Air Rocket with Fin Collar

This rocket fits on the launch tube of the air-powered system made by AirRocketWorks.com. The fin collar is separate so that you can launch with and without fins to see the difference in flight. You can then fashion your own fins out of cardboard and fit them into the collar to see how shape and size impact flight. The collar has a groove to fit onto a ridge on the rocket that keeps the collar from spinning. Also, I found that the collars break every 10-15 launches, so I print extras.
