Horizontal stabilizer
and elevator:
As you did for the wings, glue
cap strips onto the eight hori-
zontal stabilizer ribs
(CAW09). Drill #75 holes in
CAW33 where indicated on
Plan 03.4 for stringing the
cross bracing rigging.
Referring to Plan 03.4, use
3/32" square lumber to make
the stabilizer spar. File a
rounded notch in each end
for a tight fit to the stabilizer
casting (CAW33). String the
ribs onto the spar, then posi-
tion the ribs and spar within
the casting and glue every-
thing in place. Attach the six
nose ribs.
Cut the stabilizer compres-
sion bars from 3/32" square
lumber, notch the ends for
the cross bracing rigging ends
and glue into place. Using
turnbuckles (W042), where
indicated in the drawing, rig
the cross bracing (WP1205)
in the same manner you
chose for the wings.
Glue on the two elevator
horns (CAW35) where indi-
cated in Fig.14, making sure
that the ends angle forward.
Referring to Fig.15, attach
the elevator to the stabilizer
by crimping four CAW32
hinges over the notched areas.
DO NOT USE GLUE.

Vertical stabilizer and rudder:
The vertical stabilizer (CAW36) and rudder
(CAW37) are complete castings except for the rud-
der horn (CAW35) which must be glued in place
with the angled horns facing forward. You will need
to drill a #75 hole through the top of the front ver-
tical brace in the rudder (Fig.14) to accept rigging
when the empennage is attached to the fuselage.
Attach the rudder to the vertical stabilizer by
crimping three CAW32 hinges as indicated. DO
NOT USE GLUE.
