Step 55 - Stab Assembly
Locate the two S1
pieces from BP8 &
BP11, the two S2
pieces from BP15
and S5 from BP14.
These form the stab
halves as shown
here. Using your
straight edge as shown will help align the two halves perfectly to
each other. Pin the S2 pieces in place first, then glue S5 in place.
Finally, glue the S1 pieces in place.
Step 56 - Stab Assembly (ribs)
Using the same 1/4” square
balsa strip from step 53, cut the
“ribs” that form the interior of
both stab halves.
Glue these in position when
satisfied with the fit.
Step 57 - Stab Assembly (sheeting)
Locate the four STAB SHEET
pieces from BP18. These are
glued to the top and bottom
of the stab halves after a
light sanding of the stab
assembly. When the glue has
cured, remove the elevator
and attach remaining STAB
SHEET pieces to the other side after a light sanding.
Step 58 - Fuselage Assembly (F1-F5)
Tape the fuselage plan and fresh wax paper on your board.
Locate the F1 from BP12, F2 from BP10, F3 from BP14, F4 from
BP13, and F5 from BP15.
These pieces “jigsaw”
together to form the front of
the fuselage. Pin one piece
down first, then glue and
pin each additional piece in
place. Alignment is critical,
so be careful when doing this.
These next steps require 1/4” square balsa strip and this is
where you have to start thinking about cutting in the correct
order. Make the long cuts first, then work your way down to
the smaller sizes.
Step 59 - Fuselage Assembly (aft framing)
You should have some 1/4” square left from the piece used to
make the elevator/stab ribs. Using that piece first, its time to start
making some of the fuselage
framing.
First, measure, cut and and
glue in the vertical piece,
that runs from the bottom of
F5, along the back of F4 and
down to the bottom of the
fuselage. Then measure, cut and install the longerons that are in
the middle of the fuselage.
Finally, locate F6 from BP14 and install it place between the
longerons as shown on the plan.
Step 60 - Fuselage Assembly (vertical fin)
Locate F7 from BP8 and F8
from BP11. These form the
vertical fin. Fit and glue them
in position as shown.
Then cut the upper and
lower longerons from 1/4”
square balsa, installing them in position. You’ll need to bend these
pieces and hold those bends with several t-pins, similar to what’s
shown in the photo.
Step 61 - Fuselage Assembly (framing)
Now take the time to cut
the remaining framing
from leftover 1/4” square
balsa.
Once all the framing is in
place, double check that
you’ve securely glued each joint.
Step 62 - Fuselage Assembly (plywood sheeting.)
Remove any pins you may have
used in the front section of the
fuselage framing, but don’t remove
the frame from the building board.
Using 150 grit sand paper, lightly
sand the surface of the fuselage
framing to ensure it is smooth.
Locate FS1 from LP3 and FS2 from LP4. These will be the outer
sheet for the front of the fuselage. They are glued in position as
shown and you’ll need to use a fair amount of glue to cover this
area. If using C/A, a thicker viscosity is recommended to give you
working time.
Make sure not to allow glue into any of the cutout areas.
Note - you might want to weight this sheeting down while it is
curing to ensure a good bond to the inner framing.
Step 63 - Fuselage Assembly (weight hatches.)
Locate the two hatch pieces you punched out
from the FS1 and FS2 sheets that were just
glued in place. These will be used later so tape
them in position for now.
Step 64 - Fuselage Assembly (balsa sheeting.)
Locate FS3 from BP6 and
FS4 from BP7. These will
be the outer sheet for the
rear of the fuselage. They
are glued in position as
shown and you’ll need to
use a fair amount of glue
to cover this area. If using C/A, a thicker viscosity is recommended
to give you working time.
