Overview

The Estes A8-3 Engine Flight Pack is a classroom-ready solution for safe, engaging model rocket launches. Designed for lightweight rockets and first-time flyers, the A8-3 engine provides low, controlled thrust and a 3-second delay—making it ideal for educational environments where consistency and safety are key. Students can clearly observe each phase of flight, from launch to recovery, enhancing learning and hands-on application of STEM concepts.

This all-in-one pack includes three A8-3 engines, four starters, four starter plugs, and 12 sheets of recovery wadding. That means instructors have everything needed for multiple launches with built-in backup components. The recovery wadding protects parachutes from heat during ejection, helping extend the life of each rocket and reducing the need for frequent replacements.

With a 0.8-second thrust duration, the A8-3 offers a stable and gradual ascent suitable for small field launches and close-range observation. The 3-second delay provides ample time for students to track the rocket’s flight path before recovery deployment, helping reinforce lessons in trajectory, force, motion, and aerodynamics.

Whether you’re leading a classroom activity, club program, or summer camp, the A8-3 Flight Pack supports safe, repeatable experiments that make rocketry approachable and fun. Pair it with compatible Estes rockets like the Alpha or Wizard to create an unforgettable learning experience with real-world physics in action.
