Note:
If the silicone retainer on the clevis rubs against the inside
of the fuselage sides, use a hobby knife to trim the inside of the
fuselage as necessary for free, smooth movement.
❍
4. Install the rudder pushrod and mount the control horn
the same way.
❍
5. Without using any glue, install both hardwood servo
rails into the slots. Glue the forward rail into the fuselage as
far forward as it will go.
Refer to this photo for the following four steps.
❍
6. Position the servos on the rails and slide them forward
against the forward rail. Note the position of the splined
output shaft on the servos (the elevator servo is facing aft
and the rudder servo is facing forward). Space the rail
approximately 3/32" [3mm] aft of the servos, and then
securely glue the rail into position.
❍
7. Place the servo arms on the servos–if your servos
came with a selection of servo arms, select ones that will
not interfere with the other servo or the fuselage sides. For
Futaba
®
and Tower servos, use the six-arm servo arms and
cut off the unused arms.
❍
8. Position the left servo all the way over to the
left
side
of the fuselage, then drill 1/16" [1.6mm] holes through the
rails for the servo mounting screws. Mount the servo with
the screws that came with it.
❍
9. Move the rudder servo as far over to the
right
as it will
go
without the arm contacting the right fuselage side.
Drill 1/16" [1.6mm] holes through the rails and mount the
rudder servo with the screws that came with the servo.
❍
10. Center the servo arms as shown holding the elevator
pushrod so the elevator is centered. Mark the pushrod where it
crosses the holes in the elevator servo arm.
❍
11. Use pliers to make a 90° bend in the pushrod at the
mark you made.
❍
12. Take the servo arm off the servo. Enlarge the holes in
the servo arms with a servo horn drill (HCAR0698), a 5/64"
[2mm] drill bit or a hobby knife. Connect the pushrod to the
outer hole in the elevator servo using a 90° pushrod
connector. Cut the pushrod 1/16" [1.6mm] from the connector.
Then replace the servo arm on the servo.
❍
13. Connect the rudder pushrod to the rudder servo the
same way.
