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.

 

3) Slide the wing panel on the aileron until

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.

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.

Note:

 

4)Deflect the aileron and completely

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.

Note:

The hinge is constructed of a special
material that allows the C/A to wick or
penetrate and distribute throughout the
hinge, securely bonding it to the wood
structure of the wing panel and aileron.

              To avoid scratching your new aero-
plane we suggest that you cover your work-
bench 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
assembly as the  

DECATHLON

 

 

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. However, they are
not tolerant of many harsh chemicals includ-
ing the following: 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 plastic parts.
