Wing
•
The wing consists of three panels: the centre section, which is screwed to the fuselage, and the
two outboard panels which plug into the centre section. All the wing panels are of conventional
built-up construction, and are supplied already film-covered. The ailerons are attached using hinge
tape, and the dihedral angle between the wing panels is pre-defined.
•
The wing centre section is attached to the
fuselage by a central retaining screw. Re-
move the film over the screw-hole on the un-
derside of the centre section using a hot sol-
dering iron; the tip of the soldering iron sticks
the edges of the film down at the same time.
Glue the beech dowel in the central hole in
the leading edge; it should project forward by
about 15 mm.
•
Now remove the film over all the other open-
ings: the cable holes on the underside of the
centre section and the tip ribs, and those in
the root ribs of the outboard wing panels.
•
Remove the film over the servo wells on the
underside of the wing, again using a sol-
dering iron.
•
Cut off the servo plug, leaving it attached to
a short length of cable. Place the aileron ser-
vo in the servo well and thread the lead from
the servo well through the sleeve and out of
the root rib. Solder the plug to the servo lead
again as shown: cut off the servo lead so
that only about 20 mm projects from the root
rib, including the connector.
•
The aileron servos are installed using the
plywood mounts supplied. To determine their
exact position, fit the mounts on the servo
and position this assembly in the servo well
'dry' (without glue). You can now mark the
exact position of the servo mounts.
•
Glue the servo mounts in the wing using
thick cyano or epoxy; allow the glue to set
really hard before installing the servos again.
Fix the servo to the mounts using hot-melt
glue or a retaining screw.
•
Two 60 cm extension leads (terminating in
sockets) must be installed in the wing centre
section in order to connect the aileron servos
in the outboard panels to the receiver. The
sockets themselves can be glued in the
opening in the facing ribs. If you opt to do
this, take care not to allow glue to run into
the socket.
