STEP 3: CHECKING THE WING CENTER-SECTION JOINT
❑
Once the epoxy has fully cured, remove the masking tape and double-check the center-section joint. If any gaps are
present, mix a small quantity of 30 minute epoxy and carefully fill any remaining gaps. Quickly remove any excess epoxy,
using a paper towel and rubbing alcohol, and allow the epoxy to thoroughly cure.

Do not omit this procedure. The wing panels should fit together tightly, but it's possible to have some
small gaps that appear after the epoxy has cured. To make the wing center-section joint as strong as possible, it's
important to fill any gaps, using 30 minute epoxy.
STEP 4: INSTALLING THE BALSA LEADING EDGE SUPPORT
❑
Test-fit the balsa leading edge support to the leading edge
of the wing. It should fit firmly against the leading edge of the
wing and the edges of the leading edge support should be even
with the profile of the wing.

To get a perfect fit, you may need to slightly
enlarge and/or elongate the predrilled holes in the leading
edge support to fit around the wing hold-down dowels.
❑
When satisfied with the fit, cut away and remove the covering material from the gluing surfaces, then glue the leading
edge support into place, using a generous amount of 30 minute epoxy. Remove any excess epoxy, using a paper towel
and rubbing alcohol, and hold the leading edge support in place, until the epoxy completely cures, using masking tape.

Using a modeling knife, cut away and remove the covering material from over the top and bottom of the two predrilled
holes in the trailing edge of the wing. The holes are located approximately 7/8" in front of the trailing edge and 2" out
from the centerline.
