LEROY HEIKES (Plainwell MI)
submitted a report about the First Annual
CL Scale Competition of the West
Michigan Smoke Rings club. According to
Leroy the club was in existence only
roughly a year and a half at the time of the
contest—June 24, 2006—which was an
effort by the club members to promote CL
Scale in their area.
The contest included F4B, Sport,
Profile, and Fun Scale divisions, with a
Junior category in the Profile event. The
competition was held in the Plainwell
High School parking lot, where the fliers
enjoyed a fine macadam paved area on
which to fly. There is nothing like a
smooth surface from which to perform
great takeoffs and landings, making Scalemodel
flying more enjoyable.
The club had a total of 18 competitors,
with five entries in Sport and Junior
Profile. Among the contestants was the
Bauer family out in full force with
Charlie, Jason, Aaron, Peter, and Kathy—
who placed well in the Sport, Profile, and
Junior Profile events—in attendance.
Charlie placed first in the Sport event
flying a Gee Bee racer. Mindy Alberty
placed first in Junior Profile and Kathy
Bauer was first in Profile.
Among the other winners were Chuck
Snyder in F4B with his Hs 129, R. Garret
in Fun Scale with a triplane, and Justin
McCauley in Junior Fun Scale flying a
Brodak trainer.
Leroy was the CD, and he thanks the
Plainwell High School authorities for
allowing the club to hold the contest at
the site and use the restroom and
concession facilities. It will hold the
second annual meet at the school June 30,
2007.
This competition will, again, afford
Scale modelers in Michigan and
surrounding areas with an opportunity to
compete. Why not come out and provide
your support as a participant or a
spectator to see a great day of CL Scalemodel
flying?
Simulating Corrugations on Flying
Surfaces: I received an E-mail from Tom
Telesca announcing that he just
completed an L-19 Bird Dog. He had a
hard time creating the corrugations on the
flying surfaces and wondered if there
might be a better way. His method was to
use string and hardwood or balsa strips.
Tom noticed the picture of Karl Georg
Krafft’s Boeing 100 in the October
column. The text read that the
corrugations on the model’s flying
surfaces were simulated using corrugated
cardboard. An E-mail to Karl Georg
brought the following information.
The corrugated cardboard is the type
used for decorations and wrapping
presents, comes in many colors, and can
be found in craft-type stores or those that
sell paper goods. The cardboard is
roughly 2mm thick and the corrugations
are approximately 4mm apart measured
from top to top of the corrugations.
To meet the scale of the corrugations
for the Boeing 100, Karl Georg had to cut
away every other corrugation. Then he
glued the cardboard onto balsa parts and
did some filling, sanding, and painted the
same.
The lengths to which modelers go and
the ingenious things they come up with
during the process of building their
models never ceases to amaze me. The
craft-type stores mentioned in the
preceding can also be a great source for
many other things we use in our models.
I like to wander up and down the
aisles that contain all sorts of pins and
fasteners. In addition to finding “T”-type
pins that most of us use during model
construction, there are pins with round
heads that come in many sizes and colors.
They are good for simulating control
handles in the cockpit. You will also find
many types of transferable lettering that
can be used to apply the finishing touch
to a model.
The next time you get the opportunity
to go to a craft store, don’t pass it up.
Walk the aisles and let your imagination
and a little ingenuity help you discover
some useful items.
Hiding the Elevator Pushrod Revisited:
In the June 2006 column I wrote about a
method Clancy Arnold uses to hide the
elevator pushrod inside a profile fuselage.
This month I’m featuring Ronald
Peterson’s (Indianapolis IN) “Layer
Laminated Technique” he used to make
his 2005 Nats-winning profile
Messerschmitt Bf 110 and Rockwell OV-
10 Bronco that are shown.
The Messerschmitt Bf 110 was
designed in 1934 for use by the Luftwaffe
as a long-range strategic fighter. It was
too heavy for that role but was accepted
as a fighter-bomber, reconnaissance
airplane, and a night fighter: its most
successful job. Approximately 6,000
various models were produced.
Ronald’s Bf 110 has a wingspan of 56
inches and is powered with two HP .40
Gold Cup engines. It features a five-line
control system: three lines for elevator
and throttle control, and the fourth and
fifth lines for two sets of bomb drops.
The US Air Force, US Navy, and US
Marines used the Rockwell OV-10
Bronco from the late 1960s through the
early 1970s as an armed tactical
reconnaissance airplane that took part in
anti-insurgent operations. The Bronco
was also exported and used by Germany,
the Royal Thai Air Force, Venezuela, and
Indonesia.
Ronald’s OV-10 Bronco has a
wingspan of 47 inches, a length of 44
inches, and is powered by two HB .21
engines. Control is via a two-line system,
and a Clancy Arnold electronic system is
used for throttle and tank drop.
The fuselages of Ronald’s profile
models take advantage of the 1-inch-thick
rule for profile fuselages that provides
room for hiding the elevator pushrod. His
airplanes’ fuselages are made from three
layers of sheet balsa: one center layer is
1/2 inch thick and two outer layers are 1/4
inch thick. The accompanying sketch
shows how the Bf 110’s fuselage was
made.
The first step is to cut all three balsa
sheets to the fuselage shape of the model
you are making, including the wing
cutout. Complete the wing and stabilizerelevator
assembly. The wing should be
sheeted (at least in the center-section) and
have the elevator pushrod installed in the
wing bellcrank.
Temporarily fit the wing and
stabilizer-elevator assembly to the 1/2-
inch fuselage sheet and mark the area in
which the elevator pushrod will travel. Be
sure to leave sufficient clearance for the
pushrod movement.
Cut the marked area from the 1/2-inch
sheet and glue the remaining pieces to the
inboard 1/4-inch sheet. At this point you
can mount any kind of nose landing gear
or tail-wheel assembly.
Final assembly is accomplished by
gluing the outboard 1/4-inch sheet in place
(sketch #1). At this point the fuselage can
be sanded and given its final shape.
When installing the wing, push the
elevator pushrod up into the fuselage so
the elevator horn can be attached, and
then move the wing forward and glue it in
place (sketch #2). At this time the
stabilizer-elevator assembly is not glued
in place. When the wing-fuselage glue
joint is dry, the stabilizer-elevator
assembly can be adjusted to a neutral
position and glued in place.
The laminating procedure Ronald used
works best on low- and high-wing
aircraft, but it can be modified for use
with midwing models by cutting out part
of the fuselage under the wing and
reinstalling the part after the wing is
installed. Hiding the pushrod gives a
profile model a cleaner and more
scalelike appearance.

CL Scale events, contest reports, and
especially photos of CL Scale activity to
