There the a number of different recovery systems that can be used on model rockets. The system used is governed by weight of the rocket, the size of the rocket motor used, and the wind speed on the day of launch. Parachutes - Parachutes produce the most drag and are typically used on heavier rockets. Streamers - Streamers are long strips of crate paper or plastic and are typically used on lighter rockets.
Streamers typically result in a higher descent velocity due to the reduced drag.
The higher descent velocity results in less wind drift but can also result in more damage to the rocket when it hits the ground. A three tape streamer is depicted in the picture at the right Tumble - Tumble recovery is accomplished by shifting the rocket's CG so the rocket becomes neutrally stable after the ejection charge fires. This is usually done by shifting the position of the rocket motor. Tumble recovery works well on very small rockets but is not commonly used.
