11- JOINING THE WING

Without using Epoxy yet, trial fit the wing joiner into one

of the wing panels.

Next, slide the other wing half onto the dihedral brace until the

wing panels meet. If the fit is overly tight, it may be necessary to lightly

sand the dihedral brace.

Epoxy

Carefully slide the wing halves together, ensuring that

they are accurately aligned.

Firmly press the two halves together, allowing the excess epoxy

to run out. Using a paper towel, clean off the excess epoxy.

NOTE:

Please do not clean off the excess epoxy on the wing with strong solvent or pure alcohol

to keep the colour of your model not fade.

13- HORIZONTAL STABILIZER

13A

Cut away only

the covering

Using a sharp hobby knife, carefully cut away the covering

around of all slots for the horizontal stabilizer and vertical

fin installation.

Remove the left and right elevator out of the horizontal stabilizer.

Push the horizontal stabilizer into the slot on the fuselage

as show. Check the alignment of the horizontal stabilizer

by measuring from a fixed point along the center line of

the fuselage to the leading edge on each side of the

horizontal stabilizer. The distance must be equal on both

sides . If not, adjust the stabilizer until the measurements

are the same (see picture below: A=A’).

A = A’

When you are satisfied with the alignment, use

a pencil to trace around the top and bottom of

the stabilizer where it meets the fuselage (13B).

13B

A’

Remove the horizontal stabilizer

from the fuselage. Using a straight edge

and a sharp hobby knife, carefully cut away

the covering inside the lines which were marked

above. Be cautious not to cut into the wood-this

will weaken the structure (13C).

Cut away only

the covering

both side

13C

Page 13

14- HORIZONTAL STABILIZER & VERTICAL STABILIZER

Apply thin CA glue into the slot where

the fuselage meet the horizontal stabilizer.

14A

Install the horizontal stabilizer onto the fuselage and adjust the alignment as

described in steep 13A.

Note: it is important to ensure that the horizontal stabilizer is also level in regards to the

fuselage.

Apply the thin CA along the area where the covering was removed in the previous step and to the

fuselage where the horizontal stabilizer mounts .

! Securely glue together. If coming off during fly,

you lose control of your air plane.

Carefully, push the vertical fin into the

slot on the fuselage as shown (14B).

Pull the rudder out of the vertical fin.

Apply CA glue

both sides.

14C

Trial fit the vertical fin in position. Using

a 90 degree triangle, ensure that the

vertical stabilizer is perpendicular to the

horizontal stabilizer (14C).

Using a pencil, trace around the vertical

stabilizer where it meets the fuselage.

Remove the vertical stabilizer from the

fuselage.

Page 14

15- VERTICAL STABILIZER

Remove the vertical stabilizer from the fuselage.

Using s sharp hobby knife, carefully cut away the

covering below the lines which were drawn in the

previous steep. Do not cut into the woods as this

will affect the structural integrity of the stabilizer (15A).

Insert the vertical fin into the fuselage, precisely align the vertical stabilizer

as described in step 14C.

Apply the thin CA glue on the vertical stabilizer where it contacts the fuselage.

! Securely glue together. If coming off during fly, you lose control of your

air plane.

Note: Cut out the stickers and apply them in the proper area. Do not

peel the backing paper off all at once.

Peel off one corner of the backing and cut off with scissors.

Arrange sticker on model and when satisfied adhere the corner without

backing.

Carefully peel back the rest of the backing while at the same time

adhering the rest of the sticker.

Try not to make air bubbles, if there are some, carefully puncture sticker

(center of bubble) but not model surface with

the tip of the knife or sharp pin and squeeze out the air.

At curves stretch sticker and apply a little heat so that no ceases occur.

Cut off the excess that is produced.
