of

tube
hole in

(remainderof

and
glue
it
to the rudder. Sand both
blocks to follow the
curvalure ol the
fuselage
at lop and
bottom.
The next
stage
-
rounding
offthe rudderleading
edge
-
must
be carried out
with
particular
care, as
the
fit
of the rudder to
the
lin is
crucial to the appearance of
the
whole
tail
group.
Keep strictly to the cross-sections
shown, and check the fit
continually by oflering the rudder
up to the
fin.
Cut the
holes in
the fin
post
to take the rudder hinge
plates
57. lt is best
to
pilot-drilllhe
holes with
a
4 mm
drill, then
{ile
them out to shape. Transfer
the
hinge
plate positions
to the
rudder.
Removelhe
pivot
rod
56 and
cut a
horizontalslol
across the
rudder leading
edge at the
marked
points,
using a thin
hacksaw blade. File
out the slots to
a
width
of
4 mm
using
a
needle file. The
slots must be
deep enough to cut right
lhrough the
pivot
tube, but take
care
not
to cut into the wood
behind the tube.
Insert
the
pivot
rod 56 in
lhe rudder, andthread it
through the
rudder hinge
plates.
Check that the hinge
plates
rotate
f reely on
the
pivot
rod.
Fit
the
rudder
complete with hinges into
the
f in,
check for fit,
--
and trim
the
plate
slots
il
necessary.
The rudder must
be installed
central to the fin. To
ensure
that this
is
the case, lit
a thin strip of card
between
lin
and
rudderon
both sides. The
rudder
must
be not
be
pushed
in
to the
point
where
it
cannol detlect to either
side:
it must
have
at
least
30 degrees lree movement
each
way.
Apply
5-minute epoxy
to the
rudder
hinge
plates
and the
fin
post,
and
plug
them in
as already
described.
Tape
the
rudder in
position
while
lhe
glue
is hardening.
Whenlheglue
has
set, check that lhe rudder moves freely
to either
side.
Cut the
pivot
rod
to
the correct
length
and bend the
final
5mm at right-angles. You will f ind
it necessary
to bevel the
top
ol
the rudderto
clear the elevalor linkage
(see
drawing).
Slide the
steel
pushrod
49 into
the
rudder
bowden
cable
outer and
mark
where it
crosses lhe rudder.
Cut a slot
lor
the
rudder horn 29
(bored
1 .3 mm
diameter). Apply
tape
around
the
horn
slot to
prevenl
excess
glue
soiling
the
surface, and
epoxy the horn in the
slot,
leaving
two linkage
holes exposed.
Check that lhe horn
does
not rub
on the
-
inside
of the
|uselage.
Bend
lhe
final
8 mm
of the rudder
pushrod
at right-angles,
and connect it
to the rudder
horn.
The connection is
quite
secure wilhoul
any
lurther
form of
keeper.
Check that the rudder
still
moves freely
to both
sides
when
the tailplane is in
place.
The use
of the
rudder hinge
plates
57 allows
you
to remove
the
rudder lrom
the fuselage without
causing
serious dama-
ge
to the fuselage
(after
a
hard
landing,
or
tor
transport).
When
assembling the model,
simply
press
the rudder hinge
plates
into
place.
The canopy
Thelitof
the canopy is oneof

Tape
the cabin
lrame
5 on the luselage
(there
should
be a
gap
about
1mm
wide all round
to the
fuselage
edge),
and
drill
the
3.5
mm
diameter
hole
at the tront
at the
marked
ooint.
Drillthe 3 mm diameter hole
at the
rear, working
at the angle
shown on the
plan.
Drill
both
holes right
through the
frame
and the cabin flange. Insert the rivet 10 in the lront hole,
check that
it fils
snugly, then
remove
lhe cabin frame and
glue
the
rivet into
the
trame.
The
canopy
latch
9
is
installed next. Drill
outthe
rear hole
in
the
fuselage
flangeto
5
mm
diameter, andchecktha he
latch fils well. Markthe
position
of
the slot
forthe
actuating
pin
(about
2 x 10 mm)
using a felftip
pen,
and
lile
the slot
out
neatly
using a small needle file,
after drilling
a series of
1 .5 mm
pilot
holes.
Check that
the
latch tits,
and
file
out
the
holes if necessary.
Roughen
up the inside
ol the
fuselage
where
the
latch fits,
and
apply a drop of oilto the
pin
at each
exposed
point.
The latch
can
now
be lack-glued in
the
luselage using
s-minule epoxy. When
the
glue
has
set,
check
lhat lhe
latch
still works,
then apply a
fillet
of
slow-
setting epoxy,
preferably
thickened as before,
to secure
it
permanently.
Take
care that
no
glue gets
inside
the
mechanism:
leave
the
luselage
inverted while
the resin
cures. Retract the latch
pin
and sand the front face
of lhe
latch body flush with
the GRP tuselage llange. Now
place
the
cabin
lrame
on the
luselage,
andcheckthat the latch
pin
retains
lhe frame reliably. Trim
out the hole in
lhe cabin
frame il necessary
until
this
is
the case.
Cut out the inslrument

and sand the edges

Apply

lransfers,
with

taking
care to
avoid trapped
ak bubbles. Trim
the
instrument
panels
to
fit
inside
the binnacles,
pushing
them
in
slightly to leave
a
projecting
frame.
Fix them in

with
instant

use an activator spray il necessary.
Place

lf

chance to do
so.
To

Position the
canopy
lrame
on the fuselage
and
fix
it in

with
the
latch. lf
the centre
of the
lrame
does not rest
squarely on the tuselage flange, hold
it down by
tying thin
thread
(sewing
cotton) round
the fuselage;
don'l
worry,
lhe
thread
can easily be
removed
again
later. Tape
lhe
ends ol
the lhread to
the underside ol the fuselage.
Place the
canopy over lhe frame
and
position
it

Using a

pen,
mark
a
line
on the

Clean lhe canopy moulding

Clear conlact cement is

Apply the
