The construction is pretty basic. TTM fins, 3 centering rings, eye-bolt in the top centering ring for shock cord attachment.
For recovery, I used a loop of 1/4 inch bungee cord through the eye-bold on the motor mount. This was threaded through a Nerf Ball to serve as zipper protection. Fifteen feet of 9/16" tubular nylon was attached to this with a quick link.
RocSim showed that 8 oz. of weight would be needed for the flight if I used the PRO 38 J285. By installing a mollybolt in the base of the nose cone, I was able to add the weight in a way that let me change it if needed. I replaced the bold with a long eye-bolt so I could attach the shock cord to it. Mark Gholston gave me the idea and it worked great.
Because it is so easy to lose a rocket in the scrub at the Brothers launch site, I added a Radio Shack Personal Alarm to the shock cord with the pull loop attached to the nose cone eye-bolt.
Finally, for motor retention, I used a snap ring retainer from Binder Designs. It is attached using JB Weld.
