date on progress as the deck takes
shape.
He has his sights set on establishing
a Carrier contest at the Tillamook Air
Museum in Tillamook on the Oregon
coast west of Portland. The museum
has a number of U.S. Navy carrier
aircraft on display, including one of the
relatively few remaining AM-1 Martin
Maulers.
The museum is housed in a former
Navy blimp hangar. Constructed from
wood and covering 7 acres of floor
space with a height of 192 feet, the
hangar itself is something to see, even
without the aircraft!
The 2013 Rules Proposals
The 2013 rules cycle includes
proposals to allow the use of radio
signals (2.4 GHz spread spectrum)
for controlling functions other than
elevation on CL models. By the time
you read this, there may be other
variations.
As I write this, I don’t know what
specific form the final proposals will
take. If you are interested in these rules
or others proposed in this cycle, now is
the time to comment to your Contest
Board members. The AMA website
contains information about proposals,
schedules, and how to contact your
Contest Board representatives for the
various events.
Using a radio for controlling throttle
and other auxiliary functions (not the
elevator) makes possible some changes
in the basic concept of our CL Navy
I ’ve received correspondence from John Lickley (Oregon), who is new to
Carrier flying and is enjoying the contest activities in the Pacific Northwest.
Two of the photographs this month are of his aircraft.
The MO-1 Profile is near and dear to my heart. It was built from the Golden
State kit which I designed. John chose a Thunder Tiger .36 for power.
John’s Nakajima C6N1 Myrt is a Roland Baltes design and one of the classics of
our event. It was originally published in the May 1976 issue of MA as a Class II
model. With a K&B 8011 front-intake .40 engine,
it is ideally suited to the Nostalgia event, as well as
serving as John’s introduction to AMA Class I Navy
Carrier.
When he started flying Carrier, John noticed the
weight and size of most traditional carrier decks
used in our events. He has undertaken a significant
weight-reduction project. He plans to use thin
plywood sandwiched around a foam core as the
primary construction material for a new deck he is

Carrier models. It certainly simplifies
control installations by eliminating
the need for our traditional three-line
control systems.
We’ve always had the option of
using two-line and even monoline
control systems in our Carrier models,
but they haven’t been practical in the
past because of the requirement that
all control functions be accomplished
through the lines.
Mechanical controls using line
tension (the current method) require
one more line than the number of
functions to be controlled. That pretty
much rules out mechanical controls
other than three-line systems, but there
have been some good developments
in electronic controls with the signals
passing through the lines. The use of
radio signals eliminates the need for
insulated lines.
The current rules specify two-line
and monoline diameters that are larger
than required to meet the AMA safety
guidelines for line strength. That was
done to further discourage the use of
such systems by removing some of the
advantage of reduced line drag. Even
with the larger line diameters, there is
still an advantage in drag, and line drag
is a relatively large proportion of total
drag on our Carrier models.
It will be up to the Navy Carrier
Contest Board to determine how to
proceed in our events—with your
guidance. If this issue is important to
you, contact your board member to
voice your opinion.
.15 Carrier
.15 Carrier has seen some interesting
developments in the last year. John
Vlna introduced an electric-powered
Supermarine Seafire Mk 46/47 at the
2011 Nats. It has an interesting stepped
airfoil, designed specifically for foam
construction.
The model is constructed from 3/8-
inch thick pink insulation foam with
some carbon-fiber reinforcing tubes
in the fuselage and wing. The model
was in raw foam last summer, and
was definitely striking in its pink color
scheme! It has since been painted and it
looks nice.
The model is electric powered, using
a Turnigy 3530-1400 motor with a fourcell
2200 mAh battery pack. It weighs
26 ounces and John lists the wing area
at 260 square inches, making it slightly
larger than most .15 Carrier models. It
flies on two lines with the speed control
function transmitted through the lines
from a controller in the handle to the
model’s ESC.
Especially for electric-power
applications, foam construction may
offer a lightweight alternative to more
conventional construction materials
and methods. With reduced vibration
and no fuel to soak things, foam could
offer some advantages.
Eric Conley has been scoring quite
well in .15 Carrier with his electricpowered
model. I don’t have many
details of the model as I write this,
but I hope to be able to get some
photos and other information at the
Southwest Regionals in Tucson to
share with you.
One characteristic that I have been
able to confirm from descriptions I’ve
received is that it is big. Traditional .15
Carrier models usually have between
220 and 250 square inches of wing
area. With a larger wing area, and
lightweight construction, the wing
loading on Eric’s model is lower than
usual for such models.
Lower wing loading translates
directly into better low-speed
capability. Eric has been achieving
low speeds close to 5 minutes, which
is quite good compared to more
traditional .15 Carrier models. With the
success Eric is having with his larger
model, he could be starting a trend.
