❏
18. Position the tail block between the upper
fuse sides 4" aft of former 6. Make sure the notch
in the tail block is on the left side and glue it
in place.
❏
1. Cut the outer guide tube from a Great Planes
24" Flexible Cable Pushrod (not included with this kit,
GPMQ3700) to a length of 17" to be used for the
elevator. Roughen the outside of the guide tube with
sandpaper so glue will stick. Slide the pushrod
through the bottom holes in formers 3 through 6 as
shown in the side view of the fuse plan.
❏
2. Roughen the outer guide tube from an
additional Great Planes 24" Flexible Cable
Pushrod kit and slide it through the holes in the
sides of formers 2 through 6. This is the antenna
guide tube.
❏
3. Glue both guide tubes in position with medium CA.
❏
4. Use a straightedge and a ballpoint pen to mark
the front edge of former 3 on both upper fuse sides.
❏
5. Use a razor plane and/or a bar sander and
80-grit sandpaper to sand the top edge of the
upper fuse sides as shown in the cross section
drawings on the plan. The top edges of the upper
fuse sides must be even with the tops of the
formers to accommodate the fuse top.
❏
6. Glue the 1/8" x 1-1/4" x 30" balsa fuse top to
the fuse with medium or thick CA. The aft edge of
the fuse top should extend 1/2" aft of former 6.
❏
7. Use a hemostat or small needle nose pliers
to remove the T-pins from the fuse bottom that are
holding it to your building board. You should be
able to reach the T-pins through the space
between the upper fuse sides and the fuse bottom.
Remove the fuse from your building board.
❏
8. Trim the edges of the upper fuse sides and the
fuse bottom even with the formers to accommodate
the lower fuse sides, the same way you did for the
fuse top.
❏
9. Glue one, then the other die-cut 1/8" balsa
lower fuse side to the fuse. Handle the fuse
carefully as you position so you do not build in any
twist to the fuselage.
❏
10. Use your razor plane and/or your bar
sander to sand the lower fuse sides even with the
upper fuse sides and the fuse bottom. Trim all
sheeting even with the tail block.
