1. Install the servos in the tray with the elevator
servo all the way against the right side of the plane.
For maximum throw you will need longer arms than
come with the radio. Dubro heavy duty horns work
fine. The long elevator horn is 1-3/8” long. The double
ended horn for the rudder is 2.305” long. Install the
elevator horn, then mount the rudder servo with the
horn installed so it will clear the elevator arm. This will
put it a little left of center. The throttle servo can then
be mounted on the left side of the plane. (Note: This
set up was for a four stroke engine. If you use a
different engine you may have to mount the ser-
vos differently). Mount the throttle servo so it is on
the same side as the arm on your engine. It does not
matter if the elevator servo is on the right or left.
2. Install the throttle EZ connector in one of the
arms that came with your servo.
3. Install a golden clevis on the end of the 2-56
x 20 pushrod. Insert the pushrod in the hole in
firewall that you drilled earlier. Slip the 5/32”
nylon tube over pushrod and cut to length. It
should extend out the hole in the firewall
about 1/4” and stop short of the servo by
about 2”. Connect the clevis to your engine
and insert the pushrod in the connector body.
4. Glue the nylon tube in the hole where it exits
the firewall.
Adjust the throw on the servos after the radio
is installed.
1. Insert the cable through the 1/16 OD x 1/4”
brass tubing.
Next thread the cable though the hole at the
end of the 2-56 threaded rods and loop it back
through the brass tube.

2. Loop the end of the cable back though the
brass tube.
Crimp the brass tube with pliers.
