11) Once the epoxy has fully cured, double
check the center section joint. If any gaps are present,
mix a small amount of Kwik Bond 30 Minute Epoxy
and carefully fill any remaining gaps. Remove any
excess epoxy and allow it to cure thoroughly before
proceeding.
INSTALLING THE WING DOUBLER
q
12) Set the plywood wing doubler in place on
top of the wing. The back edge of the doubler should
be even with the trailing edge of the wing and the
sides of the doubler should overlap the centerline of
the wing equal amounts. See photo # 5 below.

13) While holding the doubler in place, use a
pen and draw around the doubler to outline it onto
the top of the wing.

q
1) Using a modeling knife, remove the cover-
ing from over the two predrilled wing hold down
dowel holes in front of the wing saddle. One hole is
located on each side of the fuselage 9” behind the
front of the fuselage and 1/2” down from the top of
the fuselage.
q
2) Remove the covering from over the two pre-
drilled wing hold down dowel holes in back of the
wing saddle. One hole is located on each side of the
fuselage 20-3/8” behind the front of the fuselage and
1/2” down from the top of the fuselage.
q
3) Slide one wing hold down dowel through the
two front holes and one through the two back holes.
Center the two dowels in the fuselage. Both ends of
each dowel should protrude from the fuselage sides
equal amounts. See photo # 6 below.
q
9) Mix a generous amount of Kwik Bond 30
Minute Epoxy. Apply a thin layer of epoxy to the
exposed half of the dihedral brace, the inside of the
plywood box in the second wing half, and the entire
surface of both root ribs. Make sure to use enough
epoxy to fill any gaps.
q
10) Slide the two wing halves together and care-
fully align them at the leading and trailing edges.
Wipe away any excess epoxy using a paper towel and
rubbing alcohol. Use masking tape to hold the two
wing halves in place until the epoxy fully cures. See
photo # 4 below.
q
14) Remove the doubler. Using a modeling
knife, carefully remove the covering from just inside
the outline.
When cutting through the covering, cut with
enough pressure to only cut through the cover-
ing itself. Try not to cut down into the wood.
Removing the covering will allow a better bond be-
tween the two parts. Glue does not stick well to the
covering material used on R/C models, so always re-
member to remove the covering from any surface to
be glued.
q
15) Glue the doubler to the wing using Kwik
Bond Thick C/A. Hold the doubler firmly in place
until the glue fully cures.
