R. Lynn Hendry (840 Grelle Ave., Lewiston ID 83501; e-mail:
[email protected]) converted an A6M5 Zero (a Global ARF by
Vinh Quang R/C Models) to this “Rufe” floatplane per Guillow’s kit
507.
“The Rufe center float and sponsons came out very well with the
scale up effort,” wrote R. Lynn.
The finished airplane weighs 7 pounds, 4 ounces. The wingspan is
62 inches, with an overall length of 45 inches. The model uses an
Evolution .46 engine and a remote glow igniter. Engine and static tests
have been completed. Control is via an Airtronics 2.4 GHz radio.
Raina Pintamo holds the Lil’ Delta that John Hoover (2874
Beland, Keego Harbor MI 48320; e-mail: [email protected])
created by using a ParkZone P-51 Mustang motor and gearbox.
The model spans 14 inches with a weight of 32 grams. A
Spektrum 6400 receiver plus a 1.5-gram linear servo gives the
airplane full four-channel control. The landing gear is from a
ParkZone Vapor.
“The airframe is made from 2-mm Depron with a 2-mm foam
step across the high point of the top of the wing,” wrote John. “The
model is a very solid micro flyer and really grooves along the indoor
soccer arena we fly at.”
Bill Jones (351 Braeloch Rd. N., Kelowna, British Columbia,
Canada V1W 4J2; e-mail: [email protected]) built his Sig Kadet LT-
25 kit for electric power and made several modifications.
“Instead of the .25-.32 cu. in. two-cycle glow engine that is
suggested for the model, I built it with electric power, installing a
Scorpion 3026-12 motor, a Castle Creations Phoenix 80 ESC and a
separate 10 amp CC-BEC,” he wrote.
The airplane is flown with an APC 14 x 7E propeller and is powered
by a Thunder Power four-cell, 4200 mAh battery. The model’s all-up
weight is 4.7 pounds, which works out to 96 watts per pound—more
than adequate for spirited flight and basic aerobatic maneuvers.
Bill wrote:
“During construction, the main wing dihedral was reduced to 3°
rather than the specified 6°, making the plane more agile. It is covered
in MonoKote with hand-cut MonoKote trim. The plane now has more
than 40 flights on it, has no bad habits, and is a true pleasure to fly,”

Rufe Bob Shadroui (2060 Marilyn St., Clearwater FL 33765; e-mail:
[email protected]) built his XFY-1 Pogo VTOL from
blue foam and his plans.
The model was finished with two coats of liquid sheeting and
paint. A Himax Contra-Rotating motor system provides power with
an 11 x 8 tractor and 12 x 6 pusher propeller. The control system is
assisted by an FMA Direct Co-Pilot II. The XFY-1 spans 30 inches
and reaches a height of 42 inches when sitting on its tail.
“The wing loading was quite high and it was hard to launch by
hand,” wrote Bob. “The plane did have two successful flights, which
included vertical hover, but after several crashes the project was
abandoned.

Paul Stahlhuth (3599 Stockwood Way, El Dorado Hills CA 95762;
e-mail: [email protected]) began developing Joined Tip Tandem
Wing (JTTW) designs after retiring from the aerospace industry in
1991. Those include Slope Soarers, hi-start gliders, and electricpowered
models.
The JTTW shown spans 55 inches and weighs 51 ounces. An E-flite
Park 450 outrunner motor, 1350 mAh battery, and Castle Creations
ESC provide power. The elevator spans the inner half of the forward
wing, and full-span ailerons on the aft wing are coupled to semispan
ailerons on the tips of the forward wing. The rudder is coupled with the
nose gear.
Paul wrote:
“I have developed a reliable CG location for these tandem wing
designs and the joined tips provide torsional rigidity for lightweight
high aspect ratio wings. They are easy to fly, even with my 83-year-old
thumbs. This plane wants to thermal and floats through landings.”
Larry Dudeck (74 Bragg Ct., Williamsville NY 14221; e-mail:
[email protected]) built this sport-scale F-89 Scorpion from
his own design.
It features all-balsa construction with pink foam for the nose and
canopy. The wingspan is 50 inches, and the Clark Y airfoil has 434
square inches of surface. Covering is silkspan and UltraCote.
The model is powered by twin MF480 electric ducted fans driven
by HET 3W brushless motors and powered by a four-cell, 3300 Li-Poly
battery. Servos are Hitec HS-81s with a Berg four-channel receiver.
“The Scorpion was designed for bungee launch and took about 125
hours to build, which included the drawing of the plans,” wrote Larry.
Tony Loomis (23 Overlook Dr., Ridgefield CT 06877; e-mail:
[email protected]) built his One-Night 28 from Peck-Polymers.
He wrote:
“Stick and tissue model aircraft have been a love of mine since I
was a kid. I also like technology and can remember wishing I had
enough money to afford even a primitive RC system. Now technology
has moved ahead to the point where RC and stick and tissue can be
“easily combined.”
The model uses a Spektrum AR4600 receiver, and Tony employed
leftovers from his ParkZone Sukhoi Su-265m to provide a motor.
“Flights are gentle with rubber-power like climb and glide,” wrote
Tony. “I also have a rubber propeller and nose block so that soon I will
try rubber-powered RC.”
Larry K. Laughlin (8640 Shoup Rd., Colorado Springs CO 80908;
e-mail: [email protected]) assembled this turbine-powered
F/A-18 Super Hornet that he originally acquired as a “deluxe primer
kit” through BVM Models.
A JetCat Titan SE engine provides plenty of thrust. Larry logged
more than 90 flights and even won a contest with the model while it
was still in primer gray. He eventually finished it with Wandabase and
clear-coat automotive paint in January 2010, nearly duplicating the
Australian RAAF Hornet 20th-anniversary paint scheme. Graphics are
from Aeroloft.com.
The F/A-18 weighs almost 36 pounds and spans 68 inches. Larry
flies with his JR10X/Weatronic system, three Duralite Li-Ion battery
packs, and piles of high-end JR servos.
“It’s plenty sexy while sitting on the ground; however, when flying
it’s got an amazing look while in circuit at slow flight, with flaps and
gears down, carrying 75% thrust to land,” wrote Larry. “She’s a real
heartthrob.”
