Kits YOU Build!

Composite Engines

Composite Model Rocket Motors. A through G power from Aerotech, Quest and Estes.

For more info on Model Rocket Engines read About Model Rocket Engines.
Composite engines generally have more power per weight of propellant than a black powder engine. They are however, more difficult to light than a black powder engine and most require different launch systems than used for a typical Estes black powder engine (the Quest Q-Jets can use most standard launch systems). Look at the Pratt Go Box, FullBoost or the Aerotech Interlock launch controllers if you need to upgrade your system to fly composite engines (they can also be used with black powder engines).
