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.

Actual Customer Comment:
"Apogee is 'best in class' for 'model' rocketry.  The best website, most useful 'intro' 'how to' and 'technical' information.  RockSim is in a class of its own, it has no real competitors.  Unquestionably, Apogee has the best customer service in the 'model' rocket business.  I wish you were in the High Power Rocketry business..." -- Bret Simpkins
