5. Install the air valve servo using the hardware that
came with the servo. Enlarge the outer hole of a short
servo arm with a 5/64" [2mm] drill.
❏
6. Install a plastic ball link onto the threaded end of
a 2-56 x 6" [152 mm] pushrod wire. Put the ball link on
the ball. Pull the air valve cylinder towards the front of
the fuselage. Position the servo arm slightly towards the
front of the fuselage. Make a mark on the wire where
it aligns over the hole enlarged in the servo arm. Bend
the wire on that mark. Cut the wire 3/8" [10 mm] above
the bend in the wire. Install the wire in the hole you
drilled in the servo arm and secure it to the servo with
a nylon Faslink.

7. Enclosed with the kit is the 1/8" [3mm] plywood
plate you see in this photo. This is a backing plate for
the air fi ll valve. Choose a location you wish to mount
your fi ll valve. We chose the fuselage side. Glue the
plywood plate to the fuselage. Open the hole through
the plate and into fuselage side for the fi ll valve.

8. Install the air fi ll valve into the former extending
outside of the fuselage.

9. Connect the air lines to the air valve, fi ll valve and
air tank following the instructions that came with the
retract system. Secure the air tank into the former in
the back of the fuselage with Shoe Goo or silicone glue.
Leave the fuselage undisturbed until the glue cures.
