Step 82 - Fuselage Assembly (fuse sides)
Locate both balsa fuselage
sides from back in step 73.
These are now glued to the
fuselage box as shown here.
The former’s extended tabs
will help you align these
pieces. Make sure they are
firmly and completely pushed
up against the plywood box sides while the glue cures - no gaps.
Note that the extended tabs on F4 and F5 will still extend past the
fuselage sides - this is intended.
Step 83 - Fuselage Assembly (fuse sides.)
Once the glue has cured from the previous step,
use some tape to carefully bring the rear edges
of the fuselage together as shown here. Once
aligned, lightly tape them together to aid in the
following steps.
Notice the shape of the fuselage sides in this
photo. During the next few steps, make sure the
fuselage sides remains aligned like this. It will be
easy to misalign this section to the left or right
when gluing in the formers. If this happens, it
won’t be an easy thing to correct.
Step 84 - Fuselage Assembly (F7)
Locate F7 from BP5. Carefully insert it
in place, with it’s tabs inserted into the
pre-cut slots in the fuse sides. Make sure
that the shorter wide cutout and round
holes are aligned towards the top of the
fuselage.
Glue in place.
Step 85 - Fuselage Assembly (F8)
Locate F8 from BP6. Carefully insert it in
place, with it’s tabs inserted into the pre-
cut slots in the fuse sides. Make sure that
center holes are aligned towards the top of
the fuselage.
Glue in place.
Step 86 - Fuselage Assembly (TD4, TD5, TD6 & TD7)
Locate TD4, TD5, TD6 and TD7 from BP6. These sub-formers are
the basis for the turtledeck. They are fitted in place in numerical
order. Note to help in fitting them in place, the side-to-side fit is
intentionally large (sloppy). This allows you to fit in one side, then
gives you the clearance to slide it in slot on the other fuselage side.
Then center the piece between the sides as shown here. Make sure
each TF is 90° to the fuselage side when gluing them in place.
Also take care as these pieces are fragile, and will remain so until
the stringers are attached in the next steps.
Step 87 - Fuselage Assembly (side stringers)
Locate two 1/8” square balsa sticks to form the side stringers.
These will run from F3 back to F8, on the top of the fuselage side
sheets.
Measure and cut them to length, then working from one end, slowly
glue the strips in place, working a
little at a time. Make sure the strip is
fully inserted into the pre-cut slots in
each former. This will allow allow the
fuselage sides to be roughly 1/16”
proud of the stringers, making room
for the sheeting applied in future
steps.
Step 88 - Fuselage Assembly (turtledeck stringers)
Using scrap 1/8”
square balsa sticks
first, measure and cut
the three stringers for
the turtledeck.
Glue these in place as
shown, making sure
they are fully inserted
into the slots.
Step 89 - Fuselage Assembly (TD1)
Locate TD1 from BP5.
This is the sub-former
where the instrument
panel (TD2) will be
attached.
Refer to the plans as
where this should be
glued in place. This
location isn’t critical
and can be moved a
bit forward or rearward if desired. When you have a spot picked
out, make sure it is aligned properly and 90° to the top of the
fuselage sides while the glue cures.
Step 90 - Fuselage Assembly (front stringers)
Using scrap 1/8” square balsa
sticks first, measure and cut
the three stringers to run from
F4 to TD1.
Glue these in place as shown,
making sure they are fully
inserted into the slots.
