Completing The Wing - GREAT PLANES Super Sportster 90 Instruction Book

D 5. Clamp the dihedral braces together as shown
in the photo, wipe away any excess epoxy, then
allow the epoxy to fully harden before disturb-
ing the wing.

COMPLETING THE WING

D 1. In the same manner as in Steps 18 and 19
above, glue the top leading edge sheeting in
place.
D 2. Glue the top center section sheeting in
place (Note: As you do so, it will be helpful to
mark the location of the aileron servo open-
ing on the top of the sheeting for future refer-
ence).
D 3. From the 1/4" x 1" x 7" balsa sheet and the
1/4" x 7/8" x 5-7/8" balsa sheet, cut out the trian-
gular tip braces using the pattern on the wing
plan, then glue them to the 1/8" ply wing tips.
D 4. Glue the wing tip and tip brace assemblies
to the tip ribs.
D 5. Glue the 1/2" x 1-1/2" x 2-15/16" balsa rear
tip fairing blocks in place at the trailing edge
of the wing tips.
D 6. Find the two softest 1/8" x 1/4" x 36" balsa
sticks that you previously set aside when build-
ing the rudder.
D 7. Glue 1/8" x 1/4" balsa strips to the top and
bottom of the wing tips as shown in the photos.
Do not be concerned if the sticks break when
they are bent around the curve. Just glue them
down and-sand them to a rounded shape later.
D 8. Use a sanding block with coarse (#60 or
#80) sandpaper to blend the rear tip fairing
blocks to the wing tips, as shown. Also sand
the outside edge of the wing tips to a smooth,
rounded shape.
