Great Planes Corsair 40 Kit - GPMA0177 - Manual (Page 8)

D 10. Test fit the joiner wire into both elevators. Make sure
that both elevators are flat on the work surface and that the
tips of the elevators align with the tips of the stab.
Lt 1. Locate the 1/8" die-cut ply (W02A) and the two 1/16"
die-cut birch ply (W02B) wing center spars. Use 30-
minute epoxy to glue the 1/16" die-cut birch ply center spar
to the front and back of the 1/8" die-cut ply center spar.
Make sure that all three center spars are perfectly
aligned. Wipe off any excess epoxy with alcohol and a
paper towel.
D 11. Draw a line 1" from the TE on both sides of the
elevators. Carefully sand a taper from this line to the TE.
Remove equal amounts of balsa from each side of the
elevator until the TE is 1/8" thick.
D 12. Taper the TE of the rudder using the same procedure
as used for the elevators.
D 2. Lay out the 3/32" die-cut wing ribs R-5 (W04) and the
1/8" die-cut wing ribs R-3 (W08) exactly as shown in the
photo. Position the 1/16" die-cut birch ply doublers R-3B
and R-5B (W01) on each rib as shown. By so doing we will
be making a right and a left pair. Use 30-minute epoxy to
glue the doublers to the ribs. Make sure that the doublers
are perfectly aligned with the ribs.
D 13. Sand the LE of the elevators and rudder to a "V"
shape as shown on the plans. Sand a radius on the LE and
tip ends of the stab and fin. Leave the TE of the stab and fin
squared off.
D 3. Locate the 1/8" die-cut ribs R-1 (W07) and the 1/8"
die-cut ply doublers R-1B (F01). Use 30-minute epoxy to
glue ribs R-1 together. Then, use epoxy to glue ribs R-1
between the rib doublers R-1B. Make sure that all four
pieces are perfectly aligned. Wipe off any excess epoxy
with alcohol and a paper towel.
