Stand back 15 to 20ft [5 to 6m] and check to be sure
the stab is parallel to the wing. If necessary, adjust
the stab saddle as needed by lightly sanding it until
the stab and wing are parallel.

o 2. Remove the stab from the fuselage. Place the
elevator joiner rod into the half-circle notches at
the aft end of the stab saddle in the fuselage with
the control horn pointing down. Mix up a batch of
30-minute epoxy and coat the top and bottom of
the stab where it will contact the stab saddle in the
fuselage. Slide the stab into position in front of the
elevator joiner rod. Center the stab left and right in
the fuselage and measure the distance from the tip
of each wing to the tips of the stab. Adjust the stab
until the distance from the tip of the stab to the tip of
the wing is equal on both sides. When satisfied, wipe
away excess epoxy with denatured alcohol, confirm
that you have not glued the elevator joiner wire to the
stab, and let the epoxy cure undisturbed.
o 3. Fit a CA hinge into each hinge slot in the stab.
If the hinges are difficult to install, use a hobby knife
to slightly enlarge the slots. Roughen the ends of the
elevator joiner wire and clean them with alcohol. Test
fit the elevators to the hinges in the stab and joiner
wire. The joiner wire ends fit into the holes at the TE
of both elevator halves. Look at the elevator halves
from behind and confirm that they are parallel. If not,
remove the elevators and gently bend the joiner wire
as necessary. When satisfied, apply a light coating
of epoxy to the ends of the joiner wire and join the
elevators to the stab with the hinges. Be sure that the
elevators are evenly spaced from the fuselage. Wipe
away any excess epoxy from around the joiner wire.
Remove the pins from the hinges and position the
elevators against the TE of the stab. The hinge gap
between the elevators and stab should only be wide
enough to allow a small line of light through. When
satisfied, apply 6 drops of thin CA glue to the center
of each hinge on both sides. When the CA has dried,
gently pull on the elevators to confirm that they are
securely glued in place.
o 4. Roughen the plastic tube on the rudder
steering rod with 220-grit sandpaper. Install a nylon
torque rod horn onto the threaded end of the rudder
steering rod.
