INSTALL THE RADIO SYSTEM
1. Locate three 2 x 685mm [27”] pushrod wires
threaded on one end. Screw a nylon clevis onto the
threaded end of the wires 20 full turns. Install a
silicone clevis keeper onto the clevises. Connect a
nylon control horn onto each of the two clevises.
Install the clevis in the second hole from the end of
the control horn.
❏
2. Slide two of the wires with clevises attached
into the openings shown in the photographs.
❏
3. Position the control horns on the elevators,
positioning them the same way as you did with the
ailerons. Mark the location for the screw holes. Drill
through the marks you made with a 1/16” [1.6mm]
drill bit, drilling through the elevator. Secure the
control horn to the aileron with two 2 x 15mm [5/8”]
machine screws and the nylon mounting plate.
❏
4. Insert the third rod into the remaining opening on
the left side of the fuselage. Connect the control horn to
the clevis and attach the control horn to the rudder in
the same way you installed them to the elevators.
❏
5. Install the rudder servo into the servo tray at the
position shown. Mark the location for the servo
mounting screws. Drill a 1/16” [1.6mm] hole through
the marks, drilling through the plywood tray. Insert and
then remove one of the servo mounting screws supplied
with your radio into each of the four holes you have
drilled. Apply a couple of drops of thin CA to each of
the holes to harden the threads. After the glue has cured
permanently mount the servo.
❏
6. Be sure the rudder servo is centered. Enlarge
the outermost hole in the servo arm with a Hobbico
Servo Horn Drill (or a #48 or 5/64” [2mm] drill bit).
