Assembly
1. Using a hobby knife, carefully remove any body tube
material that may still be attached to the pre-cut slots in the
body tube.
2. Insert the loose end of the shock cord and then the motor
tube assembly into the back of the rocket body tube as
shown. Position the motor tube assembly so that the fin
locks are located under and visible through the body
tube's pre-cut fin slots.
3. Apply cement along the full length of the fin root of a fin
(area of the fin that makes contact with the outside surface
of the body tube). Carefully insert the fin through a slot in
the body tube and snap the fin into place. Repeat this
process for the other two fins. (NOTE: Each fin should be

Cord
1. Screw the other screw eye all the way into the hole in the
bulkhead (3/32"/2.4 mm thick). Apply a bead of cement
where the screw eye meets the bulkhead.
2. Pass the free end of the shock cord through the coupler tube
(6"/15 cm long) and securely tie it to the screw eye attached
to the bulkhead with a square knot. (CAUTION: Do not put
cement on the knot or the shock cord. Cement will weaken
the shock cord.)
3. Cement the bulkhead to the end of the coupler tube.

4. Through the back end of the body tube, apply cement
where the fin tabs meet the motor tube, fin locks, front
AERO-FIBRE™centering ring and body tube. Through
the front end of the body tube, apply cement where the
baffle assembly centering ring meets the inside surface of
the body tube.
5. Lightly sand the surface of the lower body tube around the
launch lug slots. Apply cement to the base of a launch lug.
With the sloping portion of the launch lug toward the front
of the lower body tube, insert the tab on the bottom of the
lug into one of the pre-cut launch lug slots in the body tube.
Repeat this process for the other launch lug.
Upper
Body Tube
4. Make a pencil mark 3" (76 mm) from an end of the coupler
tube using the location guide. Lightly sand the surface of
the tube between the mark and the bulkhead. Use a small
dowel to apply a bead of cement around the inside of the
upper body tube about 1" (25 mm) from the end of the tube.
Then slide the coupler tube into the upper body tube up to
the pencil mark on the coupler tube.
5. Cement the nose cone into the forward end of the upper
body tube.
