Great Planes Corsair 40 Kit - GPMA0177 - Manual (Page 27)

D 12. Insert the fin in the slots in formers F-8B and F-9B.
Glue the 1/2" x 7/8" x 3-7/16" balsa filler block (F20) on
each side of the fin. Do not glue the blocks to the fin. After
gluing the blocks in position, remove the fin and sand the
aft ends of the blocks flush with F-9B.
D 13. Use epoxy to glue the top plastic tail gear bushing,
centered on former F-9B just below the slot for the fin.
D 3. Tape the wing in position. Run a 1/4" drill bit through
the holes in the aft end of the wing to lightly mark the wing
bolt blocks. Do not drill the hole with the 1/4" bit. Remove
the wing and drill a 13/64" (or use a #10 drill bit) through
each of the wing mounting blocks. Angle the holes as
shown on the side view of the fuse plan. Cut threads in
each block with a 1/4-20 tap. Put a couple of drops of thin
CA on the threads and, after it has fully cured, run the tap
back through the holes to clean up the threads. Bolt the
wing to the fuse with two nylon 1/4-20 wing bolts and leave
it in place for the next few steps.
Mount The Wing To The Fuselage
D 1. Clean out the wing dowel hole in F-2 with a 1/4" drill
bit. Test fit the wing and adjust the dowel hole in F-2, if
needed, with a round file.
D 2. Seat the wing in the wing saddle and visually align it
with the fuse. Pin a string to the center of former F-10, then
extend it out to a wing tip. Put a piece of tape on the string
to mark the intersection of the string and the wing tip. Swing
the string over to the other tip and see if the distance is the
same (see diagram). Make slight adjustments to the angle
of the wing until the distance from the tail to the wing tips
is equal.
D 1. Draw an accurate centerline on the top of the stab,
perpendicular to the stabs TE.
D1 2. Center the stab on the stab saddle and pin it in
position. Study the aft end of the structure from 6-10 feet
back. If the stab tips are not equidistant above the wing,
carefully sand the high side of the stab saddle until the
stab is aligned.
