6. Secure the air valve in the fuselage. Use a 14mm wrench to tighten
the nut, securing the valve in place.
7. Prepare the holes in the fuselage for the retract valve servo by
threading a screw into each hole. Remove the screws and place 2
to 3 drops of thin CA in each hole to harden the surrounding wood.
Once the CA has fully cured, install the retract valve servo with the
servo shaft toward the rear of the fuselage.
8. Insert the Z-bend of the retract valve pushrod through the hole in the
actuator.
9. Mount the servo connector in the servo arm so it is 11/32-inch
(9mm) from the center of the servo arm. Place a drop of canopy glue
on the M2 nut, then install it on the underside of the arm to secure
the connector. Set the throws for the retract servo to 0% in both
directions. Center the actuator as close to center as possible, then
tighten the setscrew securing the pushrod in the connector.
 It does not require much throw to operate the valve. Make sure
not to damage the valve using too much throw at the servo.
10. Slowly increase the servo throw at the radio system to move the
actuator into the valve. Make sure not to bottom out the actuator and
damage the valve.

11. Toggle the switch at the radio and slowly increase the throw until
the edge of the actuator is fl ush with the edge of the valve body.
 Make sure not to pull the actuator out of the
valve body and damage the O-rings.
12. Connect a Y fi tting to the tube from the center of the valve. Fully
press the air line into the fi tting.
 The air lines can be removed by pressing the shoulder against
the body of the fitting and pulling the air lines free.
13. Cut a 2-inch (51mm) piece of air line and connect the fi ll valve. The
arrow will point to the fi tting/valve. Attach the line from the air tank
to the fi tting.
 The arrow indicates the flow of air from the external fill pump into
the retract system. There is a check valve inside the valve that
stops air from flowing the other way and emptying the air tank.
14. Connect the remaining Y fi ttings for the up and down air lines. Use
air line colors that match those from the valve to differentiate the
operation of the retracts. Route the air lines in the fuselage along
the edges of the radio tray toward the openings for the wing. Secure
all the air lines and fi ttings in the fuselage. Add fi ttings at the ends
of the air lines to connect the air lines from the retracts in the wing
panels.
 With the push-in type pneumatic connectors it is important to
make sure the air line is pushed all the way into the air connectors
to seal the air lines. Failure to do so will result in air leaks.
