10 MODEL AVIATION
VTOL H-Wing
Ran D. St. Clair (1048 Jones Ct., Redwood City CA 94063; Email:
[email protected]) designed and built his VTOL H-wing,
which is capable of vertical and horizontal takeoff and landing. It
spans 24 inches and weighs 5 pounds, 11 ounces, less the removable
“swing gear.”
The model is made from 4mm Coroplast and uses an O.S. .61 FX
engine with a 14 x 4 propeller. The onboard radio gear includes an
FMA Direct FS8 receiver with integrated Co-Pilot, three rate gyros,
an in-line mixer, a custom control switch (to bypass the gyros), and
a prototype FMA Direct flight recorder.
According to Ran, forward flight is “normal,” with a talent for
high-alpha Harrier maneuvers. The Co-Pilot and gyros make the
model fully stable in “hover mode,” allowing vertical takeoff and
landing by a nonexpert pilot.
Semiscale Robin
Bill Hastings (269 N. 5th St., Creswell OR 97426; E-mail:
[email protected]) built his 99-inch-wingspan Curtiss Robin
from an Old World Models kit.
It is powered by a SuperTigre 4500 engine and features oleo
spring-loaded landing gear. The covering is UltraCote. The Robin
weighs 23 pounds and has graphics supplied by Rainbow Graphics
in Creswell, Oregon.
According to Bill, “It flies like a dream!”
Peregrine Freestyle 45
Edward D.J. DeLaura (4 Jefferson Dr., East Lyme CT 06333; Email:
[email protected]) engineered, designed, and
scratch-built his prototype model that he calls the “Peregrine
Freestyle 45.” He designed it to be a Pattern and Freestyle aerobatic
craft.
The model spans 53.5 inches, weighs 5 pounds, and is covered
with 21st Century film. It is powered with a SuperTigre .45 ABC
engine and uses a four-channel Hitec radio with five servos for
guidance duties.
Edward has generated full-size AutoCAD drawings for this
model and is selling them, along with a vacuum-formed cowl and
wingtips. If you are interested, please contact him.
42% Nemesis
Marty Meyer (160 Locust Ave., New Rochelle NY 10805) built
his 42%-scale version of the Nemesis racer from Wendell Hostetler
plans. It spans 106 inches and weighs 32 pounds.
The two-piece wing is joined with two carbon-fiber tubes. A
Desert Aircraft DA-100 engine, fitted with a Mejzlik 26 x 12
propeller, powers this sleek model, and it is guided by a JR radio
system.
Marty covered the Nemesis with UltraCote, and some of the
parts are finished with Du Pont ChromaBase acrylic paint.

Scratch-Built Bombay
Terry Overton (20005A 25th Ave., Shoreline WA 98115)
designed and built his unusual Bristol Bombay twin-engine British
Royal Air Force transport/bomber. The model is based on the 1938
production prototype, which was left unpainted.
Terry built the model to 11.5% of full scale, resulting in an
overall length of 95 inches and a wingspan of 132 inches. This giant
weighs approximately 38 pounds and is powered by two Enya
R120GP four-stroke engines.
Aluminum MonoKote was used for covering except for on the
ailerons, elevators, and rudders; they are covered with Solartex
silver fabric.
The model is set up so that four bombs can be released,
simulating the four 500-pound bombs that the full-scale aircraft
carried.
Modified Kadet Senior
Don Bortz Sr. (107 Crest Ct., Lake Placid FL 33852) modified
this Sig Kadet Senior by extending the wingspan from 78 to 91
inches. He also added flaps and ailerons, and he upgraded from the
suggested 40-size power plant to a Zenoah G-26 that turns a 16 x 8
propeller.
He used a cowling from a Goldberg Chipmunk kit to finish the
front end and moved the vertical fin aft 4 inches to allow for a fulldepth
rudder. The rudder modification meant that the elevators had
to be split and driven with a joiner horn.
The model is covered with Solartex and four coats of clear sealer.
“Many thanks to my good friend Don Strong, who is a great
builder/designer, for all his technical advice and help,” wrote Don.
Extra 300S
With his father Jeff’s help, it took Travis Raaberg (1842
Jefferson St., Concord CA 94521) roughly three weeks to fully
assemble this Great Planes 40-size Extra 300S.
The 6-pound model is covered with red, white, and blue
MonoKote. Travis chose an O.S. .46 AX engine for power and a
Futaba radio system for guidance.
“It was difficult to fly and take off at first, but now it is my
favorite airplane to fly!” he wrote.
Bristol M.1
Chuck Bennett (669 Baker St., Mount Gilead OH 43338; E-mail:

a 12 x 4 propeller.
The model is covered with Super Coverite, the finish is flat paint
from spray cans, and the roundels were painted by hand.
Chuck describes this monoplane as an “old reliable” in his fleet

