Required Tools and Adhesives

Thin CA (Cyanoacrylate) Adhesive

We recommended you work on one wing half at
a time for all wing related assembly steps; this
will ensure left and right components aren’t
accidentally mixed up.
Alternately, you can mark one side of the wing
with some masking tape for easy identification.
Some assembly steps are done from the top
side of the wing and some are done from the
bottom side so it’s easy to get confused.

Separate the aileron and the flap from the main
wing. Ensure the hinges are well seated and
centered in their corresponding slots. Replace
the control surfaces and flex the hinges back
and forth several times to loosen them. Remove
the control surfaces again.

}}}}
Starting with the aileron (outboard control
surface), insert into the wing and align it to the
desired position. Ensure there is a small gap
between the aileron and outside of the wing and
there is no rubbing or binding.
}}}}
Tip: the hinges can be held in position with T-
pins if they shift when inserting the control
surface. Remember to remove the T-pins before
bonding the hinges.
}}}}
Note: If any hinge slots are missing hinges add
them from the supplied spare hinge bag [H5].
}}}}
Using thin CA adhesive with a fine applicator
place a few drops on each side of the hinges.
The use of thin CA ensures the adhesive is
wicked up the complete surface of the hinge for
a tighter bond. Avoid the use of accelerator in
this joint since you don’t want to cure the
adhesive before it completely coats the hinges.

Once the aileron has been hinged repeat the
step with the flap (inboard control surface).
Ensure there is a small gap between the aileron
and the flap and there is no rubbing or binding.
Additionally, ensure the flap does not extend
past the inner edge of the wing to avoid
interference with the fuselage when the wing is
mounted.
}}}}
Repeat the procedure for the opposite wing. Set
the wings aside until the adhesive has dried
thoroughly.
}}}}
Once the adhesive is dry flex all the control
surfaces several times and give them a light tug
to make sure they are properly bonded.
