Control Line Navy Carrier - 2011/01

January 2011 135
IN THE LAST column I promised to include
information about the new Carrier models that were
flown at the Nats this past summer.
There were five new designs in the Nostalgia events. Burt Brokaw
had a couple of Jim Womack designs from the early 1970s. Not only
were they Jim’s designs, but they were models that he built and Burt
refurbished for competition.
Burt entered a Grumman Guardian in Class I. Spanning 31 inches,
it was slightly larger than the Bill Netzeband Guardian from 1962.
The Guardian was built from published plans, but specific information
about that airplane has been lost after nearly 40 years. Burt used a
K&B 40R engine for power.
Burt’s other entry was Jim’s profile T-28, which is now flown
with a Thunder Tiger .36 engine.
In addition to the diminutive Domizi Guardian that Ted Kraver
entered in Class I, he flew a 32-inch-span Curtiss F6C Hawk biplane
in Class II that Marvin Martinez originally
built. Power was provided by an O.S. .60
Gold Head engine.
Everett Shoemaker entered Class II
Nostalgia with a new Nakajima C6N1 Myrt
that Roland Baltes designed and had
published. It was featured in the May 1976
MA. The 35-inch-span model weighed 53
ounces and was pulled around by a K&B
.61 engine.
In Nostalgia Profile Carrier I entered my
A-4P Skyhawk design from the April 1973 American Aircraft
Modeler. It flew with a SuperTigre ST .35 engine. Roger Edwards
originally built that particular Skyhawk.
This year there were more entries in Nostalgia at the Nats than in
any year prior. And the competition was great, even though some
contestants elected not to fly because of the wind.
I mentioned Jo Shoemaker’s new Fi 167 in the previous column,
but Everett Shoemaker also had a new model: a Fairey Fulmar for the
electric-power Class II Carrier event. The updated version is based on
his glow-powered Fulmar design.
Everett’s updated aircraft has 315 square inches of wing and a
43.5-inch span. He powered it with an E-flite Power 46 outrunner
motor that was driven by a Thunder Power five-cell, 3850 mAh Li-
Poly battery and managed by a Castle Creations Phoenix 60 ESC.
I’ve mentioned quite a few models this month. I’ve also
shortened the text, to allow for an additional photo, but I can’t
include pictures of all of the aircraft. You can see those that are
not shown here in the July 15 edition of NatsNews, which you
can find on the AMA Web site.
Below: Burt’s Nostalgia Profile model is this T-28, which is
also a Jim Womack design, circa 1972.
This shows the internal layout of John
Vlna’s custom handle for electric-powered
CL Carrier, as described in the column.

at the 2010 AMA Nats. It’s a model that Jim Womack originally built.

• Electronic throttle control
The author’s A-4P design won Nostalgia Profile Carrier at the
Nats. It is powered by a SuperTigre ST .35.

136 MODEL AVIATION
Electronic throttle control has been a reality
in RC for decades, and it is more recently
catching on in CL. The possibility of
electronic control of a conventional glow
engine in Carrier models is real with a few
control systems.

In previous columns I’ve written about the
U/Tronics units that Clancy Arnold has
available. He designed the single-channel
U/Tronics systems to be installed in the aircraft
with the resistor at the handle. Motors don’t
require a servo as glow engines do, because the
U/Tronics (or any other control system) can
drive the power plant’s ESC directly.
John Vlna has been experimenting with
lightweight electric-powered CL designs and
has recently been applying his experiments to
small electric Carrier models. By small I mean
with 150 square inches of wing area, so they fit
into the .15 Carrier class.
Where John’s models differ from other .15
Carrier airplanes is in weight; his come in at
less than a pound ready to fly. Every fraction
of an ounce counts at those weights, so John
has moved as much bulk off of the models as
possible.
He puts not only the resistor, but also the
batteries and the U/Tronics control system in
the handle. The signal to control the ESC goes
through the insulated lines. With only the ESC
to control and no servo, there is no need for a
“receiver” battery—only the primary power
battery.
John has summarized his work in the
October issue of the Navy Carrier Society’s
High-Low-Landing newsletter. If you aren’t a
member, you can join and receive the
newsletter by contacting Secretary-Treasurer
Ted Kraver at the addresses listed at the end of
the column. MA

Keeping watch over the 1,100-acre National Flying Site in Muncie,
Indiana, is a formidable task. Borrowing a page from the National Park
Service and many successful state park programs, the Academy is
seeking retired volunteers to become flying-site hosts.
