Because of the variety of rocket designs and engines used, the height of rocket flights varies. Estes has model rockets that can fly from 100 feet to several thousand feet and all are reusable. Many Estes rockets have secondary features like payloads and multi-stages.
Estes model rockets are designed to be flown over and over. After launching and recovery, simply repack the rocket with wadding, refold and insert the parachute or streamer, remove the used engine casing and insert a new engine, igniter and igniter plug. Now you are ready for another exciting mission!
Even when flying within the wind limits, lightweight rockets can drift significant distances. To reduce the effects of drift beyond what can be done by tilting the launch rod, the recovery system needs to be modified to descend quicker. Various methods are:
A. | Cutting a spill hole: The top of Estes plastic parachutes have a circle that can be cut out. This allows air to flow through it quicker, increasing the descent rate. The drawback is that the modification to the parachute is permanent. |
B. | Reefing the parachute: Gather the parachute's shroud lines together at the mid-point and wrap a piece of tape around it. This prevents the parachute from opening fully, thus increasing the descent rate. For calm days, remove the tape. This modification is temporary. |
C. | Switch to a streamer: Streamers generally descend quicker than parachutes. If the rocket has a parachute, remove it and attach a streamer. Using snap swivels is a great way to make recovery systems easily interchangeable.

We have local schools visit our shop to buy Estes Rockets for lessons and demonstrations, it's a fun way of teaching science and the mechanics involved :)
