Overview

For model rocketeers looking to push performance to the edge of the atmosphere, the Estes E12-8 engines deliver powerful thrust and long-delay timing for high-altitude, precision flights. These engines are engineered for rockets weighing up to 12.0 oz, making them ideal for lightweight, streamlined designs that aim for maximum elevation. With a strong initial boost and an 8-second delay before ejection, the E12-8 is purpose-built for upper-stage use or flights that require extended coast times.

The 8-second delay allows your rocket to reach its peak trajectory before deploying its recovery system, ensuring smooth and efficient descent. This extended coast phase is especially effective for rockets designed to take advantage of high-speed, high-altitude performance. Compatible with standard 24 mm engine mounts, the E12-8 opens up a wide range of flight possibilities for advanced single-stage flights or multistage missions where precise timing is critical.

Each pack includes two E12-8 engines, two starters, and four igniter plugs—everything you need to prepare for two successful launches. Whether you’re expanding your Pro Series II missions or fine-tuning the performance of a lighter rocket, the E12-8 adds reliability, power, and altitude potential to your launch lineup.

Proudly made in the USA, Estes engines are rigorously tested for quality and safety. The E12-8 continues that tradition, giving rocketeers dependable performance and extended delay timing for specialized launches. Always follow engine guidelines and safety protocols to ensure a successful flight and recovery.
