Step 53 - Fuselage Assembly (1/4" stringers)
Locate two of the 1/4" sq. balsa
strips. These are cut to length,
running from the LG1 you just
installed on the bottom of the
fuselage, back to the start of the
horizontal stab cutout.
Make sure these are pushed
completely into the notches of
each former and glued to the
outer sheeting.
n
Step 54 - Fuselage Assembly (tail surfaces)
Move the fuselage aside as we have
to do one piece of housekeeping first.
Grab the vertical fin, horizontal stab,
and one of the 90° triangles.
It's time to glue the fin to the stab.
Place the stab so the hardwood
tailwheel mount is against the board
(not-seen).
Test fit these pieces, then sand as necessary to get a good, slop-
free fit. When you're satisfied, apply glue where the two pieces
touch, then attach the fin, using the triangle as a guide to make
sure it is perfectly perpendicular.
n
Step 55 - Fuselage Assembly (tail surfaces)
Place the fuselage back on the top view of the fuselage, held by
the punch-outs.
Then, test fit the tail surfaces into position, as shown here. It should
slide completely into the pre-cut notch in the fuselage, up against
F6.
Sand as necessary for a good,
slop-free fit. Then when satisfied,
apply glue where the pieces
touch and permanently attach
the tail surfaces to the fuselage,
as shown here.
n
Step 56 - Fuselage Assembly (1/4" stringers)
Locate more of the 1/4" sq.
balsa strips. These are cut to
length, running from the rear
of the wing saddle, to the rear
of the fuselage.
It's ok to piece these together,
as they're not structural.
You'll also need to sand the
width slightly to fit around the vertical fin.
Make sure these are pushed completely into the notches of each
former and glued to the outer sheeting.
n
Step 57 - Fuselage Assembly (FS6)
Locate FS6 from BP4. Trim the
support from the opening at the
narrow end.
Now CAREFULLY test fit this around
the vertical fin, so it lays against
the fuselage and stringers you just
installed. Sand as necessary for
Construction Manual
a good, slop-free fit. Then, when satisfied, apply glue where the
pieces touch and glue it in place.
n
Step 58 - Fuselage Assembly (FS6)
Here's another spot where you need
to do some of that thinking and
planning stuff.
If you're using a flexible pushrod
system, such as Dubro's Lazer rods,
now is a good time to route the outer
housings through the fuselage and
glue them in place.
You'll note that there are small pre-
cut circles in each of the F5, F6, and
F7 formers, as well as cutouts in FS6,
on each side of the vertical fin. These
are the areas where you will slide the
outer tubing through. Make sure you
glue them to each of the formers so they won't move and/or rotate
over time.
n
Step 59 - Fuselage Assembly (top sheeting)
Well, I do declare, it's now time
to sheet the bottom of the
fuselage - cross sheeted, that is.
With the fuselage still held in
place and nicely symmetrical,
locate some of the un-cut 1/8"
balsa sheeting.
Now you'll use this to start
the sheeting on the top of the
fuselage.
Start at the rear of the fuse, up against the front edge of FS6, and
work your way forward to the rear of the wing saddle, as shown
here - a piece at a time.
n
Step 60 - Fuselage Assembly (rear, bottom sheeting)
Now, flip that fuselage over, and
continue your cross-sheeting
exercise. Start at the rear of the
LG1 block and work your way
back to the leading edge of the
stab - a piece at a time.
n
Step 61 - Fuselage Assembly (1/4" stringers)
While the fuselage is up-side-down,
use more of the 1/4" sq. balsa
strips to form the stringers that run
from the LG1 block to the front of
the fuselage.
Just as before, make sure these
are pushed completely into the
notches of each former and glued
to the outer sheeting.
Again, remember you can piece
these together from smaller scraps.
