2. Position the control horn on the elevator at the hinge line
using the same technique used on the ailerons. Drill a 1/16"
[1.6mm] hole through the mounting holes in the control horn,
drilling through the elevator. Insert a 5/64" x 9/16" [2x14mm]
machine screw through the control horn and the aileron.
Secure the horn by threading the screws into the nylon back
plate, tightening it to the aileron.

3. Repeat step 2 for the remaining elevator half and
the rudder.

4. Install the elevator and rudder servos into the servo tray
in the direction shown using the hardware supplied with the
servos. Be sure to harden the screw holes with thin CA as
was done with the aileron servos. Cut three arms from two
four-armed servo arms. Center the servos with your radio
system and install them onto the servos, perpendicular to the
servo case with the servo screws. Enlarge the outer holes of
each servo arm with a 5/64" [2mm] drill bit.
Pushrod Wire

5. Center the rudder, then make a mark on the pushrod
wire where it aligns with the outer hole in the servo arm. Make
a 90 degree bend at the mark and cut off the excess pushrod
1/4" [6mm] beyond the bend. Secure the pushrod to the servo
arm with a nylon FasLink. Make any adjustments necessary
to the nylon clevis so that the rudder is properly centered,
then slide the silicone clevis retainer to the end of the clevis.
