Just listed on eBay my Experimenter Stomp Rocket Package. This is a set designed for teaching and making stomp rocket technology in schools or at home.
High performance Altitude Rockets really earn the name "Altitude".
The stability set has 8-rockets that allow you to experiment with fin location and number of fins, fin shape and even has a tube fin to make.
6-page instruction set included.
Here is a link if you would like to see:

Almost forgot: If you decide to buy; make sure to say you are a PM member for free shipping of the CD! Selling as CD but can email the PDF as well.
