62 MODEL AVIATION
Focal Point
Mike Donovan (1710 Warrenton Rd., Vicksburg MS 39180; email:
[email protected]) built this Dreadnought for CL
Precision Aerobatics from Randy Smith plans.
The model is covered with silk and Randolph dope. Power is a
Ro-Jett .40 RE engine.
“Only a few flights so far so it’s not fully flight trimmed, but I
think it has great potential,” wrote Mike.
Dreadnought
Robert Yurkowski (1617 N. Oneida Ct., Mount Prospect IL
60056) built this 1936 Miss America, which Frank Zaic designed.
It spans 84 inches and weighs 6 pounds. A 26-year-old Kraft MK
IV transmitter and Kraft receiver control the model.
Robert uses an O.S. .55 AX engine for power, with an APC 13 x
6 propeller.
“The model is very easy to construct and is a great flyer with a
beautiful glide,” wrote Robert. “I believe this model was ahead of its
time.”
This model that Herman Grooters (7045 Michael Dr.,
Hudsonville MI 49426; e-mail: [email protected]) constructed
is based on Don Srull’s .15-powered project featured in the May
1979 MA.
Herman scaled the plans up to produce an 843/16-inch wingspan
and to be powered by a Magnum .91 four-stroke engine. He doubled
the wood sizes from the specifications on the plans.
He wrote:
“I did move the firewall back, and increased the length of the
cowl to compensate for the longer length of a four-stroke engine.
“Performance is outstanding and as with Don’s original, ‘slow
scale-like flight, easy takeoffs and landings, and super touch-andgoes
are its stock in trade.’ Spectators always pause to take shots of
this model.”

This original Lou Andrews Aeromaster is the first model that
Woody Brammer (150 General Eddy Tr., Tryon NC 76106; e-mail:
[email protected]) built from plans. He used the plans set
and hardware that a close friend had in his attic.
The Aeromaster is covered with silk and dope and painted with
Krylon spray. Guidance is via the 2.4 GHz Futaba FASST system,
and a Saito FA-65 FS engine hauls the model around.
“It flies great and is one of the most fun planes I have ever had in
my 40+ years of flying models,” wrote Woody.

William Schmidt (1944 Billings Dr., Bismarck ND 58504; email:
[email protected]) built his DR-107 One Design from
Radio Control Modeler plans (set 1183).
The 72-inch wingspan stayed the same, but William lengthened
the fuselage 3 inches and moved servos to the tail for the rudder and
elevator. Tail surfaces were sheeted so that flying wires could be
omitted, and he reinforced the landing gear block. The firewall was
thickened by 1/4 inch, for additional strength.
The cowl, canopy, and wheels are from Fiberglass Specialties. A
Fuji-Imvac 50cc gas engine provides the power.
“It flies fast, lands easy and is very aerobatic,” wrote William.
It took Nick Kolias ([email protected]) nearly three
years to complete this MD500E that he constructed from a heavily
modified Vario kit.
Control is via a JR 12X radio system with dual receivers, into
an Emcotec DPSI Twin power supply. A JetCat PHT3 turbine
provides the power.
The helicopter’s rotor span is 6 feet, its overall length is 90
inches, and it weighs 42.5 pounds fully fueled.
“The machine handles great and it’s a barrel of fun to fly,”
wrote Nick. “Very smooth and very stable.”
A lex M artinez (12601 Edgemont Ln. #33, Garden G rove C A
9284 5; e-m ail: luv2 fish alex@ aol.com) co mpleted this, his lates t
project, on his 50th bir thda y.
The Bl ue Max World War I model spans 67 inc hes. It featu res
5-inch wi re-s poke w hee ls, a full-bo died 1 2-in ch pilot, and 7-in ch
Spandau m achine gu ns.
The K MS Qua ntu m 4120 /05 brush less o utrunner moto r swings
an APC 13 x 6E p ropeller that Alex co lored with a brown Sha rpie
mar ker. A four-cell, 4200 mAh L i-Poly ba ttery and an 80-a mp
ESC are us ed.

Lawrence Margolin (70-12 Kissena Blvd. Apt. 120b, Flushing
NY 11367) has been designing models for 30 years. This is his
latest effort: a Twin Boom 2 Rudder Pusher.
Mounted on a pedestal, the glider is released by a simple pin
mechanism that the glider pilot controls. This was Lawrence’s
first project using electric power.
The Pusher spans 48 inches and uses a 30-35, 1,100 Kv, 350-
watt motor with a three-blade propeller and four A123 batteries.
The ESC is a 40-amp unit.
The glider is a Fling ARF from the Tower Hobbies catalog.
