WING ASSEMBLY - JOINING THE WING HALVES

Step 1.1 Locate the wing joiner (also called Dihedral

brace). Using a ruler, determine the center of the wing join­er and mark it with a pencil as illustrated in 1A. Also mark
a center line on each of the dowel guides.

Step 1.2 Trial fit the wing joiner into the wing panels. It
should insert smoothly up to the center line as illustrated in
1B. Now slide the other wing panel onto the wing joiner until
the wing panels meet. If the fit is overly tight, sand the wing
joiner slightly and try again. Mark the joiner to indicate
which way is UP as illustrated in 1A.

1A - Preparation of wing joiner and dowel guides. 1B - Trial fit the wing joiner and dowel guides

34A - Using a ruler and pen, measure and mark the loca­tion where the ailerons will be cut. Measure carefully

35A - Use a hack saw blade or a hobby razor saw to cut
through the ailerons at the locations marked

Step 1.3 Insert the dowel guides into one of the wing pan-

els all the way to the center lines. Apply CAglue to secure
the dowels into their places as illustrated in 1B and 1C. Do
not apply CA glue to the wing joiner.

The Xtreme Stick 40 is designed with 0 degree dihedral

( i.e. the Wing is designed with no bend at the center)

Step 1.4 Apply plenty of 30 minute epoxy to one end of the

wing joiner, using a stir stick or epoxy brush. Carefully
insert the joiner into the first wing panel as illustrated in 1D,
1E and 1F, then wipe off the excess epoxy that squeezes
out of the joint with a cloth or tissue. Repeat this process
several times to ensure that the wing joiner and cavity are
well coated in epoxy. When the wing joiner & cavity are well
coated with 30 minute epoxy, insert the joiner to the center
line, wipe away any excess epoxy and let dry. (Note: Do not
use 5 minute epoxy or CA to join the wings)

1C - Apply CA glue to secure dowels into their places 1D - Apply plenty of 30 minute epoxy to the wing joiner.

CONTROL SURFACE THROW SPECIFICATIONS:
The throws are measured at the widest part of the control
surface. Adjust the position of the pushrods at the control
and/or servo horns to control the amount of throw. You may

also use ATV's if your radio has them but the mechanical
linkages should still be set so that the ATV's are near 100%
for best servo resolution.

The quad flap option and a computer radio allows your
Xtreme Stick 40 to perform complex flight maneuvers that
are just not possible using ailerons only.
With quad flaps and a computer radio different wing con-

figurations can be programmed to extend the flight per­formance envelope.
The procedures for activating the quad flap option are sum­marized below.

Step 34.1 Once you have cut the ailerons as illustrated in
34A & 34B, install the two flap servos into the wing, install
the flap control horns and install the flap control horns. See
Stages 4 - 6 as an example of the general procedure.

Step 34.2 After installing and connecting the servo control
rods, review your computer radio manual for details on con­necting the flap servos to your receiver & on how to config­ure your computer radio to control flaps & ailerons in a
coordinated manner

STAGE 34

Step 32.1 The CG for your Xtreme Stick is located at 3­1/8“ to 3-1/2" (80 - 90 mm) back from the leading edge of
the wing when the wing has been attached to the fuselage
as per illustration 33A.
Step 32.2 For the initial flight, the CG should be located at
3 1/8” (80mm) back from the leading edge of the wing when
the wing has been attached to the fuselage.
Step 32.3 The CG is measured with the engine, radio gear
and all other components installed but WITH NO FUEL IN
THE TANK.
Step 32.4 Set up the CG as it will be when you fly it BUT
WITH NO FUEL IN THE TANK.
Step 32.5 It is very important to have the CG correct.
Flying your model with the CG too far back will likely lead

to loss of control and a crash. If you discover that after you
have assembled your model and installed your radio and
engine that the CG of your model is incorrect you must
bring the CG to the correct location by doing the following
BEFORE FLYING :

- Move the battery pack fore or aft.

- Move other components fore or aft.

- Change engine to a lighter or heavier model.

- Add weight to the nose or tail. If adding weight to the
nose, try to make it useful by going to a heavier duty engine
or adding a spinner with a heavy metal backing plate. As a
last resort, add stick on “dead” weight where appropriate.

Step 2.1 When the epoxy has cured in Stage 1, trial fit the
second wing panel onto the wing joiner first to ensure that
the two panels fit without an excessive gap.

Step 2.2 Now apply plenty of epoxy to the wing joiner and
wing root ribs of both wing panels. Use only 30 minute
epoxy to ensure a strong bond and give yourself plenty of
working time. As described in the Step 1.4, repeatedly

apply epoxy and insert into the wing joiner cavity, the epoxy
should ooze from the joint and the excess should be
cleaned off with a rag or tissue before it cures.

Step 2.3 Use low tack masking tape to hold the two wing
panels together until the epoxy cures. See 2C

1E - Carefully insert the joiner all the way to the center line

Step 3.1 Once the epoxy has cured completely (allow sev-

eral hours at least), the tape can be carefully removed from
the wing panels. Peel the tape back on itself… do not pull
upright away from the wing. To seal and finish the joint in
the wings, a roll of wing joiner tape has been supplied.
Starting on the bottom side of the wing, stick the tape cen-

trally over the joint ensuring that it is pressed down firmly
as you work around the wing. Wrap the tape all the way
around the wing joint in one piece, starting and finishing at
the servo mounting cavity in the bottom of the wing.

STAGE 33

Step 30.1 Consult your radio manual for instructions about

hooking up your receiver.
Step 30.2 Plan where you are going to put the receiver
with consideration for routing the antenna safely.
Step 30.3 Wrap the receiver securely in foam suitable for
RC equipment and wrap the foam insulated receiver in a
plastic bag or cling wrap.

Step 30.4 Generally in the absence of specific instructions
from the radio manufacturer, it is recommended that the
receiver should be placed where it is least likely to have
impact during a crash. Keep the battery pack and other
heavy loose items ahead of the receiver.

Step 31.1 Consult your radio manual for instructions about
testing and operating your radio system.
Step 31.2 Pay particular attention to charging your radio
system batteries and range testing the system before and
after each flight.

Step 31.3 Check that all controls are working correctly
before and after each flight.

Step 33.1 Once you have confirmed that the
CG is correct, you should do a thorough review
of the entire model before your first flight.
Check everything twice! Every hook up, every
coupling, everything! Do it twice!!
Step 33.2 Before your first flight, have an
experienced flyer review your work. Do not fly
your model until it has been checked out by a
third party who knows how to fly and how to
set up a model aircraft. Do not fly alone. Seek
experienced help.
Step 33.3 Once you have completed your first
flight, get in the habit of checking your model over
before and after each flight! Don’t fly if you find
something that is not right!
