STEP 4: INSTALLING THE AIR TANK AND FILL VALVE
❑ Install the air tank into the back of the center fuselage pod, using the
plywood support provided.
❑ Install the ll valve onto the fuselage side, making sure to tighten the
mounting nuts securely.
❑ Connect the air lines from the retracts, air tank and ll valve to the
air control valve, using the diagram at left. Use quick-connectors on the
air lines to make it easy to connect the air lines when assembling the
airplane.
OPTIONAL LANDING GEAR DOOR INSTALLATION
STEP 1: HINGING THE MAIN LANDING GEAR DOORS
❑ Cut two notches 1/8" (3mm) wide on the hinge side of each main
landing gear door. Position one notch 1-3/4" (44mm) behind the front
edge of each landing gear door and one notch 2" (50mm) in front of the
rear edge of each landing gear door.
❑ Glue two hinges to each landing gear door, making sure that the
center of each hinge pivot point is centered with the edge of the landing
gear door.
❑ Glue one balsa block underneath each hinge mounting location on
the two fuselage booms.
❑ Drill a 1/8" diameter hole into the fuselage and through the balsa blocks
for the landing gear door hinges. Make sure to position the holes so that
the edge of each landing gear door is ush with the outside edge of the
fuselage booms. The holes will need to be right up against the edge of
the fuselage booms.
❑ Test-t and hinge the landing gear doors to the fuselage booms. When
aligned properly, the landing gear doors should be ush with the fuselage
booms when closed and they should pivot freely.
You may need to sand the outer edges of the doors
to prevent them from hitting each other when closed.
The air source is connected to the
middle nipple on the air control
valve.
The outer nipples on the air control
valve are for the UP and DOWN air
lines. It does not matter which one
is used for which purpose. The
only effect is that it changes which
position is up and which position is
down (which can be changed to the
pilot's preference by reversing the
retract switch on the transmitter).
The UP and DOWN air lines are
connected with "T" Fittings.
