 12. Remove the control surface and apply a small
amount of hinge glue in each of the holes in the
fixed surface for the hinges. Insert the hinges,
attaching the control surface and fixed surface.
Allow the adhesive to fully cure before proceeding.
 13. Once the hinges are in place, use a paper
towel and water to remove any excess adhesive
that may have seeped out when the hinges were
installed.
 14. Repeat Steps 11 through 13 for
the remaining stabilizer and elevator, as well as
the ailerons and rudder.
Hinging the flaps will take a small amount of trial
and error to correctly position the hinges. Read
through the following steps on positioning the
control surfaces before applying any glue. Improper
installation of the surfaces will cause the control
surfaces to bind, which can cause premature drain
on the battery or even damage to the servos.
 15. Prepare the flap hinges by applying a small
amount of petroleum jelly to the knuckle of the
hinge. Work the hinge so the petroleum jelly
penetrates the hinge. The petroleom jelly will keep
the adhesive from entering the knuckle, causing the
hinge to bind.
 16. Fit the hinges in the flap so the hinge point is
recessed into the flap 3/32-inch (4mm).
 17. Position the flap on the wing. Align the flap
with the aileron and the inboard section of the
trailing edge.
 18. Check that the flap can move through its range
of motion. If there is binding, reposition the hinges
and recheck the flap operation.
