Once your iron is set to the correct temperature, go over the entire
framework of the airplane, making sure that the covering is se-
curely bonded to the structure everywhere the covering comes in
contact with the wood underneath. This takes some time, but is
worth the effort.
After you have all the covering secured onto the solid areas, turn
the temperature of the iron up to approximatelly
300
O
F - 320

. This is the correct temperature for shrinking the
covering material.
Use the iron to tighten up any wrinkles in the “open” areas of the
model (no wood underneath the covering). Glide the iron over the
wrinkle for a few seconds, then remove. Repeat until the covering
is tight with no wrinkles.
If wrinkles keep coming back on the tail surfaces, you may need
to “ventilate” the areas between the ribs. Otherwise the air that is
sealed in those relatively small areas will expand when the heat
is applied and actually cause the covering to stretch instead of
shrink. Use a pin to poke a tiny hole in the covering between each
rib, on the bottom of the part. That will let the expanding air es-
cape and the covering to shrink properly.
Caution When Using Heat Guns: You can also use a hobby-type
heat gun to shrink the covering, but you must be careful around
seams or color joints. Getting too much heat on the seams may
cause them to "creep" or come loose. You must also be careful
when using a heat gun when working around the windshield and
side windows - heat will distort the clear plastic material.

NOTE:
In this manual, any references to right or left, refer to your
right or left as if you were seated in the cockpit of the airplane.
The wings are designed as a 2-piece system, with separate right
and left wing panels joined by an aluminum tube wing joiner and
a hardwood locating pin at the rear. Due to the high strength of
the wing joiner tube, the wing panels do not need to be perma-
nently glued together. Gluing them permanently together is op-
tional - your call. The obvious benefit to leaving the wing panels
separate is the fact that they can be easily transported or stored.
To help protect your wings during the following steps we recom-
mend that you cover your work surface with a soft cloth or piece
of soft cell foam.
INSTALLING THE AILERON SERVOS
For the following steps you will need:
(1) Right Wing Panel
(1) Left Wing Panel
(1) Aluminum Tube Wing Joiner
(2) Servos with Mounting Screws (not furnished)
(2) 12” Servo Extension Chords (not furnished)
(1) Servo Y- Harness (not furnished)
❑
1) Mount the aileron servos in the bottom of each wing panel.
a) The servo bays are precut for you but you’ll want to double
check the covering around the cutout to make sure it is sealed
down tight.
b) Install the rubber grommets and brass eyelets (supplied with
your radio system) into each aileron servo.
c) Install the control arms on the two aileron servos. The arms
should be at 90 degrees to the servo when the aileron control stick
on the transmitter is in neutral and the transmitter trims are in neu-
tral as well.
d) Before installing the aileron servos in the wing panels you
must attach a servo extension chord to the aileron servo wire. The
typical combined length required is approximately 24”. A 12” ex-
tension chord will usually provide sufficient length. Plug the servo
plug into the extension chord and tape the plugs together for
added security.
e) A string is provided in the wing panel for pulling the aileron
servo chord through the wing. Each end of the string is taped on
the outside of the wing panel. Carefully untape the string at the
servo opening and tie the end of the string securely to the end of
the servo wire, as shown.
f) Untape the string at the root end of the wing panel and begin
carefully pulling the string and the aileron chord through the wing
You will occasionally feel like the wire has become stuck inside
the wing. This is simply the plug on the end of the servo wire hit-
ting the side of one of the holes in the wing ribs. Gently work the
string back and forth from both ends until the plug slips through
the hole. Sometimes the servo plug comes through all the ribs
the first time without getting hung up, and other times it seem like
it gets hung up on every rib. Be patient and don’t try to force it.
