A3-4T Engine Flight Pack

The Estes A3-4T Engine Flight Pack is an ideal choice for educators bringing hands-on STEM learning to life through model rocketry. Designed for lightweight rockets using 13mm mini engines, the A3-4T offers 2.50 N-sec of total impulse with a thrust duration of just 0.6 seconds—resulting in quick, responsive launches that keep students engaged. A 4-second delay supports a predictable coast and recovery phase, making it easier to plan launches and analyze flight data.

Compact, reliable, and classroom-friendly, the A3-4T engine is well-suited for rockets under 2.0 oz (57 g), offering consistent performance across repeated launches. With a max thrust of 6.8 newtons, it delivers enough power for educational flight activities without overwhelming beginner-level rockets. These attributes make the A3-4T a trusted option for curriculum-based programs that value precision and safety.

The A3-4T Engine Flight Pack includes four engines, four starters, four plugs, and twelve sheets of recovery wadding—everything you need to support multiple student launches without complicated prep. This all-in-one pack saves educators valuable time and helps ensure a smooth classroom or field launch experience.

Estes Education supports inquiry-driven learning through rocketry, and the A3-4T Engine Flight Pack is a smart, scalable tool for engaging students in physics, engineering, and aerospace principles through real-world experimentation and observation.
