INSTALLING THE PLUG-IN WING
To install the plug-in wing to the fuselage you will need the
following parts.
- 2 aluminum tube spar joiners 2/3 inch (16mm) diameter
- 2 aluminum collars (see wing roots)
- 2 steel butterfly nuts (4mm) (see wing roots)
Step 1. Remove the hatch cover from
the bottom of the fuselage by
removing the retaining screws
and sliding the hatch slightly aft.
Step 2. Insert the front wing spar
joiner and then the rear spar joiner (see picture 1.2 & 1.3)
Step 3. Remove the nut and aluminum collar from the wing root
stud bolts. (see picture 1.4)
Step 4. Carefully insert the 2 wing
spar joiner tubes into the left
wing. (see picture 1.5)
Step 5.
Carefully mount the right
wing on to the spar joiner tubes.
(see picture 1.6)
Step 6. Secure the wings with
the collars & butterfly nuts.

To install the aileron servos into the wing you will need the
following items :
- Servo
- Servo 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 on to one end .
- Low tack masking tape.
- 2 aileron control horn assemblies
2.1 Prepare the servos by fitting the rubber
grommets & ferrules supplied with your radio
FITTING AILERON SERVOS
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. Remove the white cover
plates and retain the mounting screws. Notice that there are
wooden servo rails pre-installed into each servo cavity end.
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.
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
Install the aileron control horns.

Step 1 Consult your radio instruction manual and center each aileron servo by plugging it into the aileron chan-
nel 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.
Step 2 Mount the servo arm back on the servo. Position the arm so that the arm is perpendicular to the surface of
the wing. Screw the arm into place with the servo arm mounting screw supplied with the servo.
Locate the two aileron control rods in the hardware bag. Ensure the clevise is well screwed on to the threaded
portion of the rod. Rotate and tug aggressively on the clevis and ensure that they are not loose on the rods.
Tape the ailerons into their neutral position so that they are even with the trailing edge of the wing and not pointing
either up or down.
Step 3 Ensure that the aileron control horns are screwed on to the threaded aileron control horn bolts and that both
control horns are in approximately the same place on their respective bolts.

Step 4 Connect the clevis on each rod to their respective servo ouput arm.
metal pin or screw, attach that clevis to the servo output arm.
Step 5 Connect the other end of each aileron servo rod to the aileron control horn using the EZ connector.
Step 6 Remove the masking tape holding the ailerons.
Step 7 In the case of computer radios, couple 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.
Step 8 Turn on your radio and activate the ailerons, using the aileron stick and ensure that a smooth full motion
can be achieved.
Step 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 ).
Step 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.

FITTING FLAP SERVOS
To install the flap servos into the wings you will need
the following items :
- Servos
- Servo mounting screws and grommets as supplied
with the servo.
- Servo control arm as supplied with the servo.
- Flap control rod assemblies
- Low tack masking tape.

FITTING THE HORIZONTAL AND VERTICAL STABILIZER
To install the stabilizers to the fuselage you will need.
- Fuselage
- Vertical stabilizer with pre-installed rudder
- Horizontal stabilizer with pre-installed elevator
5.2 Factory machined stablizer slots.

Check the fit of the horizontal stabilizer
in its slot. Make sure the tail is square
and centred to the fuselage by taking
measurements as shown in the diagrams on the right, but don’t glue anything yet.
