Hook Up the Elevator & Rudder
❏
1. Test fi t the “Z-bend” of one of the two longest wire
pushrods into the outer hole of one of the fi berglass control
horns as shown in the photo. If necessary, spin the horn
around the wire a few times to loosen the hole in the horn so
the pushrod will move freely.
❏
2. With the horn attached to the pushrod, slide the pushrod
into the rudder guide tube in the fuselage. Fit the horn into the
slot in the rudder. Use a few drops of thin CA followed by a few
drops of medium CA to securely glue the horn into position.
❏
3. Connect the elevator pushrod the same way.

4. Temporarily connect the servos you will be using for the
elevator and rudder to your receiver with a receiver battery,
or with your ESC and the motor battery, so you can operate
the servos with the transmitter. Center the trims on your
transmitter and turn on the transmitter and receiver. Position
the servo arm on each servo so the longer arms will be
perpendicular to the servos.
❏
5. Use a #56 (.046" [1.2mm]) drill or a hobby knife to
enlarge the holes in the servo arms for the screw-lock pushrod
connectors. Mount the screw-lock pushrod connectors to the
servo arms with the nylon retainers.
Refer to this photo for the next four steps.

6. Test fi t the elevator and rudder servos in the servo rails
in the fuselage. If the rails are too far apart for the servos you
