Epoxy
Use a small piece of rough sandpaper to
scu the hinges for better epoxy adhesion.
Do this to all aileron hinges.
Remove the ailerons from the wing and
remove the hinges.
Apply epoxy to each hinge where it will
be inserted into the ailerons. Tip: Apply
some petroleum jelly to the metal pin
hinge area to keep epoxy from interfering
with smooth operation of hinge.
Please see pictures below.

Insert all four hinges in the ailerons at
this time. Make sure hinges move up and
down in right direction and not side to
side !
Be sure to test the aileron hinges once
you insert them. Ensure that the hinge
pockets line up, and that the hinges move
freely before the epoxy dries.
Check the t of the aileron to the wing.
e top of the ailerons will align to the
top of the wing. Make sure movement is
smooth and bind free.
We prefer 30-minute epoxy to allow
enough working time during the hinge
installation.
Apply epoxy into each of the holes in the
ailerons using a spare piece of pushrod
wire or toothpick.
Make sure to use enough epoxy so it
securely adheres the hinge to the surfaces.
Do not use an excessive amount of epoxy
when gluing the hinges so that it expels
from the hinge area.
