INSTALLING THE AILERON SERVO.

Install the aileron servo into the servo
mount, with the output shaft towards the lead-
ing edge of the wing, using the wood screws
provided with your radio system. Drill 1/16"
pilot holes through the mount before installing
the screws. This will prevent the wood from
splitting.

INSTALLING THE AILERON LINKAGE.

1) Thread one nylon adjustable control
horn onto each aileron torque rod. Thread the
horns on until they are flush with the ends of
the torque rods.
2) Thread one nylon clevis at least 5/16"
onto each of the two threaded wires.
3) With the aileron servo centered, install
the servo arm onto the servo. The arm should
be installed so it is parallel with the trailing edge
of the wing.

off the rear portion of one of the 3 nylon tubes

stopper. This will be the fuel pick up tube.
2) Using a modeling knife, cut one length
of silicon fuel line. Connect one end of the line
to the weighted fuel pick up and the other end
to the nylon pick up tube.
3) Carefully bend the second nylon tube
