1. We recommend that the receiver be installed behind

the servo tray. This will allow the motor battery to be moved
forward and aft to adjust the balance point (C.G.) later. Plug
the rudder and elevator servos, and the electronic speed
control into the receiver, with a 12" [305mm] servo lead
extension and a 12" [305mm] aileron servo lead extension.
The receiver can be secured to the bottom of the fuselage
with a 1" [25mm] piece of hook and loop material cut from
the second strip of material.

2. To secure the connection between the electronic

speed control lead and the servo extension, wrap a piece of
electrical tape or shrink tubing around the plugs. This can
then be attached to the inside of the fuselage with CA,
keeping it clear of the motor battery.

3. Plug the motor battery into the electronic speed

control. Switch on the transmitter, then the speed control.
Center the elevator and rudder servo trim on your
transmitter. If needed, remove the rudder and elevator servo
arms and center them.

4. Center the elevator and mark where the elevator

pushrod crosses the elevator servo arm. Make a 90° bend
at the mark. Cut the pushrod 3/8" [9.5mm] past the bend.
Attach the pushrod to the servo arm with a Faslink.

5. Trim a servo arm so that it has two arms, opposite

each other, with the outer holes approximately 7/16" [11mm]
from the center.

6. Install a screw-lock pushrod connector in both of the

holes 7/16" [11mm] from the center. Use the screw-lock
pushrod connector to secure them to the servo arm. Center
the servo arm on the rudder servo.

7. Insert the pull-pull cables through the screw-lock

pushrod connectors. Check that the cables are not twisted
inside the fuselage.

8. With the rudder centered, secure the cables in the

screw-lock pushrod connectors with 4-40 x 1/4" socket head
cap screws. The cables should be tight, but not so tight that
they put a strain on the servo. Cut off the excess cable.

9. Install the aileron servo in the aileron tray. Install a

servo horn with two arms and holes 7/16" [11mm] from the
center of the arm.
