33. D GLUE ON THE 1/4" x 1/4" BALSA TOP STRINGER

Cut to length and glue the 1/4" x 1/4" balsa stringer

in place between formers 3A/3B and 6A/6B.

34, D ADD FORMERS 4A AND 5A

Locate the positions of formers 4A and 5A by

placing a straight edge along the top stringer. Place and
glue the formers so they mate with the stringer and are

centered from side to side.

35. D ADD THE 1/8" x 1/4" STRINGERS

Add the 1/8" x 1/4" balsa stringers by gluing them

at 6A/6B first, checking with a straight edge and then gluing
to 5A, 4A and 3A/3B.

36. D PREPARE AND GLUE IN THE SIDE NOSE

BLOCKS; FINAL SAND THE FUSE FRONT

Groove the inside of the nose side block (right or

left depending on your engine) for the throttle linkage
clearance. Using 5 minute epoxy, glue the nose side
blocks in place. Remove excess epoxy at the chin block

joint. Carve and rough sand the hood top, hood sides and

chin block to the shape of the nose side pieces.
