The

lor
the

47
only
needs to be cleaned up
on the
inside with a flat
file. Thoroughly roughen
up
the
inside
of lhe
fuselage around these openings, to ensure a
sound
joint
when
lhe
wing
joiner
is bonded into

Glue
the two transverse struts
l6togetherwilh their edges

glue
has set, bevel the ends to
match
the
fuselage curvature atthe

fairings,
check
that
the strut
fits
accurately, and
glue
it in

Take care
not to obstruct the

Sandpaper the ends of the
rectangular brass tubes and
assemble
them as shown
in
lhe drawing, slipping
the two
side cheeks
into
place.
Check
that the tubes are the
right
way round
-
right-hand
blade
to the front, left-hand blade to

Adjust
the brass lubes until
only one end ol each
projects
out ofthe fuselage.
The
other end
is left
about 5
mm
short of the opposite
fuselage
side.
The
wing
dihedral
is
determined
by the spacing o{ the side
cheeks.
Numerous test
llights have
shown that a dihedral
angle ol
7
degrees
is
the optimum
ligure
lor

We strongly advise against
reducing
or
increasing the dihedral
lrom this
ligure.
(Dihe-
dral
=
3.5 degrees

Total dihedral
=
Tdegrees).
Placethe rectangularbrass lubes

shifl the side cheeks until
the dihedral
is
correct.
The two
cheeks
must be equi-distant

Mark

Caution:
nevertighten lhe clamping screw unless

De-greasethe wing

dry
(no

Fit

lhreading lhe clamp and side
cheeks
into

inside
the
fuselage,
and
plug
in
the
wings.
Check thal
the wings line up wilh the root fairings,
and lrim back the apertures
in
the
lairings
until alignmenl
is
exaclly
right.
Check that lhe
wing
ioiner
components are aligned accor-
ding
to the marks, and
glue
the side cheeks lo the lubes
using s-minute epoxy. Spot-glue
the
joiner
assembly
in
place
using s-minute epoxy
(do
not
glue
the assembly
permanently).
Leave
the
glue
lo set
lor
about litteen
minules.
Carelully rernove the wing
panels
and
joiner
blades.
Apply
tape lo
the outside of the fuselage over the wing root
fairings, covering any
gaps
where
glue
might
be squeezed
out.
The wing
joiner
assembly can
now
be
permanently
bonded
into
the
fuselage. Use
slow-setting
epoxy forthis, such as
UHU
plus
or
MULTIPOXY,
lhickened
with
chopped
glass
rovings, micro-balloons or similar.
The
best
melhod is
to
work
on one
side at a time, and
leave
lhe fuselage
resting
on that side until the
resin has
cured.
This eliminates any
risk ol lhe
resin
getting
into
the
wing
joiner
assembly.
Be
sure
to apply
plenty
of the
resin
/
libre mixture round
the
ends of the brass lubes
which
do
not reach
to the
fuselage
side.
When
the
resin has
cured, sand
back the ends ol the
joiner
lubes
llush with
the
fuselage root lairings. Take
care
not
to
damage the fuselage.
Installing the wing

The nexl

is lo
glue
the wing

tely slightly
oversize,lo allow a degree ol adjustment, sothis
task
must
be
carried out
in
conjunclion
with
the
fuselage.
The blades should
reach
to the
far
end of the
rectangular
tubes.
Markthe

Thoroughly roughen
