28. Use a sanding block to sand the top of the aft
deck sheeting down to the height of the former tops.
❏
29. Place the 1/2" x 2" x 17-7/8" top deck block
on top of the fuse. Trace the shape of the fuse
onto the bottom of the block. Roughly cut the block
to shape.
❏
30. Mark a 1/2" wide slot on the top deck block
that will allow the fin to protrude through. Notice
that the fin LE sweeps back. Cut the slot into the
deck block. Temporarily plug the fin into the slots in
formers F-9 and F-10. Adjust the slot in the deck
block if necessary for a satisfactory fit. Tack glue
the deck block to the fuse but
do not glue the fin.
Remove the fin and thoroughly glue the deck block
to the fuse with thin CA.
❏
31. Shape the deck block to match the cross-
section on the plan. A razor plane is helpful for this
kind of shaping.
❏
32. Remove the fuselage from the building board.
❏
33. Inspect the structure from the inside. Add
glue to any open joints.

1. Cut two of the 24" outer pushrod guide
tubes to the lengths required for the rudder and
elevator pushrods (see fuse side view).
❏
2. Roughen the outside of the pushrod tubes
with sandpaper. Slide the tubes through the 3/16"
holes in the formers with reference to the plan.
Securely glue the tubes to all formers they contact.
❏
3. Cut 10" off the unthreaded end of a threaded
pushrod wire . Cut about eight 5/16" lengths of the
inner pushrod tube from the material left over from
the inner aileron pushrod. Use rubbing alcohol to
remove any residue from the pushrod wire. Slide the
short lengths of inner tube over the pushrod wire,
spacing them approximately 3" apart. These act as
spacers to support the wire pushrod in the guide tube.
The spacers can be shorter than 5/16" if they are to
hard to push on.
The spacers must not be near the
end of the outer pushrod tube . Apply a small drop
of thin CA to each spacer if the fit is loose.

4. Screw the nylon double-ended ball link onto
the threaded end of the .074" x 24" wire. Make a
