118 MODEL AVIATION
World-record flight re-created by modelers in scale fashion
HAPPY NEW YEAR and welcome to
2006! For those of us who may have lost
some of the passion for modeling in 2005,
now is a good time to get back on track with
renewed enthusiasm. The new year offers us
all a fresh start, so take advantage of it and
get going!
I have often mentioned that a model
doesn’t have to be scale to be an RC Giant,
although the overwhelming majority of
submissions I receive are exactly that: flying miniatures. John
Sabini of Brentwood, New York, has a great RC Giant that is not
scale.
This beautiful Sig Rascal ARF 110 received its name because of
its 110-inch wingspan. It has 1,522 square inches of wing area and
a length of 75.75 inches. The model’s flying weight is 11-13
pounds.
John installed an O.S. 160 twin four-stroke glow engine in the
nose and added some nice detail work to his model such as a
turned-aluminum finish to simulate an engine cowling, rivet detail,
and antenna pods.
Although the Sig Rascal is not a scale model, it has the classic
lines of a Golden Age-era aircraft. John used a soft engine-mount
system available from Sig. When the engine is running the
cylinders vibrate slightly, as do those on the full-scale airplane.
Nice touch.
I had the opportunity to fly the Rascal and, like John, I am
pleased with its gentle handling characteristics. When he is not busy
building and flying models, John pilots an Airbus 320 for a living.
Too much of a good thing—airplanes in this case—isn’t bad!

Balsa USA’s newest kit is a 1/3-scale Fokker D.VII that was flown at
the Old Rhinebeck Aerodrome in September 2005.
Those prolific modelers at Balsa USA have done it again. The
company’s latest offering is a 1/3-scale Fokker D.VII. The model
spans 118 inches and should weigh roughly 40 pounds when
completed. The wing area is a massive 3,818 square inches, and a
50-80cc engine is needed to power this beast.
The kit will feature precut, custom bent-steel fittings; namebrand
hardware; a functional bungee-cord suspension; and sprung
tail skid. The wing features plug-in wing panels using aluminum
joiner tubes.
The Fokker D.VII will not have rigging wires, but not because
they were accidentally left out. The full-scale Fokker was one of the
few World War I aircraft that did not have landing and flying wires.
I photographed the prototype in a flyby at the Old Rhinebeck
Aerodrome during the modeling portion of the air show in
September 2005. The D.VII was an impressive sight.
Nice work, Balsa USA!
Leave it to modelers to re-create history in their unique way. Shawn
Kappner and Dick Rose of the Hamilton Area Wireless Kontrol
Society (HAWKS) of Hamilton, Ohio, submitted the following.
June 4, 1935, Fred and Algene Key set the flight-endurance
record of 653 hours, 34 minutes, in a Curtiss Robin J-1 Deluxe they
dubbed “Ole Miss.” They were resupplied with fuel, oil, food, and
water 452 times from another Robin through an overhead hatch in
the cabin during the flight. Traveling an estimated 52,320 miles—
twice the earth’s circumference—this record still stands.
A synopsis of the Key brothers’ feat can be found at
www.airminded.net; use the link to Golden Age Aircraft. TodayNational Air and Space Museum. Fred and
Algene had a true passion for aviation that
many modelers share today.
Although it was not one of the most
attractive airplanes, the full-scale Curtiss
Robin turned out to be one of the most
storied aircraft of the Golden Age of flight.
It was noted for the strength of its fuselage
and large area of its passenger cabin. It was
a reliable and rugged airplane that was
suitable for flight training and carrying
passengers and packages.
The airplane that held the previous
endurance record was also a Curtiss Robin,
but it had flown for 647 hours and 28
minutes. Another of its noted achievements
was a transatlantic flight from New York to
Ireland.
In 2004 HAWKS member Shawn
Kappner purchased a partially completed
World Models/Maloney Robin 99 from a
fellow club member. He searched the
Internet and found the history of the Key
brothers’ endurance record and conjured up
a dream about doing the same thing, but on a
scale basis.
Shawn reasoned that a commemorative
flight might be flown on a scale of one
minute for every hour flown by the Key
brothers. He shared the idea with fellow club
member Dick Rose, and the pair began to
study what would be required.
The previous owner “kit-bashed” the
Robin for the sake of scale detail, and it was
quite heavy. Considering the weight without
engine, the wing area, and the airfoil, Shawn
and Dick settled on a Zenoah G-62 engine
for power because of its proven reliability
and magneto ignition, which eliminated the
need for battery-powered ignition.
After some endurance testing it became
apparent that the model needed to carry a
minimum of 378 ounces, or 23.6 pounds, of
usable fuel. A complex system of two 5-
quart gas cans and one 50-ounce header tank
was adapted, with the large tanks under the
wing and the header tank in the nose.
To assist the Walbro carburetor pump, a
muffler pressure system was devised that
was similar to that commonly used on glowfuel
engines. With 1/4-scale servos, the
battery consumption required three 2700
mAh batteries. The aircraft became
extremely heavy—44 pounds with a wing
loading of 57 ounces per square inch—but
was flyable.
After several more test flights the
commemorative flight was attempted.
However, it failed after two hours because of
a fumbled transmitter swap. The aircraft
crashed and was destroyed.
Not to be denied, another used Robin 99
was purchased. It was well worn and had a
Zenoah G-38 engine. After numerous repairs
and partial re-covering, Shawn and Dick
found that this model was roughly 10 pounds
lighter than the first and theorized that the
venerable G-38 might be adequate.
Again, the pair performed numerous
calculations and tests, and they found that
this aircraft could meet the requirement with
considerably less fuel, standard servos, and
one less battery. The header tank was
eliminated, and the muffler pressure system
was retained. A three-hour test flight
confirmed their calculations.
Kirby’s Kustom Vinyl Graphics made the
Robin’s graphics to display the information
about this memorable aircraft, the feats of
the Key brothers, and this commemorative
flight.
September 10, 2005, at 8:05 a.m., Shawn
and Dick began the flight of the RC Robin
99 to commemorate the Keys’ historic flight
70 years earlier. It was a warm and humid
day, with variable winds at 2-8 mph. The
pilots flew 30-minute shifts to provide each
120 MODEL AVIATION
other with relief from the stiff-neck syndrome
and to refuel and “defuel” their bodies.
The aircraft was stable from the onset and
flew at half throttle or less for the entire
flight. During this long endeavor, two
transmitters were used and swapped when
battery voltage dropped below 9.6. A third
battery was rotated into the mix, which
allowed both transmitters to always have a
good charge while the third battery was being
recharged.
Each swap was made on a “one-twothree”
command, where the weaker
transmitter was shut off and the stronger
transmitter was turned on. Unlike the fumble
on the first attempted commemoration flight,
these well-rehearsed exchanges were
seamless!
At the end of the flight at 6:58 p.m.,
Shawn and Dick were surprisingly fresh and
felt they could have flown a few more hours.
After Shawn guided the aircraft to a smooth
landing, both pilots posed on the runway for
some photos to record the flight for posterity.
A witness sheet was maintained and signed
by several people, certifying that this flight
took place on the date and times claimed.

Congratulations on your achievement,

for a day. Let’s see who is going to come up

Make your New Year’s resolution to get

great hobby/sport.
Stay warm! I’ll be back next month
