebulon, Georgia and Dr. H. M.
Richey of Waco, Texas also correctly
identified the airplane. Note the
streamlined tube extending from the
upper wing to the cabin roof, evi-
dently the arrangement to accept the
fuel into the tanks.
But a deeper mystery arises. The
first mention of the Commercial "Sun-
beam" appears in WESTERN FLY-
1NG for April 1929, which includes
the statement that no orders would
be accepted until the ATC had been
granted. Then in AVIATION for Oc-
tober 19, 1929, it is reported that the
plane is in production and orders for
seven had been obtained. And yet
there is no record of an ATC being
issued nor is it listed under Group 2
approvals. In AVIATION for Feb-
ruary 1, 1930 the airplane is de-
scribed and a photo of a "Sunbeam"
with license X-137E is shown. The
one shown in the Mystery column is
licensed X-564M.
One member identified the airplane
as a Zenith Z-6 licensed under Group
2, numbers 2-212, 2-269 and 2-315.
Comparison with the photos shown in
Juptner's U.S. Civil Aircraft, Volume
9 shows a distinct resemblance to the
"Sunbeam" but the power is listed as
being a Pratt & Whitney Wasp of 420
hp and seating for 6 passengers and a
pilot. The "Sunbeam" used the Wright
engine and seating for 4 passengers
and 2 pilots. Could the Zenith Z-6 be
a development of the "Sunbeam"?
Would that account for the missing
registration number for the "Sun-
beam" or am I missing some impor-
tant references? Who has the answer? •

One phenomenon of the scientific world was lost to
history because the members of the news media who had
witnessed it had either retired or died off before it was
understood or explained. I am referring to the terrific roar
of the old-time aeroplane power dive.
As every fireworks program has its grand finale thrill-

20 SEPTEMBER 1984
shows around 1930 thrilled the crowds with the grand
finales. In these, a squadron of prop planes, playing follow
the leader, would power dive down and flatten out in front
of the stands one after another. As each came down with
motors racing, additional distinct sharp explosive sounds
at the rate of about 100 a second would occur. They were
probably not quite as loud as those of an aerial bomb, but
they were plenty loud.
The crowds were thrilled by this demonstration and
most of them probably thought the extra roar came from
the motors. The pilot knew what he was producing, but
could not have explained what resulted. The early cattle
drover knew how to produce the explosive bank of his
bullwhip, but could not have explained what actually
caused it. For a while it was thought that the sudden
turning of the "cracker" caused a vacuum in the air which
gave a loud bang when it came together again. Then came
the modern sonic boom.
For a while there was much fumbling in explaining its
cause. A British aeronautical publication stated that two
booms occurred each time, one when the plane exceeded
the speed of sound and another when it slowed down. I
had wondered for years what caused the terrific roar of
the early power dives. They had stopped in the '30s be-
cause adjustable propellers had slowed down the RPM of
the motors. Then in 1966 the explanation came to me. I
was showing a film to my students, "Approaching the
Speed of Sound," put out by the Shell Oil Co. The film
showed what caused the sonic boom graphically and with
sound effects. Any object, large or small, builds up a shock
wave in front of it when it exceeds the speed of sound. It
is like the wake of a boat. The volume of sound it creates
when it reaches us depends upon the size of the object. The
small cracker of the bullwhip produces a loud firecracker-
like sound. The sonic boom of a jet plane is like that of a
cannon.
Now I had it - the tips of the propellors of those early
planes were creating good-sized booms when they ex-
ceeded the speed of sound during the power dive. Many
probably thought that the exhausts of the motors were
just that much louder and did not notice the distinctive
sharpness of the explosive sounds. It also explained why
a silencer is ineffective on a high-velocity rifle - the
bullet has its own explosive sound. (Could that be what
the spectators at the Kennedy assassination heard, think-
ing it was another gun over by the railway overpass?)
Having solved a problem and getting it before the
people who wondered about it for many years (as I had) is
another thing. I sent my calculations to the head of the
physics department of my alma mater for verification. The
reply - "Your explanation of change in character and
intensity of sound of a power dive is reasonable." There
was no attempt to pass this information on to those who
were so thrilled years ago. Sent to a popular scientific
magazine, the reply was "Irrelevant".
I sent it to the appropriate department of another
university. They had never heard it explained before.
They suggested that I send it to "Astronautics and
Aeronautics", a specialized publication. The answer was,
"According to our experts, propeller airplanes, like jets,
make most of their noise in terms of power drawn from
the engine - that is, the noise originates with the engine
itself." (The sonic boom also? Nuts!) This was the last
straw.
It finally dawned on me that none of these people were
old enough to have witnessed an old-time power dive. They
could not imagine what we had heard and wondered about
for so long, and those few who yet remain, regretably,
have never had it explained to them.

THE AVIATOR
As noted in the April and May issues of THE VIN-
TAGE AIRPLANE, THE AVIATOR WILL COME TO
TOWN .. . but unfortuntely, MGM has delayed the release
of its movie THE AVIATOR until this autumn. As a result,
EAA's participation in the release of the movie has been
reduced considerably from the plans we announced previ-
ously. Because of the delayed release date it would be
necessary for the EAA Headquarters stafTto initiate prep-
arations for the premier at the same time that they are
coordinating and organizing our own 32nd Annual EAA
International Fly-In Convention and Sport Aviation
Exhibition. EAA Headquarters has, for that reason, with-
drawn from participation in the mall exhibits and preview
showings of the movie. During this critical time period it
would be unwise to add a second major project to an al-
ready busy schedule. We have made this decision in order
to maintain the high standards EAA has become known
for in all of its activities.
EAA's decision to withdraw from participation in this
project should not be construed as a reflection upon the
movie or its producers. We are looking forward to seeing
it when released. Any EAA Chapter that is interested in
participating in the opening of THE AVIATOR at local
malls is encouraged to do so. •
