Modified the Disposable Rocket (i.e, firework / fire hazard) into a REUSABLE rocket.

The original files (nosecone B, fin B) wouldn't fit into my 18mm engine no matter how much i pushed, so they were enlarged a few tenths of mm.

Added a payload module that holds a streamer. Added a loop on the fins for securing the rubber band. Added a bar across the nosecone to secure the other end of the rubber band.

Needed: 1 large, or 2 smaller rubber bands About 10" x 1/2 or 5/8" crepe paper or mylar (I'm using a strip of mylar from one of those space blankets) for a streamer. 2-3 pieces of model rocket recovery wadding

Assembly (see photos): Cut the rubber band(s). Tie 2 together if using one any smaller than the length of the finished rocket. Push rubber band through the small loop on the fins and tie a knot on the end; or just tie it to the loop. Insert rubber band into the hole on payload section from outside to inside. Tie the streamer onto the rubber band about 2 inches from the end. Use the remaining inch or so of rubber band to tie to the bar on the nose cone.

FOLD up the streamer (try not to roll it), make a pouch out of the recover wadding, and insert the streamer into the pouch, then insert the pouch into the payload section. push the remaining length of rubber band into the nose cone. Close.

be sure the launch lugs are lined up.
