Reinforce the pilot holes for mounting the
actuator valve (pre-drilled in the bulkhead) with
some thin CA adhesive.

bulkhead to ensure a firm attachment.

Temporarily place the servo arm on the servo
and test the motion using your radio retract
switch, this will give you an idea of the best
servo arm geometry and length.
}}}}
Measure the distance between the actuator
valve and the servo arm and bend a control rod
to shape.

}}}}
Install the control rod and servo arm and test
the motion of the actuator valve with your radio.
Make any necessary adjustments to the control
rod length and servo arm position. Once you are
happy with the operation attach the servo arm
to the servo using the screw supplied with the
servo.

Tip: the air tank for the retracts can be mounted
in other locations of the fuselage. Locations
such as farther up in the cockpit or to one side
of the thrust tube can be used. If you would like
to do this just plan your air line runs
accordingly.
