E12-0 Engines

The Estes E12-0 is a 24 mm booster-stage engine created specifically for use in two-stage rockets. With no delay charge, a thrust duration of 2.6 seconds, and a total impulse of 28.80 N·s, it provides the initial power needed for reliable stage separation and successful second-stage ignition. This makes it a valuable teaching tool for illustrating real-world aerospace concepts in a classroom or camp setting.

For educators, the E12-0 offers both safety and dependability. Its design ensures predictable performance, so students can concentrate on observing rocket staging and analyzing flight results rather than troubleshooting inconsistent motors. The immediate boost and clean handoff to the second stage highlight critical concepts such as thrust, acceleration, and momentum transfer.

Each pack contains 2 E12-0 engines, 2 igniters, and 4 igniter plugs — enough for multiple demonstrations or small group activities. The engines are best suited for rockets weighing under 16 ounces (including engines), making them compatible with a wide range of Estes classroom kits and custom designs. By keeping lessons hands-on, the E12-0 helps transform theory into memorable, practical learning experiences.

Whether you’re leading a science class, running a youth program, or organizing a camp activity, the Estes E12-0 booster engine is a simple, effective way to introduce students to multi-stage rocketry. Backed by Estes’ reputation for safety and quality, it gives educators confidence while sparking curiosity and excitement in every launch.
