Insert hinge into the flap. Wipe
with
denatured
alcohol
(methylated spirits) to clean
away any excess glue and
ensure the hinge moves freely.
With all hinges glued into the
flap surface, repeat the hinge
gluing steps for the other side
and insert the flap into the
wing.
Note:
Before the glue is fully
cured, test that the flap moves
freely. If needed, wipe a drop of
denatured alcohol onto each
hinge to free it up.
Next are the control surface
horns found in the “Main Wing”
bag.
Using some coarse sandpaper
(100-150 grit is ideal), rough up
the surface of the tabs on the
control horns (the part of the
horn that inserts into the wing).
This will provide better
adhesion for the glue.
