Great Planes P-51D Mustang 40 Kit - GPMA0175 - Manual (Page 25)

D 14. Find the die-cut 1/8" ply hold-down plate TRI-
PLERS, and epoxy them in place around the hold-down plate
and F-4C. The aft edge of the triplers should be securely
glued to F-4.
D 17. From the remaining 3/32" x 3" balsa sheet, cut
pieces of cross-grain sheeting, and glue them to the bottom of
the air scoop, from F-5 to F-4B. Sand the edges of the bottom
sheeting to blend with the scoop sides.
D 15. From the 1/4" x 1/4" x 30" balsa sticks, cut three air
scoop stringers approximately 9-1/4" long. Glue these
stringers in place from F-5 to F-4B. If the balsa is too hard to
permit easy bending, make several saw cuts, as shown in the
photo. Sand the ends flush with F-4B, and sand the edges of
these stringers to blend with the edges of F-4B and F-5B.
D 16. Glue the die-cut 1/8" balsa rear scoop sides in place,
then trim and sand the edges to blend with the stringers and
F-4B. The photo for this step is at the top of the next column.
D 18. Use 30-minute or 5-minute epoxy to securely glue
F-l to the fuse sides, holding with clamps or tape until the
glue has firmly set. NOTE: Before the glue sets, double
check to make sure F-l is properly aligned with the top and
bottom edges of the fuselage, and fully back against the fuse
doubler and spacer. After the glue has fully hardened, sand
off the front of the fuse sides flush with the front of F-l.
