❏
25. Position the retractable tail wheel on the
rails and mark the mounting hole locations. Drill
a 7/64" pilot hole at each mark. Attach the
retractable tail wheel to the rails with #6 x 1/2"
sheet metal screws. Check that the former does
not interfere with the movement of the retractable
tail wheel.
❏
26. Use 30-minute epoxy to glue former F-10 to
the fuse sides. It should be located using the
notches in the aft fuse doublers. Work a piece of
masking tape under the fuse and use it to pull the
fuse sides against the former. Make sure F-10 is
perpendicular to the building surface and the fuse
is aligned over the fuse plan. Use a couple of
T-pins to hold it in place.
❏
27. Use medium CA to glue former F-9 into
position over its location on the plan. Use the
same technique used with F-10 to hold the
fuse sides against the former. Make sure F-9 is
perpendicular to the building surface and the
embossed number is facing forward.
❏
28. Glue the die-cut 1/8" plywood tank tray
(TT) in front of F-9, over its location on the plan.
❏
29. Glue the unglued portion of former F-8 and
the aft end of the crutch to the fuse sides.
❏
30. Use medium CA to glue former F-11 into
position over its location on the plan. Use the
same technique used with F-10 to hold the fuse
sides against the former. Make sure F-11 is
perpendicular to the building surface and the
embossed number is facing forward.
❏
31. Carefully sand the outside of the three 36"
outer pushrod guide tubes with coarse
sandpaper so the glue will stick better.
❏
32. Insert one outer pushrod tube in the holes
for the rudder pushrod. Mark and cut out the
rudder pushrod exit where the tube contacts the
fuse sides.
❏
33. Approximately 1" of the rudder outer
pushrod tube should protrude past the exit hole in
the fuse side. Glue the outer pushrod tubes to the
formers with medium CA and to the exit slot with a
50/50 mixture of microballoons and epoxy.
❏
34. After the epoxy has cured, use your bar
sander to sand the pushrod guide tube and epoxy
filler flush with the fuse side.
