Cluster Engine Rocket Kits Cluster engine kits are those that use two or more rocket engines that are ignited at the same time. The reason to perform a cluster is to have more thrust at lift-off so that you can loft a heavier rocket. But in reality, it is just a lot of fun to see a lot of smoke and fire at lift-off due to the extra motors. For more information on building your own clustered engine model rockets, be sure to get the book: Model Rocket Design and Construction. The kits on this page all use multiple rocket engines. You may need a special clip whip to hook up the motors and insure that they all ignite at the same time when you push the launch button.
