Step 31 - Wing Assembly (lower WS sheeting)
Locate two WS pieces from BP13. These pieces are glued together
to form a single piece of lower center sheeting.
Using the same techniques you used to cut and install the upper
WS sheets, trim, glue and install these WS piece to form the lower
center sheeting.
Step 32 - Wing Assembly (bottom cap strips)
Measure, cut and glue strips of 1/16" x 2" x 24" sheeting for the
bottom cap-strips.
Use the same techniques as you used when applying the top cap
strips earlier in the build.
Step 33 - Wing Assembly (trim strip)
You should have spare lengths
of 5/16” or 1/4" square balsa,
trimmed from the leading
edge.
Use these pieces to make a
strip that will be glued to the
basswood mounts for the
aileron hatches. They should
run the width between the cap
strips and be flush with the
outer surface of the cap strips - as shown here.
These is not a structural pieces. Instead they are trim pieces that
aid in covering later on, as you’ll have to cut out the covering in this
area to install the servo and hatch.
Step 34 - Wing Assembly (R7)
Locate one R7 rib from BP9/
BP10. This are glued to the face
of R6 as shown, to double up the
piece.
Take care not to get any excess
glue into the rectangular pre-cut
slots of R6 and R7, as they need
to be open for the next step.
Step 35 - Wing Assembly (T1-T5)
Locate one set of T1 - T5 tip supports from BP1. Pay attention to
the order they are installed (T1
nearest the leading edge, back
to T5 closest to the the trailing
edge.)
When properly installed, the
notch on each piece should go
through both the R7 and R6 ribs.
Glue these in place.
Step 36 - Wing Assembly (T6, T7, and T8)
Locate one T6 & T7 from BP12
and one T8 from BP13. These
are all used to form the upper
tip sheeting.
Using the same technique to
join sheeting as you did to
join the WS pieces together
in step 20, glue T6 to T7, then
T7 to T8.
Note that the grain of T6 and T7 will be with the length of the wing,
while T8 will be against it. This allows T6 and T7 to easily bend to
over the leading edge.
Test fit first, then when satisfied with the fit, glue this sheeting in
position, making sure it is firmly glued to each tip support, the top
of R7 as well as the leading and trailing edge pieces.
Step 37 - Wing Assembly (trim trailing edge)
Refer to this photo to aid in
trimming the trailing edge piece.
It needs to be angled as we've
shown here so it will allow the
sheeting (installed in the next
step) to be correctly installed.
Step 38 - Wing Assembly (lower tip sheeting)
Using
scrap
1/16th
sheeting
(NOT sheeting
from the other 1/16" x
4" x 24" sheets)
, cut a few
pieces to form a length that
will run from T1 back to the
trailing edge. We suggest
you cut the pieces slightly
oversized just in case they
are slightly mis-aligned.
(You can easily remove the extra when sanding.)
Note the grain will run with the length of the wing as shown here.
Test fit first, then when satisfied with the fit, glue this sheeting in
position, making sure it is firmly glued to each tip support, R7 as
well as the leading and trailing edge pieces as it twists from front
to rear.
Step 39 - Wing Assembly (T9)
Locate four T9 pieces from
BP14. These are stacked in the
empty space between T1 and
the leading edge.
Note that the pieces used in the
photo might look a bit sloppy
compared to your pieces. These
were hand-cut from scrap for the
prototype - your's are laser-cut.
Glue these in place as shown. You'll need to slightly notch the rear
edge of the leading edge strip to allow the the front T9 to slot into
place.
Wing Assembly (port wing)
Set the starboard wing half aside and begin work on the port (right)
wing half. Tape the port wing plan and fresh wax paper on your
board. Then go back and follow steps 2 through 39 to assemble
the port wing half. Once finished, then move on to step 40 to
complete the wing assembly.
Note that when building the port half, some of the parts will need
to be glued to the opposite side (sheer webs, etc.). Always refer
to the plans to make sure you’re gluing the parts together in the
correct way.
