6. Position the control horn so the holes in the control horn align
with the hinge line. The pushrod will cause the control horn to fall
naturally on the elevator. Mark the location for the control horn
mounting screws on the elevator.
7. Move the control horn away from the elevator. Use a pin vise and
7/64-inch (2.5mm) drill bit to drill the holes for the control horn
mounting screws. Use care to drill the holes straight and parallel in
the elevator.
 Unlike the aileron control horns, the elevator control
horns use a backplate on the opposite side of the
control surface. Failure to fit this backplate will result
in control failure and possible loss of the model.
8. Use four 4-40 x 3/4 inch socket head cap screws to attach the
control horn to the elevator.
9. The socket head cap screws will thread into the control horn back
plate. Use a 3/32-inch hex wrench to tighten all four screws.
 Do not over-tighten the screws and damage the
underlying structure of the elevator.
10. When attaching the clevis to the servo arm, use the hole that is 5/8
in (16mm) from the center of the servo horn.

11. Attach a solder-type clevis to the elevator servo arm. Hold the
pushrod against the clevis. Use a felt-tipped pen to mark the edge of
the clevis on the pushrod.
12. Remove the pushrod from the fuselage. Remove the clevis from the
elevator servo arm. Cut the pushrod and solder the clevis on the
pushrod using the technique outlined for the aileron pushrods.
 Once the solder has cooled, pull hard on the pushrod wire
and clevis to make sure it has been soldered securely
in place. Failure to correctly solder the clevises can
result in pushrod failure and the loss of the model.
13. Reinstall the pushrod and connect it to the servo arm and control
horn. With the radio system on and elevator servo centered, adjust
the clevis to center the elevator. Use threadlock near the threaded
clevis, then tighten the nut against the clevis to secure the clevis.
Slide all retainers over the forks of the clevises to complete the
pushrod installation.
14. Install the remaining control horn on the opposite elevator.
