Great Planes Super Sportster 40 MkII Kit - GPMA0205 - Manual (Page 18)

D 3. With the fuse on a flat surface glue the die-cut 3/32"
balsa aft fuse bottom to the formers and the fuse sides.
D 4. Use the F-7 cross-section on the plans to mark
stringer locations. Center the bottom edge of die-cut 1/8"
ply F-7B on the die-cut 3/16" balsa F-7C, then glue it in
position. Draw a line across the aft edge of former F-7 on
the aft fuse top. Align the aft edge of former F-7C with this
line and glue it to the aft fuse top. F-7B faces toward the
nose of the model.
D 1. Sand or cut off the two little bumps on the inside
of F-2.
D 2. Refer to the side view of the plans. Notice that the die-
cut ply former F-2C is positioned directly over the lower aft
F-2 former and does not use a tab for alignment. Glue it to
the die-cut forward crutch with medium CA.
D 5. Use 6-minute epoxy to glue the die-cut 1/8" ply F-1A
to the forward face of F-1B and to the fuse sides. Clamp it
in place while the epoxy cures. Sand the forward edges
of the fuse sides flush with F-1A after the epoxy
has cured.
D 6. Hold the two halves of the die-cut 1/8" balsa cockpit
deck together. If the tabs on both ends don't match
exactly, turn one of the pieces end-for-end. When the
pieces match, edge glue them together to make the full
cockpit deck. Test fit the cockpit deck between F-3B and
F-4B. It will fit correctly only in one direction. Glue it
in place.
D 7. Cut the 3/16" x 3/8" x 18" balsa aft top stringer to fit
flush with the forward face of F-4 and the forward face of
F-7C. Glue the stringer into the top center notches of
the formers.
D 3. Glue die-cut ply formers F-3B, F-4B, F-5B, and F-6B
into their notches on the fuse top. Use a triangle to maintain
vertical alignment. D 8. Cut and install the 1/8" x 3/8" x 18" balsa side
stringers to fit in the remaining notches from F-4 to F-7C.
Sand the stringer ends flush with F-4.
