The Estes E12-8 engine is a powerful choice for educators and STEM facilitators looking to demonstrate advanced principles of rocketry, flight dynamics, and physics. With its high thrust and extended 8-second delay, the E12-8 is ideal for lightweight rockets (up to 12.0 oz) that benefit from long coast phases and high-altitude performance. This engine allows students to explore more complex flight profiles and better understand concepts like momentum, trajectory, and timed ejection events.
The 8-second delay encourages longer coast times before recovery deployment, giving students a clear visual of how timing and engine selection influence flight success. Whether used in upper-stage configurations or single-stage lightweight rockets, the E12-8 provides an opportunity to apply data collection tools, analyze flight paths, and refine recovery systems in a real-world STEM context.
Each package contains two E12-8 engines, two starters (igniters), and four igniter plugs—offering all the essential components for two complete launches. These engines are compatible with standard 24 mm engine mounts and Estes launch systems, making them easy to integrate into existing classroom programs or extracurricular rocketry clubs. Their performance characteristics also make them suitable for secondary and post-secondary education environments where more advanced flight experimentation is encouraged.
Made in the USA and tested to rigorous quality standards, Estes engines are trusted by educators nationwide. The E12-8 helps students deepen their engagement with aerospace concepts, making it an excellent addition to STEM kits, rocketry units, or competitive model rocket programs.
