Cal
Branton invited our guest
speaker Charles Horihan, a
Vietnam-era pilot. Charlie
described training in a T38 Talon,
the highest performance military
aircraft at the time, capable of
climbing to 30,000 ft in 3 mi nutes
(average vertical speed 120 mph),
ceiling of 53,000 ft, and a roll
rate of 300 degrees/sec. Slow rolls
could be done with only rudder. In
one emergency pull-up he reached 9.3
Gs without losing consciousness due
to his G-suit. But the a/c was
rated for only 7.3 Gs. Some Dzus
fasteners were popped. Then he
“went off to fly C-130 Herky Birds”
because he “wanted to see the
world.”
He flew
Berlin airlift missions when there
“was a lot of stuff fresh from WW2.”
He helped put out oil well fires in
Iraq caused by Egyptian terrorists,
carrying pipe and
supplies and meeting the famous Red
Adair. Landing gear doors were
removed, and the wheels were
partially deflated in order to land
on sand. The movie Hell Fighters
with John Wayne is based on this
incident.
At the
age of 25 he went off to Vietnam,
Laos and Thailand to fly “airlift
stuff,” being told that the war
would be over in 6 months. He flew
“beans, bullets and bodies,” mostly
supporting the Army. Then he dropped
night flares over the Ho Chi Minh
Trail, illuminating trucks to be
attacked by Sky Raiders, F100s and
F4s (the F4’s were too fast to be
useful)—“a pretty Rube Goldberg
operation.” Over 200 million tons
of bombs were dropped on the trail,
more than all of WW2.
His
last assignment was flying Cessna
Bird Dogs as a Forward Air
Controller (FAC). They were
equipped with rockets which were
occasionally used. He radioed
targets to artillery units. A
“rewarding” accomplishment was
rescuing a group of surrounded
ground troops.

His
last day in Vietnam was the first
day of the Tet offensive in which
his Bird Dog was damaged, and he
escaped under mortar fire.
After
the war he did photo mapping in the
US and South America and flew for
NWA. When he retired at age 60 in
2001 he had flown over 26,000 hours
of which 1000 hours were in combat,
all accident-free. “I didn’t even
blow a tire.”
Returning to Vietnam as a tourist,
he found the people to be “very
gracious,” and “they treated us very
well.” |

John
Baligrodzki presented his Yellow
P-47. 8 flights so far. “Flies
nice.” Construction with the help of
Kirk Hall. John substituted a G62
for the standard G45. No balance
weight was required. He applied
13,000 vinyl rivets from
Fritz Designs
They
were applied after primer and before
Krylon Metal Silver. After much
experimentation, he found the |
best
results to be buffing each panel in
a different direction with 000 steel
wool. This surface is easy to
repair. “Repairs blend right in.”
He tried to repair a broken wingtip
with expanding foam but he used too
much and it “popped right off.”

Cal
Branton covered the wall with the
plans of a 50%
Scale Fokker Triplane, an
enlarged version of a quarter-scale
Glenn Torrence model. “Very scale.”
Cal previously owned a smaller Fokker
Triplane that was “the worst airplane I
have ever flown” so he “decided to build
another.” The structure contains 80
feet of dowels, mostly stringers. The
plane will be co-built with Kirk Hall.

Contrarian
David Andersen announced his
“one-man campaign to abolish the
pushrod.” He complained that pushrods
are not scale and they are a major
source of play that gets worse with time
if clevises are included. So he offered
three alternatives, and described their
advantages and disadvantages. They are:
-
The
Spangenberg aileron linkage that
uses two brass tubes and a ball
link.
-
A
rudder servo mounted below the
rudder, its arm having a slot that
accepts a round-head wood screw in
the rudder.
-
A “wing
servo” mounted in the elevator. Its
metal servo arm has a slot that
engages a metal tab in the stab.
The arm doesn’t move. Instead, the
servo moves with the elevator and
acts as another hinge.
He
demonstrated with the tail of Roy
Maynard’s Ki 45 currently under
construction.

Andersen LA-7 Plans Enlarged! |
Danny
Lanz enlarged
David Andersen LA-7 Plans
from a 96" wingspan to 120" and
he modified the design to include a
removable stab. Despite its
massive size, plane will
transport in a full size SUV with the
center section of the wing attached,
sitting on i ts
wheels. This makes for really
quick field setup for a massive Warbird.
The project weights about 85 lbs.
Painted with Model Masters paint and
tastefully weathered to eliminate the "ARF"
look.
A ton of
thought and about 2000 build hours have
gone into this project so far and still
needs the radio install, balance and
test flights.
The ¼
scale LA-7 uses; a Herbrandson 289cc 2
Stroke twin with a 36x16 3-bladed prop,
Hitec and JR digitals servos throughout
and heavy duty hardware, a Smartfly
redundant power system with Li-Ion
batteries, Sierra custom retracts, a
one-off canopy and cowl, rivets, panel
lines and scale piano hinges were used,
it has retractable tailwheel with doors,
a 3 piece wing, removable stab and a
Sierra custom 7 ¼” spinner.
