STAGE 1 – WING ASSEMBLY.

JOINING THE WING HALVES

1.1Locate 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. Mark the joiner to indicate which way is UP as illustrated in 1A.

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 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 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 top of the wing, pressing

down firmly as you go.

3A- Apply tape over the joint,

starting here

4B- Aileron servo location

4A- Prepare the servos by fitting the rubber

grommets & ferrules supplied with your radio

STAGE 4 - INSTALLING THE AILERON SERVO

INTO THE WING.

4.1 Turn the wing upside down.

4.2 Trial fit the aileron servo into the center of the servo mout-

ing cavity. You may have to modify the cavity slightly to pro-

vide clearance for the servo and servo wires.

4.3 Use a hobby knife to modify the cavity as required. Most

servos have their output shaft closer to one end than the

other. We recommend locating the servo so that the output

shaft is as close to the front of the wing as possible.

4.4 Screw the servo into place with the screws and grommets

supplied. It is important to install the grommets and screws

correctly. See the manual that came with your radio for

instructions about your particular servo grommets.

4.5 Fasten the screws down according to the manufacturers

recommended tightness.

To install the aileron servo into the wing you will need the fol-

lowing items :

- Servo

- 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 a plastic clevis

screwed onto both ends.

- Low tack masking tape.

- 2 aileron control horn assemblies

STAGE 5 - INSTALLING AILERON CONTROL SYSTEM

5A- Aileron control rod assembly 5B- Aileron torque rod with con-

trol horn

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.

5.4 Tape the ailerons into their neutral position so that they are even with the trailing edge of the wing and not point-

ing either up or down.

5.5 Ensure that the aileron control horns are screwed onto the threaded aileron torque rods that protrude from the

wing and that both control horns are in approximately the same place on their respective torque rods (see 5B).

Aileron Aileron

5.6 Connect the aileron servo control rods to the aileron control horns as shown in 5C.

5.7 Carefully remove the masking tape holding the ailerons.

5.8 Turn on your radio and activate the ailerons, using the aileron stick and ensure that a smooth full motion can

be achieved.

5.9 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).

5.10 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).

Engines vary quite a bit in sizes, styles and brands but

most have mounting lugs, a carburetor with a throttle

(speed) control arm, a prop washer, a prop nut and a

muffler.

The procedure we describe here assumes that you are

mounting a 2-stroke engine that has a side exhaust on

the right (when viewed from behind looking forward)

and a throttle control arm on the right.

To assemble the fuel tank you will need the following

items:

- The fuel tank and fuel stopper assembly (supplied)

- The clunk (supplied)

27.1 Adjust the deflection of the control surfaces to match the specifications on page 15

You can reduce the amount of throw by doing either or both of the following:

- From the servo end, move the clevis or EZ connector to a hole in the servo arm that is closer to the servo output

shaft.

- From the control horn end, move the horn out further on the threaded bolts. Always confirm that the horn is still

thoroughly engaged with the threaded bolt after you have adjusted it.

Before starting the final

set-up of the model,

switch on the radio and

ensure that all trims are

in their neutral posi-

tions. Check that the

ailerons, elevator and

rudder are centered. If

any adjustments are

needed, do these by

uncoupling the relevant

clevis and turning it

clockwise to shorten

the linkage or counter -

clockwise to lengthen it.

Only when each control

surface has been cen-

tered mechanically in

this way should you

begin adjusting the sur-

face movement (or

throw)

Now confirm

that the con-

trol surfaces

are moving

in the correct

direction.

Use the

servo revers-

ing switches

on your

transmitter to

reverse the

direction of a

servo if nec-

essary. The