A Keeper!
Ray Shroba III (101 Pioneer Dr., Minooka IL 60447; E-mail:
[email protected]) modified this Sig Four-Star 60 by removing all
dihedral from the wing and adding operating flaps. He also extended
the wingspan to 78 inches, enlarged the tail surfaces, and mounted
the engine on its side, allowing for a cowling to be fitted.
Ray chose a Magnum 91 four-stroke engine for power and
installed a Futaba T9CAP radio-control system. The 10-pound
model is covered with UltraCote.
“ It flies rock-solid stable, with very smooth control authority at
all speeds,” he wrote. “It has a very good roll rate with and without
flaps deployed. This one’s a keeper.”

Raptor 60 Jetranger
Ferdinand S. Custodio (11792 Wills Creek Rd., San Diego CA
92131; E-mail: [email protected]) sent in this shot of his Raptor 60
V2.0 with an old Kalt Jetranger fiberglass fuselage that he bought
from an online auction. The mechanics fit perfectly inside the
fuselage.
The modifications he made were installing the tail rotor on the
other side, running the control rod above the tailboom, and
relocating the tail servo next to the gyro.
Automotive paint was used to replicate the scheme used by
Philippine Airlines, for which his father was an avionics crew chief.
A Thunder Tiger .70 engine powers this helicopter, and it is fitted
with carbon-fiber blades, a blinki-mc4 battery monitor, and
electronics and guidance by Futaba.
First Building Project
Steve Busse’s (1030 Bannock St., Livermore CA 94551) son
Michael is shown with the Sukhoi Su 26 that he built from a Carl
Goldberg Models kit when he was 16 years old.
This was the first model that Michael ever built, and according to
Steve, he did it entirely by himself.

Brodak Hurricane
Frank Stetson (RR 3 Box 2319A, Townsend GA 31331) built
this Hawker Hurricane from a Brodak Manufacturing kit and altered
it slightly to resemble the desert version of the full-scale airplane.
This modification consisted of adding the profile of a sand filter
under the model’s nose.
Frank powers his camouflaged fighter replica with a Double Star
.40 engine that swings an 11 x 5 propeller. It is finished with Brodak
modeling dope.
“It flies great and does the full pattern very nicely,” he wrote.
Avistar on Floats
John Hansen (Tulsa OK) took this photo of Jacob MacKorell’s
(5012 Mary Ellen Cir., Smyrna TN 37167; E-mail:

Jacob made the V-hulled floats from 1-pound-density foam and
covered them with two layers of 6-ounce fiberglass applied with
West System epoxy.
Two Ernst rudders coupled with a tie rod and actuated by a
single servo provide steering for the model. An O.S. 52 four-stroke
engine swinging an 11 x 7 APC propeller powers it.
“The only change I made to the Avistar was to install a ventral
fin for added stability,” wrote Jacob.

10 MODEL AVIATION
VTOL H-Wing
Ran D. St. Clair (1048 Jones Ct., Redwood City CA 94063; Email:
[email protected]) designed and built his VTOL H-wing,
which is capable of vertical and horizontal takeoff and landing. It
spans 24 inches and weighs 5 pounds, 11 ounces, less the removable
“swing gear.”
The model is made from 4mm Coroplast and uses an O.S. .61 FX
engine with a 14 x 4 propeller. The onboard radio gear includes an
FMA Direct FS8 receiver with integrated Co-Pilot, three rate gyros,
an in-line mixer, a custom control switch (to bypass the gyros), and
a prototype FMA Direct flight recorder.
According to Ran, forward flight is “normal,” with a talent for
high-alpha Harrier maneuvers. The Co-Pilot and gyros make the
model fully stable in “hover mode,” allowing vertical takeoff and
landing by a nonexpert pilot.
Semiscale Robin
Bill Hastings (269 N. 5th St., Creswell OR 97426; E-mail:
[email protected]) built his 99-inch-wingspan Curtiss Robin
from an Old World Models kit.
It is powered by a SuperTigre 4500 engine and features oleo
spring-loaded landing gear. The covering is UltraCote. The Robin
weighs 23 pounds and has graphics supplied by Rainbow Graphics
in Creswell, Oregon.
According to Bill, “It flies like a dream!”
Peregrine Freestyle 45
Edward D.J. DeLaura (4 Jefferson Dr., East Lyme CT 06333; Email:
[email protected]) engineered, designed, and
scratch-built his prototype model that he calls the “Peregrine
Freestyle 45.” He designed it to be a Pattern and Freestyle aerobatic
craft.
The model spans 53.5 inches, weighs 5 pounds, and is covered
with 21st Century film. It is powered with a SuperTigre .45 ABC
engine and uses a four-channel Hitec radio with five servos for
guidance duties.
Edward has generated full-size AutoCAD drawings for this
model and is selling them, along with a vacuum-formed cowl and
wingtips. If you are interested, please contact him.
42% Nemesis
Marty Meyer (160 Locust Ave., New Rochelle NY 10805) built
his 42%-scale version of the Nemesis racer from Wendell Hostetler
plans. It spans 106 inches and weighs 32 pounds.
The two-piece wing is joined with two carbon-fiber tubes. A
Desert Aircraft DA-100 engine, fitted with a Mejzlik 26 x 12
propeller, powers this sleek model, and it is guided by a JR radio
system.
Marty covered the Nemesis with UltraCote, and some of the
parts are finished with Du Pont ChromaBase acrylic paint.

