Install the Elevator & Rudder Pushrods & Servos
❏
1. Using the mounting grommets and eyelets supplied with
the servos, install the elevator and rudder servo into the fuse
with the servo output shafts toward the front of the fuselage
as shown. Drill a 1/16" [1.6mm] hole through each mounting
hole location. Secure them with the servo mounting screws
that came with the servos.
❏
2. Cut three arms from a four-armed servo arm for both
the rudder and elevator servo. Enlarge the third hole out from
the center of each remaining arm using a 5/64" [2mm] drill
bit. Use your radio system to center the servos and install the
servo arms perpendicular to the servo case as shown.
❏
3. Screw a nylon clevis with a silicone clevis retainer onto
the threaded end of each of the 36" [914.4mm] pushrods
until the threaded portion of the pushrod emerges from the
clevis as shown.
❏
4. Insert both of the 36" [914.4mm] pushrods through the
exit slots at the rear of the fuse. Connect both the elevator
and rudder pushrods to their control horns. Use the third-
from-the-inner hole in the control horn for both pushrods to
obtain the recommended throws. Slide the silicone clevis
keeper over the clevis.
❏
5. Position the rudder and elevator in the neutral position
and hold them in place with tape or small clamps. Mark on
the pushrods where the pushrods cross the outer holes in
the servo arms.
