installing the recommended Tactic servo, drill the holes with
a 1/16" [1.6mm] drill bit. Threading a servo mounting screw
into each hole and then removing it, followed by a drop of
thin CA in the hole, will harden the surrounding wood for a
very secure servo installation. When the CA glue is dry, install
the servo with the screws included with the servo.

11. Use a small clamp or tape to hold the rudder in the
neutral position. Mark the pushrod where it crosses the hole
in the servo arm. Temporarily disconnect the clevis from the
control horn, turn the pushrod sideways and make a 90 degree
bend at your mark. Cut off the excess pushrod 1/4" [6mm]
beyond the bend. Fit the bent end of the pushrod wire into
the servo arm hole and secure it with a 90 degree pushrod
connector. Reinstall the clevis into the second outer hole in
the rudder control horn. Slide the silicone clevis retainer up
to the end of the clevis and you can now remove the clamp
or tape holding the rudder centered.

12. The elevator pushrod should be installed into the hole
in the servo arm closest to 13/32" [10.3mm] from the center
of the servo arm. Install the elevator servo and pushrod and
elevator control horn in the same manner that you did the
rudder servo.

13. Apply a couple drops of CA glue to the tail skid barbs
before you press it into place to secure it.
