Marty Meyer (160 Locust Ave., New Rochelle NY 10805)
assembled this Extra 300S from a Kangke ARF kit.
Originally designed to be powered by a two-stroke .40-.60
engine, he converted the 58-inch-wingspan model to electric power.
Marty installed an E-flite 46 outrunner motor. Two 3850 mAh
battery packs are used in series to yield 22.2 volts.
“That was the largest size battery pack that I could fit in the
fuselage,” he wrote.
A Futaba 7UAP radio system handles the guidance duties, and
the Extra weighs 7 pounds, 6 ounces.
Mark Souers (12 Westwood Dr., Long Lake MN 55356; E-mail:
[email protected]) constructed this T-34 from a Top Flite Gold
Edition kit.
The model is powered by an O.S. 1.20 four-stroke engine and
has a wingspan of 80 inches. Guidance is via a JR XP7202 sevenchannel
radio.
Operating features include flaps and Robart retracts. The model’s
flying weight is 14 pounds, and it is covered with UltraCote.
“I used the official colors of the Navy trainer my brother flew
during his naval career,” wrote Mark.

Charles B. Collins (170 Pheasant Run Dr., Chagrin Falls OH
44022) scratch-built this 1/8-scale Aeronca from the 1957 Berkeley
kit plans. The original plans called for a tube receiver and two
escapements, but he wisely substituted modern RC gear in the form
of a Futaba system.
Instead of using the original design’s glow power, Charles
converted the C-3 to electric power and installed an AstroFlight 020
motor and a three-cell battery.
“The C-3 had the original lightplane braking system,” he wrote.
“The pilot wore leather gloves and if he wanted to turn while taxiing
he reached out and grabbed a wheel.”
T.J. Robert (2810 Alibi Dr., Lake Havasu City AZ 86404)
designed and scratch-built this model he calls “Pogo.” Its purpose is
to fly off the water at the Havasu Sport Flyers Association flying site
at Lake Havasu Rotary Park.
The model spans 92 inches and features flaps and NASA-type
“droops” on the LE for extra lift. It sits on 48-inch-long Sig
Manufacturing floats and weighs 23 pounds.
Power is supplied by a highly polished Fox 4.2 cu. in. gas engine
that swings an APC 24 x 10 propeller. A Hitec Eclipse 7 radio
system is used for guidance, and eight servos are onboard.
“The maiden/test flight went surprisingly smooth, with only a
little up-elevator trim needed at half throttle,” wrote T.J.

John E. Olson (E-mail: [email protected]) built this 1/7-
scale Avenger from a Skyshark R/C kit.
The model weighs 13 pounds and spans 72 inches. It is
completely planked with 1/16 sheet balsa and covered with 3/4-
ounce fiberglass.
John used the Nelson System Three epoxy to apply the
fiberglass. After sanding and priming he used Rust-Oleum spray
paints to finish the model.
A Futaba eight-channel PCM receiver is used, and there are
nine servos onboard. A SuperTigre .90, fitted with a Brison
muffler, provides the power. The main retracting landing gear is
by Spring Air, and the retracting tail wheel is a Robart unit.
“On the maiden flight it took a lot of runway because of its
weight, but once in the air it flew great,” wrote John.
Lester A. Thompson (135 Hearthside Rd., Standish ME 04084)
built this Astro-Hog as a tail-dragger from a Sig Manufacturing kit.
It spans 71 inches and is powered by an O.S. FL-70 four-stroke
engine. Most of the model was covered with MonoKote, but the
bottom of the wing was covered with 21st Century Fabric, “Just
because I had it!” wrote Lester.
The model is guided via a Futaba T6XA radio system. The
Astro-Hog was a popular RC Aerobatics design from the late 1950s,
and it still makes for a great sport RC model.

“In 1972 a good friend and his dad owned a 1966 Piper
Cherokee 140B and gave me my ‘first ever’ airplane ride,” wrote
Bill Thomas (23 Winfield Rd., Erial NJ 08081; E-mail:
[email protected]). “That ride inspired me to obtain my
private pilot’s license.”
Bill purchased a Hangar 9 Cherokee ARF, removed the
covering, and re-covered it with MonoKote to re-create the paint
scheme of a 1966 Piper Cherokee 140B. Then he added the same
identification numbers his friend’s Piper had: N6895W.
The model is powered by an O.S. .52 Surpass four-stroke engine.
“It gets a lot of attention at the field,” wrote Bill.

James Nelson (Box 87, Hayfield MN 55940; E-mail:
[email protected]) scaled up Carl Goldberg Models’
Tiger 2 plans to double the original’s size and produced what he
calls a “Tiger 2 x 2.”
The giant Tiger is powered by a Steil 5.6 gas engine, which
turns a 24 x 10 Zinger propeller. A JR radio system is used in
conjunction with Hitec servos.
The model spans 10 feet, 6 inches, and is more than 8 feet
long. It weighs 30 pounds and is covered with MonoKote.
“It flies every bit as well as the normal size Tiger!” wrote
James.
