Great Planes Corsair 40 Kit - GPMA0177 - Manual (Page 30)

D 5. Cut a groove from the tail gear hole to the bottom end
of the rudder to allow the rudder to fit tightly against the fin.
D 6. To easily make a fillet along the stab and fin, place a
piece of masking tape 1/4" on both sides of the joint. Apply
balsa filler to the joint using your finger. Remove the
masking tape. Then wet your finger and wipe across the
fillet to smooth it out. After the filler has dried lightly, sand
the fillet with 320-grit sandpaper.
D 2. Use the template on the plans as a guide to cut the
belly fairing sheet from 1/16" x 3" x 18" balsa (F16). Sand
the edges of the sheet so that it blends into the bottom
sheeting on the wing. Glue the belly fairing sheet to the
wing, then use balsa filler to finish blending it into the wing.
LI 3. Cut a 4-1/4" long piece from the 3/32" x 1/2" balsa cap
strip balsa to make an aft belly fairing end. Cut a notch in
the center so that the belly fairing end fits over the wing
plate. Glue the aft belly fairing end to the top of the wing
plate and wing, flush with the TE. Leave approximately
1/16" between the belly fairing end and former F-5. Sand
the top of the belly fairing end so that when a 3/32" sheet is
applied, it will be flush with the fuse bottom sheeting.
Note: Before working on the belly fairing, we suggest that
you remove the wing from the fuse and insert a layer of
waxed paper between former F-2 / LE joint and F-5 / TE
joint of the wing. This will help prevent the wing from being
accidentally glued to the fuse.
D 1. Fit the 1/8" die-cut balsa belly fairing front (FO6) on
the LE of the wing. Leave a gap of 1/16" between the BF
and F-2. Align the belly fairing front with former F-2 and
glue it in place.
D 4. Cut two 7" long pieces from the 3/32" x 1/2" balsa cap
strips to make aft belly fairing sides. From the plans, use
the template as a guide to cut the belly fairing sides. Sand
the belly fairing sides to achieve a close fit to the wing
bottom. Glue the sides to the wing and aft belly fairing end.
