9. Use the pin-and-string technique to align the stab (this
time the T-pin will be stuck into the sheeting over the top,
middle stringer in the front of the fuselage). Once the stab has
been centered stick another T-pin into the rear of the stab.
❏
10. Cut a hinge block for the tail gear from leftover 1/4"
x 1/2" [6.4 x 13mm] balsa and glue it into position.
❏
11. Cut two 6-1/4" tail fillet blocks from the 3/4" x 1-1/4"
x 18" [19 x 32 x 460mm] balsa block.
❏
12. Remove the stab from the fuselage. Using a piece of
leftover 1/4" x 1-1/2" [6.4 x 38mm] balsa as a fin spacer,
place the fillet blocks on the fuselage with the spacer in
between (where the fin would be). Center the rear of the
spacer between the fuselage sides and center the front on
the top, middle stringer. Use a straightedge to make sure the
spacer is centered. Hold the spacer in place with a T-pin in
the front and the back.
❏
13. Glue the tail fillet blocks to the fuselage, but not to
the spacer.
❏
14. Remove the spacer without disturbing the tail fillet
blocks. Shape the spacer as shown on the fin spacer
