Locate the two aileron control rods
[AC]
in the
hardware bag. Ensure the clevises are screwed well onto
the threaded portions of the rod. Rotate and tug aggres-
sively on the clevises and ensure that they are not loose
on the rods.

Screw the servo into
place with the screws and
grommets supplied. It is
important to install the grom-
mets and screws correctly.
See the manual that came with
your radio for instructions
about your particular servo

Turn the wing upside down. Trial fit the aileron
servo into the servo-mounting cavity located in the centre
of the bottom of the wing. The cavity straddles the wing
joint. You may have to modify the cavity slightly to provide
clearance for the servo and servo wires. Use a hobby
knife to modify the cavity as required. Most servos have
their wire exit guide protruding from one end. Position
your servo so that the wire exit guide is closest to the
leading edge. The servo cavity in the wing has extra room
at the end of the cavity closest
to the leading edge to accom-
modate the servo wiring.
