6.2.5.2 Nose Gear Doors
28.
‰
Locate the nose gear doors and test fit in
place. Sand any interference areas as
necessary.
Note: The gear in the down
position angle out approximately 110° from
the bottom of the fuselage.
‰
When satisfied with the fit of the doors, using
thick CA, glue the 2 hinges in place to the
fuselage.
Note: The nose doors angle
outward approximately 15° in the down
position.
‰
Cut approximately 2.5” from .025 wire. Bend
a 90° angle at one end leaving approximately
¼” at the base.
‰
Cut about ¼” from 1/16” brass tube and
place it over the .025 wire so that it sets at
the 90° bend. Glue in place with thin CA.
‰
Bend the long side of the .025 wire
approximately 60° in the perpendicular
direction to the 90° bend approximately 3/32”
above the brass tube.
‰
Twist the wire outward so that the 60° bend
angles outward approximately 15°.
‰
Glue the .025 wire spring into the wheel well
where the brass tube is glued to the rear face
of the retract plate.
Note: Once in place,
bend the wire as required to achieve the
correct gear door orientation. The door
should close and spring open.
‰
Repeat the above steps for the opposite side
door.
29. ‰
Cut two 3/8” square pieces of scrap 1/8”
balsa.
‰
Glue the balsa onto the interior of the gear
doors approximately mid door.
‰
Screw into each balsa part a #2x3/16” screw
with a washer. Do not fully tighten.
‰
Cut a 6” length of fishing line or similar string
and loop one end around one of the #2
screws and tighten the screw down.
‰
Loop the other end of the string onto the
other screw keeping some slack in the line.
‰
Test the actuation of the retracts and adjust
the length of string between the doors until
the doors fully close as desired.
