The
Leading
Edge
of
the
Aileron
The
leading
edge
of
the
aileron
is
rounded
over
with
sandpaper
to
make
the
aileron
movable
with
a
minimum
gap.
The
trailing
edge
of
the
wing
in
that
section
is
left
flat.
FUSELAGE
CONSTRUCTION
The
fuselage
is
built
as
two
separate
box
structures,
the
front
balsa
sheet
and
ply
area
and
the
rear
built
up
section,
which
are
then
joined
over
the
plan.
This
system
not
only
keeps
each
stage
simple,
but
it
also
helps
to
ensure
a
straight
fuselage.
Fuselage
Construction
Detail
Building
of
the
rear
of
the
Fuselage
Begin
by
building
two
rear
fuselage
frames
over
the
plan
and
allow
to
dry.
Select
hard
balsa
or
basswood
for
the
longerons.
Join
the
two
frames
over
the
plan
with
cross
braces
and
the
tailskid
mount.
Check,
check
and
check
again
that
this
and
ALL
other
structures
remain
perfectly
straight
and
square.
Building
of
the
front
of
the
Fuselage
The
front
half
of
the
fuselage
is
a
box
structure
made
from
1/8”
balsa
and
plywood.
Assemble
the
balsa
sides
from
the
two
laser
cut
pieces.
Add
the
1/32”
plywood
doubler
to
the
inside
surfaces.
Using
the
plan
as
a
guide,
build
the
fuselage
over
the
top
view
adding
the
sides
to
the
F1
and
F3
formers.
When
secure,
remove
from
plan
and
add
the
basswood
crosspieces
and
Former
F3a.
Add
the
undercarriage
mounts
F1C
and
F1D.
The
top
deck
formers
are
added
and
the
turtle
decking
is
glued
in
place.
1/16
th
Balsa
sheeting
covers
the
front/top
of
the
fuselage
between
formers
F1
andF2.
The
area
aft
of
this
is
dealt
with
later
in
this
manual.

Adjust
the
holes
if
necessary.
Laminate
the
two
plates
together.
Find
the
8
3/16”
balsa
motor
core
pieces.
Laminate
them
together
–
one
section
of
5
pieces
and
another
section
with
3
pieces.
Check
the
plans
for
correct
order
of
pieces.
Use
the
2
‐
56
screws
to
line
up
the
pieces
properly.
Laminate
the
1/16”
ply
pieces
to
the

section,
with
the
1/8”
notched
piece
between
the

Find
the
three
different
sized
circular

Glue
the
rolled
paper
around
the
cylinder
cores.
