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.
