10. Remove the wing and spar from the fuselage.
Apply a thin coat of petroleum jelly to the fuselage
around the wing socket. This will keep you from
accidentally gluing the wing to the fuselage during
the following procedure.
Before mixing any epoxy, make sure to read through
and understand the following steps. It is important
to perform these steps before the epoxy fully cures.
11. Mix 1/2 ounce (15mL) of 15-minute epoxy.
Apply the epoxy to the spar pocket of the wing
using a mixing stick.
12. Use an epoxy brush to apply epoxy to the
front, back, top and bottom of the spar where it fits
into the wing.
13. Slide the spar into the spar pocket of the wing,
making sure it is oriented correctly. Use a paper
towel and rubbing alcohol to remove any excess
epoxy from the wing and spar.
Epoxy will ooze out from the spar pocket of the
wing. If epoxy does not ooze out, not enough
epoxy was used to glue the spar into the wing.
14. Before the epoxy cures, slide the wing into
position against the fuselage. Keep the wing tight
against the fuselage until the epoxy fully cures. You
can use a 9/64-inch ball driver to lightly tighten
the screws to secure the wing joiner in the fuselage,
and low-tack tape to hold the wing in position until
the epoxy has cured.
15. Once the epoxy has cured, remove the wing
panel from the fuselage. Repeat steps 4 through 14
to install the remaining wing panel to the fuselage.
16. Once the epoxy has fully cured and both wing
panels have spars, remove any petroleum jelly
residue from the fuselage and wing using rubbing
alcohol and a paper towel.
