9. Check the fit of the wing on the fuselage. It must rest tightly
against the fuselage. If the spar fits into the wing and fuselage spar
pockets without any problems, the fit should be perfect. Make sure to
guide the leads for the aileron and flap into the fuselage so they don’t
interfere with the fit.
 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.
E-tips
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.
E-tips
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.
