Following are the before and
after photos to help show what
needs to be done.
Now, before cutting this area
away, make sure that the SW1
and SW2's are securely glued to
the R3 ribs on the outside of this
area - not the inside. This way
things won't move as you cut.
After cutting, make sure that the
area is completely clean and smooth, as this will form 3 sides of
a box where the dihedral brace will slide through. The cleaner/
smoother it is now, the easier it will be to slide in the brace when
it’s time.
Take your time and use a gentle touch in this step as you don’t
want to cut/sand/file more than you should, nor do you want to
damage the sheer webs in these spots as it could weaken the wing
or cause a misalignment.
Note that a Japanese saw is the perfect tool for this job.

Step 22 - Wing Assembly (top spar)
Locate another length of 1/8" x
1/4" x 36” basswood strip to use
as the upper spar. Measure and
trim it to length, again, leaving
about a 1/4” extra past the root
rib (R3). On the wing tip side, you'll
need to sand an shallow angle into
the piece to obtain a nice, tapered
look when attaching it to the top of
the wing tip sheeting as shown here.
To install this piece, first lightly sand the
edges of the bottom face of the spar as
shown in the drawing to the right. This will
help the spar slide in easier.
Gluing this in the piece this correctly will
take a bit of time, so we recommend
against using an instant setting glue. If you are using CA, use a
thicker formulation that gives you a bit of working time.
Attach the spar to the wing tip first. Once that glue has cured, or
you have secured it with pins, weights, etc., you can work you way
down the rib, a little at a time pressing the upper spar into position.
This will be a tight fit and might require “wiggling” the spar from
side to side to slip in-between the webs. Be sure to press the spar
completely into the slot in each rib, making it flush with the webs.
Once the spar is in place, wick thin C/A along the spar to web joints
(front and back) along the entire length of the spar.
When fitting the upper spar in the area of the dihedral box, be
careful not to drip excess glue into the box formed between R3 ribs.

Step 23 - Wing Assembly (Ailerons only - S1, S3)
If there's no ailerons in your
future, skip this step.
For those of who like ailerons,
it's time to build up the frame
around the aileron servo's
hatch.
Locate one SH1, and one SH3
from LP4 or LP7.
Place (DO NOT GLUE) SH1 in
place on the plans, between the ribs and up against the lower spar.
Now SW3 will be installed to form the 4th side of the aileron box. It
should be snug up against both ribs, and loosely against SH1. I say
loosely because you'll want to leave a touch of room to account for
the thickness of covering to be applied later.
When satisfied with the fit, glue SW3 in place to the ribs - NOT
SW1.

Step 24 - Wing Assembly (Ailerons only - S2)
Here's another one of those
aileron-only steps, so skip ahead
of you're aileron-phobic.
Locate four SH2s, from LP4 or LP7.
Two SH2s are glued on top of each
other, to form a pair of thicker
SH2s.
With the SW1 in place from the
last step, you'll now set these on
top of SW1, up against the ribs and against the web - refer to this
photo.
When satisfied with how these are installed, carefully glue them in
place to the ribs, the web and where it touches SW3.
But DO NOT GLUE THEM TO SW1.

Step 25 - Wing Assembly (Ailerons only - A1)
Now it's time to build up the
aileron. So if you're into three
channels, then sit this one out.
Locate A1 from BP5. To be
used as an aileron, it is slightly
longer than it needs to be.
Sand/trim this piece to it fits
in the aileron area with about
1/16" inch clearance on each
side of the R6 ribs. Pin this in position.
n n
Step 26 - Wing Assembly (Ailerons only - A2)
Locate four of the A2s from
BP1, BP2 or BP3. These
are glued in place to form
the "ribs" of the aileron.
You'll glue two of them
to the outer edges of the
A1 sheeting, parallel with
the ribs. The the other two
should be lined up with the
ribs already in place on the main wing (extending the look).
Don't worry about the other two marked on the plans just yet.

Step 27 - Wing Assembly (Ailerons only - L.E.)
Locate one of the 3/16" sq. x
36" balsa strips. This will be used
to make the leading edge and
CA hinge supports.
Measure and cut a length to
form the leading edge, leaving
touch over.
Glue this in place.