Scratch-Built Bombay
Terry Overton (20005A 25th Ave., Shoreline WA 98115)
designed and built his unusual Bristol Bombay twin-engine British
Royal Air Force transport/bomber. The model is based on the 1938
production prototype, which was left unpainted.
Terry built the model to 11.5% of full scale, resulting in an
overall length of 95 inches and a wingspan of 132 inches. This giant
weighs approximately 38 pounds and is powered by two Enya
R120GP four-stroke engines.
Aluminum MonoKote was used for covering except for on the
ailerons, elevators, and rudders; they are covered with Solartex
silver fabric.
The model is set up so that four bombs can be released,
simulating the four 500-pound bombs that the full-scale aircraft
carried.
Modified Kadet Senior
Don Bortz Sr. (107 Crest Ct., Lake Placid FL 33852) modified
this Sig Kadet Senior by extending the wingspan from 78 to 91
inches. He also added flaps and ailerons, and he upgraded from the
suggested 40-size power plant to a Zenoah G-26 that turns a 16 x 8
propeller.
He used a cowling from a Goldberg Chipmunk kit to finish the
front end and moved the vertical fin aft 4 inches to allow for a fulldepth
rudder. The rudder modification meant that the elevators had
to be split and driven with a joiner horn.
The model is covered with Solartex and four coats of clear sealer.
“Many thanks to my good friend Don Strong, who is a great
builder/designer, for all his technical advice and help,” wrote Don.
Extra 300S
With his father Jeff’s help, it took Travis Raaberg (1842
Jefferson St., Concord CA 94521) roughly three weeks to fully
assemble this Great Planes 40-size Extra 300S.
The 6-pound model is covered with red, white, and blue
MonoKote. Travis chose an O.S. .46 AX engine for power and a
Futaba radio system for guidance.
“It was difficult to fly and take off at first, but now it is my
favorite airplane to fly!” he wrote.
Bristol M.1
Chuck Bennett (669 Baker St., Mount Gilead OH 43338; E-mail:
[email protected]) built his 63-inch-span Bristol from a Balsa
USA kit and powers it with a Tower Hobbies .46 engine that swings
a 12 x 4 propeller.
The model is covered with Super Coverite, the finish is flat paint
from spray cans, and the roundels were painted by hand.
Chuck describes this monoplane as an “old reliable” in his fleet
of models.
“This predictable slow flyer has suffered only a few mishaps in

the day he performed his first loop.
Several weeks earlier, Scott and his mother came to the Ned
Brown Woods facility, the home field of the Chicagoland Circle
Cutters, and learned to fly using a club-owned Cox PT-19 trainer.
He was so keen on flying that the club members presented him with
this Ringmaster that Al Onkin built. Within a week of receiving the
Ringmaster, Scott had performed his first loop.
Martin PBM-5
Herb Hall (1842 Tattenhall, Houston TX 77008) crafted this
rarely modeled Martin PBM-5 flying boat. It spans 11.5 feet and is
powered by two Magnum 91 four-stroke engines.
The model is fitted with a JR radio, features working flaps, and
has working cabin and navigation lights. Herb built it from foam,
balsa, and plywood. It is covered with printer’s aluminum and
features complete rivet detailing.
Herb offers plans for this behemoth; please send inquiries
