29. Mark a 3/16" x 3/16" x 3/16" [4.8mm x 4.8mm
x 4.8mm] square centered on the fuselage, centered
on the position the wire goes through the nylon
mounting bracket.
❏ ❏
30. Use a rotary tool or file to cut the marked
portion away. Slide the wire through the nylon mount,
into a 1/16" [1.6mm] wheel collar. Install and tighten
a 4-40 set screw against the wire.
❏ ❏
31. Drill a 3/32" [2.4mm] hole through each of
the mounting holes in the nylon control horn, drilling
through the landing gear door. Insert a 2-56 x 3/8"
[9.5mm] screw into each of the holes and secure
them to the door with a 2-56 nut. Be sure to apply a
drop of thread locker to the screw.
❏ ❏
32. Manually move the landing gear in and out
of the wheel well a few times. When you are satisfied
that everything is working well, go through the
completed door installation and apply a drop of
thread locker to each of the nuts and bolts. As
mentioned earlier the bolt that goes into the nylon
collar should not be over tightened. The collar should
be able to move on the back strut. Instead of thread
locker, use a drop of aliphatic glue on the threads of
the bolt going into the nylon collar. While going
through all of your installation, remove the axle from
the landing gear and slide two #8 flat washers onto
the axle on both sides of the wheel to keep it
centered in the landing gear. Be sure to use thread
locker on the axle screws during the final installation.
❏
33. Repeat steps 1-29 for the other landing gear.
Note: When you have completed the installation of the
gear you might wish to apply a bit of deep red paint to
the heads of the screws you installed in the door.
Retractable Tail Wheel
Installation of the retractable landing gear for the
main landing gear does not require that you use a
retractable landing gear for the tail wheel. Some
versions of the Staggerwing that have been restored
have not always utilized a retractable tail wheel. If
you wish to use a fixed tail wheel go back to page 17
for the instructions on its installation. If you use the
retractable tail wheel it will require the use of one
additional 90 oz-in servo (the Futaba S3305
[FUTM0035] is an inexpensive servo suitable for
this), pushrod wire and the Robart #121 scale retract
tail wheel (ROBQ2210).
❏
1. Cut off the mounting lugs from the Robart tail
wheel retract unit as shown.
