or Great Planes Plan Protector.

the fuse plan.
❏ 3. From one of the 3/16" x 3/8" x 30" balsa sticks, cut and
glue the fin frame together. Note that there are two pieces
along the bottom of the fin and that the TE ends at the
bottom of the stabilizer.

fin cross braces to the frame.

thin CA.

the glue joints and add CA to any joints that don't look strong.
