string and align the arrow with one end of the stab as shown
in the photo. Swing the string over to the same position on
the other end of the stab. While keeping the TE of the stab
centered in the fuse, adjust the stab and slide the tape along
the string until the arrow aligns with both sides of the stab.
Be certain the stab remains centered, side-to-side, during
this process.

6. Lightly mark the top and bottom of the stab along both
sides of the fuse, so you will be able to apply the covering
up to the line. The lines will serve as a guide for covering and
gluing in the stab when it's time.
❏
7. Place a straightedge across the top of the fuse over
former F3. View the fuse from about ten feet back and see if
the stab is parallel with the straightedge. If it is not, carefully
sand the fuse where the stab fits to get it parallel with the
straightedge.
❏
8. Fit the fin to the fuse. Position a 36" (or longer) straightedge
along the left side of the fin. Adjust the straightedge and the
fin so the front of the straightedge aligns with the mark you
made earlier that is 1/8" left of the centerline. Now the stab
is centered laterally. Hold it into position with T-pins.
❏
9. Use 30-minute epoxy to glue the fin to the fuse. Before
the epoxy hardens, use a builder's square to make certain
the fin is perpendicular to the stab. If necessary, use
masking tape to pull the tip of the fin to one side of the stab
or the other to get it vertical.

1. Glue both halves of the die-cut 1/8" balsa former F6-B
together. Glue former F6-B and the die-cut 1/8" balsa former
F7-A into position on the fuse top.
❏
2. Glue a leftover 1/4" x 5/8" balsa stick to the fuse top
between the two notches for the aft wing struts. Glue both
halves of the die-cut 3/32" balsa cockpit floor together.
Glue the cockpit floor and the die-cut 1/8" balsa former F4-A
into position.
