Connect the servo to a receiver and power supply. Turn
on your transmitter. Set trim and sub trim to zero. Install
a servo arm on the servo about perpendicular to the
servo's side. Use the transmitter's sub trim to make it
exactly perpendicular to the side of the servo.
Attach an 18" servo extension onto the elevator servo
lead and use a safety clip to secure the connection.
Insert a servo into the elevator servo pocket with the
drive spline towards the front of the fuselage. Pre-drill
for the servo mounting screws using a 1/16" drill.
Remove the servo and apply a drop of thin CA glue into
each mounting screw hole. This will harden the wood
around the screws and provide a more secure
installation. Allow the CA glue to dry before reinstalling
the servo.
Assemble a ball link to each end of a connecting rod. Use
a socket head screw, a flat washer and a nylon lock nut to
connect a ball link to the servo control horn.
Adjust the length of the connecting rod to the servo arm
with the elevator aligned with the stabilizer. When the
correct length of the assembly is found, connect the ball
link to the elevator control arm on the inside as shown.
(Always adjust the connecting rod length with the servo
powered up and centered.)
Rudder
The rudder control can be configured as a push-pull or as
a pull-pull cable system.
The pull-pull control horn is located approximately 2 7/8"
from the bottom of the rudder.
The push-pull control horn is located approximately 9/16"
from the bottom of the rudder.
