in the fuselage former as shown. Mark the pushrod
where it crosses the outer hole of the servo arm.

a 90° bend at your mark. Cut off the excess pushrod
1/4" [6mm] beyond the bend. Reinstall the mount into
the fuse and glue it into the slots. Connect the pushrod
to the servo arm and secure it with a FasLink.

7. Reference the photos for installing the air lines
and T-fi ttings. Drill a hole for the air fi ll valve on the
side of the fuselage. Be sure to use threadlocking
compound on the thumb nuts. The pressure gauge
should be mounted to the cockpit fl oor so it can be
seen through the canopy. Install quick disconnects
onto the air lines that connect to the retracts.

8. Adjust the ATV on your radio so that the retract
servo only travels the short distance needed to open
and close the retract valve.

valve by joining the quick disconnects. Fill the air tank
by connecting a pump to the fi ll valve and fi ll the tank
to 100 psi.
❏
10. Test the operation of the retracts using your
radio system. The adjustment screws on the valve
control how quickly the retracts raise and lower.
