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). Center the rudder and
align the wire pushrod with the hole in the end of the servo
arm. Use a fine-point felt-tip pen to mark the wire where it
crosses the holes in the servo arm. On that mark make a 90
degree bend. From the bend measure an additional 3/16"
[4.8mm]. Then cut off the excess pushrod wire. Install a
nylon Faslink to the wire and servo arm.
❏
7. Install the elevator servo into the servo tray. Position it
in line with the elevator pushrods. Mount the servo using the
same procedure used for the rudder servo.
❏
8. Make a bend in one of the elevator pushrod wires
as shown.
❏
9. Screw a 6-32 x 1/4" [6mm] socket head cap screw with
a small amount of threadlocker into two 5/32" [4mm] wheel
collars. Slide the wheel collars onto the wires. Align the
elevators. Tighten the set screws against the wires. Cut the
excess wire.
❏
10. Be sure the elevator servo is centered. Enlarge the
first hole in the servo arm with a Hobbico Servo Horn Drill
(or a #48 or 5/64" [2mm] drill bit). Center the elevators and
align the wire pushrod with the hole in the end of the servo
arm. Using a marker, mark the location where the wire
aligns with the hole in the servo arm. On that mark make a
90 degree bend. From the bend measure an additional
3/16" [4.8mm] and then cut off the excess pushrod wire.
Install a nylon Faslink to the wire and servo arm.
