My Son and I recently saw a Mythbusters in which they tested the feasibility of the Chinese having built a two stage rocket that launched rocket propelled arrows. My son wanted to build one. Their rocket had no recovery, was launched at a 45 degree angle, had a deadly payload, and used canon fuse for a timer. Obviously all of these things would have to change, but I thought we might be able to get the overall feel. I thought I would start with the dragon head.
I drew out the basic outline of the head, then built up the design with Model Magic (a lightweight polymer clay) and covered it with a foam hard coat.
We also started on the "arrows" 18 inch BT 5 tubes with fletchings for fins.
