Step 39 - Wing - (T1 - optional)
Locate T1 from LP2. This is an optional
piece - just for looks (and it might add
a little stability, but more for looks if I'm
honest). And while I'm being honest, it's
even optional whether or not you install
them at this point.
I found it easier to install it now, rather than later. If you're going to
do it, note its orientation first - the thinner "bullet-shaped" part is
the front, leaving the taller, tapered edge to be the rear. Also, we
found they look best when pointed upwards, but they could be
flipped to point down if you'd like - your choice.
Regardless of the orientation you choose, T1 should be roughly
centered on the wing's tip. Test fit it into place first, then make a
few pencil marks to help align it. Now glue this in place making
sure it's aligned to the marks you made.

Step 40 - Wing (R1)
Now it's time to cut a square
hole out of the root rib (R1).
This will be between the pre-
cut slots for the sheer webs
and between the upper and
lower spars, as shown here. Carefully using a rotary tool to do most
of the work is best, then clean up everything with a hobby knife. Do
not cut into the sheer webs as you will weaken them.

Step 41 - Wing (aileron hatch cutout)
In the back of this manual is Appendix
B which is a full-size template that
you should use to locate and cut out
the aileron pockets.
Remove that page, cutout the
template and place it as shown here,
on the bottom of the starboard wing
panel.
The rectangular cutout is pretty close
to the size, but I advise lightly cutting
inside it by 1/8" or so - using just enough
pressure to cut through the outer
sheeting. You should now have a hole
that reveals the hatch rails, similar to
what's shown here (except hopefully a bit
neater than my example).
An easy way to find the sides of the box
is to take a piece of scrap 3/16" x 3/8"
and place it directly over one of the servo
rails, mark, then cut this outer edge. Do
the same to find the outer edge of the
other rail.
Then carefully cut away the fore and aft edges of the box so the
sheeting is flush with the lower spar and the rear frame of the aileron
box.
Test fit one of the servo hatches (SH, from LP2). Lightly sand the
opening to allow the hatch to comfortably fit in the opening.

Step 42 - Wing (sanding)
Grab your sanding block and sand the inside (root) face of R1 and
the trailing edge piece you installed so it's all flat and smooth.

Set the starboard wing half aside and begin work on the port
wing half. Tape the port wing plan and fresh wax paper on
your board. Then follow steps 12 through 42 to complete the
port wing half. Once finished, then move on to step 43.
Note that when building the port half that many of the parts
will need to be glued to the opposite side (the sheer webs, for
instance). Always refer to the plans to make sure you're gluing
n
Step 43 - Center section (FS7, FS9)
Locate both FS9s from LP2 and both FS7s from BP6. Before any
glue makes it out of the bottle, do a test run. The result is that you'll
need two sub-assemblies, mirror images of each other, and perfectly
aligned along the top, front and rear edges - but NOT the bottom.
Also, FS7 has a temporary spacer that will need to be cutout before
it's glued in place.
Once, and only once you're sure
on how these pieces should go
together, glue them in place.
They should
aligned, mirror images and flat
along their entire lengths - just
as in this picture.
n
Step 44 - Center section (1/4" strips)
Locate one of the 1/4" x 36" strips of balsa. Then flip the FS7/9
assemblies over. Note the lip on the bottom of each piece - where
the ply is 1/4" short of the balsa sheeting. Thats where this 1/4"
strip will go.
You'll cut two pieces for each sheet. One that runs from the front
edge to the landing gear support
cutout. The other from the rear edge
to the landing gear support cutout.
Glue these pieces in place up-against
the lite-ply and note that you'll have to
use a little force to make them curve
to match the shape of the sheeting..
n
Step 45 - Center section, (TR3)
Locate TR3 from LP5.
Now orientation is key here -
please pay attention!!!!!
Place the STARBOARD side on the
plans as shown, then glue TR3 in
place, noting where the u-shaped
and circle cutouts should be.
Please refer to his picture.
TR3 should be perpendicular to the
starboard side and you can use the 90° angle we referenced earlier.
n
Step 46 - Center section (F6A)
Locate F6A from LP4. This is glued to the rear
of the starboard side, with it's tabs fully inserted
into the cutouts in the side sheeting and TR3
you just installed.
