STAGE 1

– WING ASSEMBLY.

JOINING THE WING HALVES

1.1 Locate the wing joiner (also called Dihedral brace). Using the 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.

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

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)

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.

1.3 Insert the dowel guides into one of the wing panels all the way to the center lines. Apply CA glue to secure the

dowels into their places as illustrated in 1B and 1C. Do not apply CA glue to the wing joiner.

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

joiner.

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.

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.

2.3 Use low tack masking tape to hold the two panels together until
the glue cures.

1E- Carefully insert the joiner all the way to the cen-

ter line

2A- Apply plenty of 30 minute epoxy
glue to all surfaces.

2C- Use low tack masking tape to hold tightly

together.

3.1 Once the epoxy has cured completely (allow several 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 cen­trally 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 wiring harness cavities at the bottom of the wing.

Center line pointing up

1F - Wipe off the excess epoxy then allow to cure.

2B- Align the two wing panels and slowly close the

gap until the wing root ends are firmly in contact

with each other

3C- Trim off the excess tape.

3B- Continue applying the tape

over the bottom of the wing,

pressing down firmly as you go.

3A- Apply tape over the joint,

starting here

STAGE 4

- INSTALLING THE AILERON SERVO INTO THE WING.

To install the aileron servo into the wing you will need the fol­lowing items :

- 2 servos

- Servos mounting screws and grommets as supplied with ser­vos.

- Servo control arms as supplied with the servos.

- Two aileron control rod assemblies supplied with the kit. The
assemblies consist of a metal rod with clevis screwed onto both
ends.

- Low tack masking tape.

- 2 aileron control horn assemblies

- 1 servo wire connection wire

STAGE 5 - INSTALLING AILERON CONTROL SYSTEM

5A- Aileron control rod assembly 5B- Aileron control horn assembly 5C- Aileron control installed

5.1 Consult your radio instruction manual and center the aileron servo by plugging it into the aileron channel in the

receiver. Turn on the transmitter and then the receiver. Center the aileron trim lever on the transmitter. Remove the
servo arm mounting screw and the servo arm.

5.2 Mount the servo arm back on the servo so that the arm is parallel with the back edge of the wing. Screw the
arm into place with the servo arm mounting screw supplied with the servo.

5.3 Locate the two aileron control rods in the hardware bag (see 5A). Ensure the clevises are screwed well onto
the threaded portion of the rod. Rotate and tug aggressively on the clevises and ensure that they are not loose on
the rods.

5.5 Ensure that the aileron control horns are screwed onto the threaded aileron control horn bolts and that both
control horns are in approximately the same place on their respective bolts.

4.1 Carefully remove the white cover plates from the aileron

servo cavities. Ensure you know which cover plate is for the
right wing and which is for the left. Notice that there are wood­en servo rails pre-installed into each servo cavity end.

4.2 Locate the wiring harness tubes that are protruding slightly
into each aileron servo cavity. The tube can be moved slightly
at this point. Check out the other end of each tube for a clean
position and then using C/A glue secure the wiring harness
tubes at the aileron servo cavity end.

4.3 Install a servo in each aileron servo cavity and connect the
servo wire to the servo extension wires and run the extension
wires through wiring harness tubes to the centre of the wing

STAGE 7 - ALIGNMENT OF HORIZONTAL STABILIZER

7.1 Check the fit of the horizontal stabilizer in its slot. Make sure the

tail is square and centered to the fuselage by taking measurements
as shown in pictures 7A, 7B and 7C. Do not glue anything yet.

5.6 Connect the aileron servo rods to the aileron control horns.The one end with clevis will be attached to the servo

output arm.

5.7 Connect the other end of the rod to the control horn pre-installed with an EZ connector

5.8 Remove the masking tape holding the ailerons.

In the case of computer radios the servos together by connecting them to the appropriate receiver channel. In the
case of analog radios couple the servos together using a Y harness

5.10 Turn on your radio and activate the ailerons, using the aileron stick and ensure a smooth full motion can be
achieved.

5.11 With the wing top side up and viewed from the back, ensure that moving the transmitter aileron stick to the left
raises the left aileron and lowers the right aileron. Movement of the stick to the left will roll the aircraft to the left.
(Counterclockwise roll of the wing when viewed from the back ).

5.12 With the wing top side up and viewed from the back, ensure that moving the transmitter aileron stick to the
right raises the right aileron and lowers the left aileron. Movement of the stick to the right will roll the aircraft to the
right. (Clockwise roll of the wing when viewed from the back).
