❏ 6. Pull the tail posts together and use a bar sander to
lightly sand the inside edges of the tail posts to an angle.
Align the fuse over the fuselage top view, checking the tail
posts for the proper width. Carefully line up the tail post and
glue them together. Note: A small misalignment here will
throw the aft end out of line, so double-check before gluing.
❏ 7. Test fit the die-cut 1/16" balsa aft deck base between
the forward center fuse sides and the stab saddle. Trim the
aft end of the deck base for a good fit.
❏ 8. Pin the aft deck base to the plan top view (note that the
front of the deck base is flush with the front of F-3). Use the
former locator marks and draw the former location lines on
the aft deck base.
❏ 9. Trial fit former F-4 between the longerons at the former
location lines (the cross braces face aft). Note that the sides
of F-4 and the cross braces will have to be sanded to a
slight taper to make good contact with the longerons.
Remove F-4 and sand as required for a good fit. Do not glue
F-4 to the longerons.
10. Repeat the above process to properly taper the sides of
F-5 and F-6.
❏ 11. Position F-4 between the former location lines on the
aft deck base. Adjust the position of F-4 so it is centered
between the edges of the aft deck base. Glue F-4 to the aft
deck base, perpendicular to the aft deck base.
❏ 12. Repeat the procedure, gluing F-5 and F-6 to the aft
deck base. Remove the deck base from the plan.
❏ 13. Pin the fuselage over the plan top view. Make sure
former F-3 and the tail post are aligned with the plan. Check
that the sides of the tail posts are perpendicular to the
building board.
