Great Planes Corsair 40 Kit - GPMA0177 - Manual (Page 29)

D 11. Now is a good time to apply balsa filler to any gaps in
joints. This will allow you to finish sand most of the fuse
before installing the fin and stab.
D 12. Trim the canopy with a scissors using the embossed
cut lines for reference.
D 13. The top deck sheeting overlaps the instrument panel
by 1/4". Use T-pins to locate the instrument panel and draw
a line 1/4" behind them. Cut the 1/2" turtle deck block flush
with former F-6B. Center the canopy over the cockpit and
mark the outline. Now, move the canopy approximately 1/4"
in the direction of where the cut will be made and mark the
outline again. By cutting the balsa on the inside line, a 1/4"
border will be left to mount the canopy.
D 1. Reinstall the wing on the fuse. Cut a notch for the
elevator joiner wire at the aft end of the slot for the stab.
Install the joiner wire in the notch. Then slide the stab into
the stab cradle. Check that the stab is still parallel to the
wing and that the stab tips are an equal distance from the
nose of the fuse. Lightly draw lines on the top and the
bottom of the stab at the joint between the stab and fuse.
Remove the stab and apply 30-minute epoxy to both sides
of the stab between the lines. Slide the stab into position
and check its alignment. Wipe off the excess epoxy with
alcohol and a paper towel and allow the epoxy to cure.
D 2. Position the fin in the slot in the turtle deck. Hold a
triangle on the stab and close to the fin. Check that the fin
is perpendicular to the stab. Glue the fin in the slot with
6-minute epoxy.
D 3. Test fit the elevators on the stabilizer and sand as
necessary to clear the fuse sides.
D 14. Now that the balsa filler has had a chance to dry,
finish sand the tail section area. Check all the joints around
the balsa blocks and sheeting. If any have come loose or
were missed during the building process, glue them before
finish sanding with 320-grit sandpaper.
Note: We recommend that the stab and fin be installed at
this point in the construction process. By installing them
now, a small fillet can be made at the joint between the
fuse, stab and fin. However, to make covering the fuse
easier, the stab and fin can be installed after everything
is covered.
D 4. Make sure that the tail gear moves freely while
applying upward pressure. Hold the rudder up to the fin and
mark the tail gear "arm" location on the rudder LE. Drill a
7/64" hole 7/8" deep at this spot.
