Now, glue R5 in place. When it is properly aligned, the SW1 tabs
will be fully seated and R5 will be at a 90° angle to the building
surface. Also tack the rear tab to the waxed paper.
Step 15 - Wing Assembly (R6 and R7)
Locate two R6s and two R7s from
BP2 as well as both SW2s and
SW3s from BP10.
Starting with SW2, test fit then
glue in position, followed by R6,
then SW3 and finally R7.
Also tack the rear tabs on R6 and
R7 to the waxed paper.
You are remembering to build both sides of the wing
at the same time, aren’t you?
Step 16 - Wing Assembly (aileron servo rails)
Locate the leftover 3/16” x 3/8”
basswood strips you cut when
creating the upper spar in step 3.
Measure and cut two lengths to
span the width between the R6
and R7 ribs, leaving an extra 1/8”
or so on each side.
Slide these pieces into the pre-cut
slots in the ribs, forming the servo rails. Glue these in position.
Step 17 - Wing Assembly (R8 & R9)
Locate two R8s and two R9s from BP1
as well as both SW4s and SW5s from
BP10.
Starting with SW4, test fit then glue
in position, followed by R8, then SW5
and finally R9.
Also tack the rear tabs on R8 and R9 to
the waxed paper.
Step 18 - Wing Assembly (R10/wingtip)
Locate both R10s, TP3s
and TP5s from BP1. Also
locate both TP1s, both
TP2s and both TP4s from
BP2.
Glue one TP1 to TP2 as
shown. Make two TP1/
TP2 assemblies.
Build two R10 assemblies
by gluing TP3, TP4, and
TP5 into their respective notches in R10. Make sure each of these
pieces are glued in at a 90° angle to the R10, and pay attention to
the orientation of these pieces as it is possible to insert them the
wrong way. The small etched circles are to be oriented to the top
of the wing (the edge with the tab on it).
When making the other R10 assembly, remember that it needs to
be a mirror image of the first one (a port and a starboard wingtip).
They are not interchangeable.
To finish the R10/wingtips, slide the TP1/TP2 assembly into the
slots in the TP3-5 pieces. When the TP1/TP2 is properly positioned,
it’s front tab will be completely inserted into the pre-cut slot in R10,
and it will be in contact with the rear of R10, as shown. Glue in
position.
Step 19 - Wing Assembly (R10/wingtips)
Locate both SW6s from BP10.
Test fit, then glue these in
position.
Now locate the wingtips you
created in the previous step.
These are glued in position. Pay
careful attention to which tip is
going where, as to not mix them
up.
Also remember to tack to down the rear tab to the waxed paper.
Step 20 - Wing Assembly (trailing edge)
Locate both leftover 1/4” x 1/2”
balsa sticks you trimmed earlier.
Measure and cut these to fit in
the rear groove pre-cut into the
ribs. Make sure these pieces are
fully inserted, and when properly
in position, glue in place.
Now locate two 1/8” x 1/4” x
36” balsa strips. Measure and cut these to glue to the top surface
of both trailing edge pieces you just installed. As these trailing
edges are set further into the wing, they need to be a touch higher
and the added 1/8” of thickness does the trick.
DO NOT ADD THIS FOR THE CENTER SECTION INSTALLED
EARLIER IN THE BUILD.
Step 21 - Wing Assembly (lower spar)
Locate two more of the 3/16” x 3/8” x 36” basswood strips. These
will form the lower spar. Position
over the plan, measure to length
and cut.
When gluing these two pieces in
place, make sure you work from
the center of the wing, out - one
strip at a time. Also make sure
to get plenty of glue for a good
bond to DH1, as well as all of
the ribs. These strips will need to bend slightly around R4, so make
sure to keep pressure (or weight) on them until the glue has cured.
Step 22 - Wing Assembly (lower sub-spar)
Locate two 3/16” square balsa strips. These are measured and cut
to form the lower sub-spars near
the leading edge of the wing.
When gluing these two pieces in
place, make sure you again work
from the center of the wing out,
one strip at a time. Be sure to get
plenty of glue for a good bond to
all of the ribs. These pieces will
need to bend slightly around R4.
Step 23 - Wing Assembly (leading edge)
Locate two 5/16” square balsa strips that will be used for the wing’s
leading edge. Measure and cut them taking note that these will
