There are
lhree
possible
methods
of operating
the ailerons:
One servo
in
the fuselage
Two
seNos in
lhe
fuselage
Two
servos in the wings
Two
aileron servos
give you
the option
of electronic aileron
differential as well
as the
possibility
ol using the
ailerons as
camber-changing llaps (lhese
facilities
must
be
provided
by
your
transmitter).
Nole: lt is
essential
that
you
do not
use solvent-based
adhesives
when
gluing
wood
to styroloam. lnstant
glues
(cyano-acrylate)
such as Zap and Zacki
are
parlicularly
destructive. Use s-minute
epoxy or white
glue.
The wings
Thefirst
stage here is to
sand downthetrailing
edges, using
a long sanding
block. Work
carefully, to achieve
an even
thickness o{ no more
than
1 mm.
Take
care also to maintain
a smooth
airfoil shape. Particular
care
is
needed when
sanding the ailerons;
be sure to keep
the
wings in
theirfoam
negative
shells
when
sanding.
The
leading
edge only
requires
a light final
sanding.
Separate
the aileron from
the
wing
panel
by cutting at righf
angles to the wing leading
edge. Remove
a strip 7mm wide
lrom
both ends of
the aileron, to
provide
clearance for
the
balsa sealing
strips. Sandthe
aileron
leading
edge
perfeclly
straight. The machining
process
leaves
rounded
corners
lo
the machined
slot in
lhe
wing;
lhese should
be sanded
square.
Cut the aileron recess
sealing
strip 45 into
lhe lengths
required,
trim lhe
pieces
to
lit,
glue
them in
place,
and
sand
the
edges
llush.
Please note
that
the top edge
-
which later
forms
the aileron hinge line
-
must
be
lett
sharp.
When
attaching the
sealing strips
to lhe ailerons il isvltalnot
to distort the
panels.
Glue
the sealing
strips
45
to the
ailerons,
and sand down
to
lollow
the wing
section.
Ollerup
the
aileron to the wing
and trim where necessary.
The
gap
between wing
and
aileron should
be
1mm
at
each end.
The following
seclion
describes
two
methods
of actuating
the
ailerons:
1. The
orthodox linkage
using servos in
the
fuselage
and wing-mounted
bellcranks.
2. The
system based
on wing-mounled
servos, instal-
led
at the aileron
posilion.
lnitalling
aileron
bellcranks
Drill
a 3
mm
diameter hole in
the bellcrank
mount 41 where
marked.
Assemble
the bellcrank 42
as
shown
in
the
instructions,
and screw il
to lhe mounl. Be
sure
to oroduce
one left-hand
and one righl-hand
unit.
The
crank must rotate
lreely,
but
without
play.
lf
lhere is a
little
axial
rnovement,
rubthe
inside
surface
ol one of
the two
flanged
bushes
on
400-grit
wet-and-dry
abrasive
paper
to
remove
a
little material.
Adiust
the tighlness
ol the
pivot
screw care{ully, and
secure lhe nut with instant
glue
(cyano-
acrylate) when
you
are satisfied.
De-burr
and
roughen
up the end
of one steel
pushrod
39,
and
pass
it into
the front
bowden cable
outer
lrom
lhe
wing
root
end. Pull
the end of the rod
out of the
bellcrank well
slightly,
lhread a clevis
35 onlo it
and bend the final
2 mm
ot lhe
wire
at righl-angles.
Slide the
link
right
to the end
and
solder it
soundly to the rod.
Connect
the clevis
lo the
bellcrank
(using
the
hole
shown on the
plan)
and
fit
the
bellcrank mount
in the wing well.
Check that
the bellcrank rotates lreely
when
lhe
rod
is
operated. The
bowden
cable outer
should be
pulled
back
f rom
the aileron
bellcrank welljust far
enough to
ensure lhat
the
clevis does not
foul
it
at
maximum
movement.
Check
that the bellcrank
and associated linkage
do not
touch the
foam
at any
point,
and remove
a
little foam
-
as
little
as
possible
-
where
necessary.
The
bowden
cable outer is normally
free
lo
move
inside
lhe
wing. ll
you
find it is fixed,
twist
a small round file into
it at
the
root
end.

Dear modeller,
Many thanks for
purchasing
a
MULTIPLEX
model kit.
MULTIPLEX
kits
undergo a series
ol
material
and
quality
checks,
and
we
are contident
that
you
will be
satisfied
with
the contents of

parts
which
are
no longer
in new
condition. We

MULTIPLEX
are constantly working
on
the development
ol the existing
and
future
range
ol superb
MULTIPLEX models,
and lor
this
reason
we reserve

modity
the
form,
the design and
the
material
of kit
components. Please note
