COVERING MATERIAL
Your SIG CAP 231EX ARF kit has been expertly covered with #819
Dark Yellow Carl Goldberg Models ULTRACOTE®.
Before
leaving the factory, all covered parts were inspected and cleaned
before being packed. Upon opening your kit you may find that the
covering has relaxed in some areas, requiring reshrinking. This is
perfectly normal and has nothing to do with the covering material
or how it was applied. It has to do with the wood beneath the
covering. Wood takes on or loses ambient humidity. Your CAP
ARF was manufactured in a relatively humid region of the world.
The wood was therefore holding humidity at the time the parts
were covered and bagged. Once the parts are removed from their
bags and subjected to drier conditions, the wood quickly loses
moisture and the covering may appear loose. This also explains
why most iron-on coverings stay tight in the summer only to loosen
a little in drier winter conditions.
We suggest you use a heat gun and/or a cloth-covered iron to
completely go over the various covered parts of your CAP, making
sure the covering is drum tight and that every seam is well
adhered. Be sure to follow Goldberg's suggested heat settings for
ULTRACOTE® to avoid damaging the covering.
INSTALLING HINGES
As mentioned, the CAP 231EX is a large airplane with large,
powerful flying surfaces. This means that the hinges used to attach
these flying surfaces must be up to the task.
For this
reason, we have included SIG's famous Double X Pinned Nylon
Hinges for use with this model. Properly installed, these hinges
are extremely smooth in action and very strong. The effort involved
in mounting these hinges will be more than compensated by the
close fit, smooth action and the peace of mind you have when
flying this airplane.
The hinging procedure is the same for all flying surfaces - ailerons,
elevators and rudder. This manual will tell you when to hinge
the various surfaces - DO NOT hinge surfaces ahead of time,
unless instructed to do so. Note that each flying surface and its
corresponding installation point have been pre-slotted at the
factory for your convenience.
Ailerons require four (4) hinges
each, elevator halves require three (3) hinges each, and the
rudder uses three (3) hinges, for a total of 17 hinges and hinge
pins. These are provided in a separate bag in your kit.
Begin by using a hobby knife to completely open up and clear each
pre-slotted hinge openings. These slots need to be 1" wide to
accept the width of the hinges and about 5/8" deep on each side.
Next use a short length of thin saw blade material (such as a piece
of Dremel® saw blade) to open the width of the slots even further
to accept the thickness of the nylon hinges.
Assemble the hinges by inserting a hinge pin through the center
holes of both interlocking halves. Once the hinges are pinned, use
a pair of needle nose pliers to bend the sharp end of the pin
90°, as close to the hinge joint as possible, without binding it.
Pre-assemble all hinges in this manner.
Next, use a sharp #11 blade in your hobby knife to countersink the
round "knuckles" of one of the hinges into the beveled edge of the
flight surface (ailerons, elevators and rudder).
Simply insert a
hinge into the flight surface until it bottoms out on the edge of the
bevel. Use your hobby knife to then cut a slot on each side of the
hinge knuckle to a depth equal to the knuckle (about 1/8").
Remove the hinge half and use your knife to cut the rest of the
balsa and covering away from the hinge slot, allowing the hinge
knuckle to recess into the flying surface. Repeat this process for
each hinge slot location on each flying surface.

MODELER S TIP : One of the most common problems
associated with shrinking any covering film is controlling the
heat around seams. Heat applied close to or directly onto
seams re-heats the covering adhesive and the seam will often
"crawl". This is easy to control. Just tear a few paper towels
into strips and soak them in cool tap water. Lay the wet strips
over any covering seam and use your heat gun or iron as you
normally would. The wet strips keep the seam cool while the
covering immediately next to it shrinks. This tip works great
with any iron-on covering.
IMPORTANT NOTE : There are left and right ailerons. You
can easily tell which aileron belongs with the proper wing
by the fit and noting the plywood hardpoint plate for the
aileron horns on the bottom of each aileron. The outline of
this plate is easy to spot through the covering. It lines up with
the aileron servo hatch on the bottom of each wing panel.
The elevator halves are symmetrical and each has a
plywood hardpoint plate on both sides, allowing them to be
mounted on either the right or left side of the horizontal
stabilizer.
