WHEELS
Gluing
the
ply
sides
on
the
¼
“balsa
core
makes
the
basis
for
the
wheels.
Use
the
brass
hub
for
alignment.
Epoxy
the
hubs
in
place
and
add
a
sufficient
amount
of
epoxy
around
the
base
of
the
hub
to
reinforce
the
connection
of
the
hub
to
the
ply.
Plywood
reinforcing
hubs
are
provided
that
are
to
slip
over
the
brass
tubing
as
shown.
Alternatively,
gluing
an
additional
½”
square
piece
of
scrap
1/8”
balsa
with
a
hole
drilled
in
the
center
can
be
substituted.
Next,
CA
glue
the
neoprene
cording
together
to
from
a
“tire”.
Use
thin
CA
sparingly
as
the
CA
bonds
very
aggressively
to
the
rubber.
Press
the
CA
wetted
ends
together
for
an
instant
bond.
The
best
way
to
align
the
ends
is
to
glue
them
while
they
are
in
place
on
the
wheel.
Then
attach
the
tires
to
the
wheels
and
CA
in
place.
A
thin
bead
of
CA
around
the
rim
makes
for
a
secure
tire.
Paper
cones
are
cut
out.
Use
a
ballpoint
pen
to
score
each
line
on
the
back
to
make
an
impression
of
“spokes.”
It
is
helpful
to
do
this
operation
on
a
paper
tablet
so
that
the
pen
makes
a
good
crease.
Fold
the
paper
along
the
crease
lines
to
exaggerate
the
raised
lines.
One
of
the
sections
forming
a
wedge
is
cut
out.
Make
cuts
to
the
center
of
the
circle
along
a
pair
of
the
spokes.
Close
the
paper
cut
‐
out
to
form
a
cone
and
tape
the
joint
inside
the
cone.
Completed
Wheels
The
inside
cones
may
now
be
attached
to
the
wheels.
The
outside
cones
may
be
attached
at
this
point
if
wheel
collars
are
to
be
used.
Alternatively,
after
installing
the
wheels
on
the
landing
gear,
a
washer
may
be
soldered
to
hold
the
wheel
in
place
and
then
the
cone
is
attached.
This
method
makes
a
very
nice
scale
appearance.
INSTALLING
THE
RADIO
CONTROL
GEAR
Aileron
Servos
Aileron
servos
are
mounted
in
wing
and
attached
with
short
threaded
rods
to
the
ailerons.
Use
a
“Y”
wiring
harness
connector
to
wire
the
servos
to
a
single
radio
connection.
If
differential
aileron
throws
are
desired,
rotate
each
servo
horn
forward
about
20
degrees,
while
maintaining
the
neutral
position
of
the
aileron.
This
should
counter
any
adverse
aileron
yaw.
Battery
Tray
After
all
the
above
has
been
placed,
mount
the
battery
tray
made
from
1/8”
balsa
and
use
the
battery
position
to
balance
the
model
as
shown
on
the
plan.
ASSEMBLY
Wing
Using
Locating
Dowels
And
Aligning
Wing
Panels
The
first
task
is
to
epoxy
the
lower
wings
accurately
onto
the
fuselage.
Use
5
‐
minute
epoxy
for
this
task.
Apply
epoxy
to
the
wing
rib
that
meets
the
fuselage.
Attach
the
wings
to
the
fuselage.
Use
the
locating
dowels
to
assist
with
aligning
the
wing
panels.
Allow
epoxy
to
set.
After
the
lower
wings
are
attached,
the
struts
are
inserted.
Use
music
wire
lashed
and
CA
glued
to
the
laser
cut
ply
cabane
struts
as
strengtheners
and
attachment
points
to
be
epoxied
into
hard
bass
blocks
in
the
top
wings.
The
top
wing
is
added
and
epoxied
in
place.
Fitting
Tail
Surfaces
The
horizontal
stabilizer
is
in
two
halves
and
has
tabs
that
fit
into
slots
in
the
side
of
the
fuselage.
Insert
the
two
halves,
and
dry
fit
the
elevator
using
CA
hinges.
The
elevator
serves
as
an
alignment
tool
so
that
the
horizontal
stab
can
be
CA
glued
in
place.
The
vertical
stabilizer
also
fits
into
a
slot
in
the
top
of
the
fuselage
formed
in
F7.
Control
Horns
On
The
Pushrod
Ends
Slip
the
control
horns
onto
the
wire
pushrod
ends
and,
with
both
the
servos
and
the
control
surfaces
centered,
glue
the
horns
into
their
slots.
Fitting
the
rigging
wires.
Use
strong
thread
or
Kevlar
fishing
line
or
elastic
beading
cording
to
simulate
rigging
wires.
Use
small
screws,
