NOTE: To avoid scratching your new aero-
plane we suggest that you cover your
workbench with an old towel. Keep a
couple of jars or bowls handy to hold
the small parts after you open the
bags.
Please trial fit all parts. Make sure you
have the correct parts and that they
fit and are aligned properly before
gluing! This will ensure proper as-
sembly as the SPARROW HAWK is
made from natural materials and
minor adjustments may have to be
made. The paint and plastic parts
used in this kit are fuel proof. How-
ever, they are not tolerant of many
harsh chemicals including the follow-
ing: paint thinner, cyano-acrylate glue
accelerator, cyanoacrylate glue de-
bonder and acetone. Do not let these
chemicals come in contact with the
colours on the covering and the plas-
tic parts.

HINGING THE AILERONS.

Note: The control surfaces, including the
ailerons, elevators, and rudder, are
prehinged with hinges installed, but the
hinges are not glued in place. It is
imperative that you properly adhere the
hinges in place per the steps that follow
using a high-quality thin C/A glue.
1) Carefully remove the aileron from one
of the wing panels. Note the position of the
hinges.
2) Remove each hinge from the wing panel
and aileron and place a T-pin in the center of
each hinge. Slide each hinge into the wing
panel until the T-pin is snug against the wing
panel. This will help ensure an equal amount
of hinge is on either side of the hinge line when
the aileron is mounted to the aileron.

there is only a slight gap. The hinge is now
centered on the wing panel and aileron.
Remove the T-pins and snug the aileron
against the wing panel. A gap of 1/64" or less
should be maintained between the wing panel
and aileron.
saturate each hinge with thin C/A glue. The
ailerons front surface should lightly contact the
wing during this procedure. Ideally, when the
hinges are glued in place, a 1/64" gap or less
will be maintained throughout the lengh of the
aileron to the wing panel hinge line.
