I have been building and flying CD spool rockets for the last 6 months or so. They are fun, cheap, and easy! (Great combination, huh?)
You can download my CD spool rocket instructions for free. [Note: Instructions require that you have the free Adobe Acrobat Reader installed to view the file.] And you can email me if you have any questions regarding the construction and design of these odd-rocs!

Standard and Mini CD Spools ready for flight
Here is a close up shot of 2 spools. The one on the left was made with 3" mini-CDs and the one on the right was made with standard 4.75" CDs. Both spools are shown upside down and loaded with Estes C6-5 motors.
Spools in flight
Both spools are on the launch pad ready for a drag race. I wanted to do a head-to-head comparison of the spools to see the difference in altitude. The mini-CD spool easily outclimbs the standard CD spool by a good 100 feet. You can see the smaller spool is already higher than the large one.
