Overview

The Estes C6‑5 engine is a classroom-friendly, single-stage standard engine that supports a wide range of STEM learning activities. Designed for model rockets under 4 oz (113 g), this 18 mm engine offers the perfect balance of thrust, delay, and reliability—making it ideal for student launches in schoolyards, open fields, and camp settings. Each pack includes three engines, four igniters, and four starter plugs, providing everything needed for multiple student groups to participate in hands-on rocketry.

With a total impulse of 10 N‑s and a burn time of 1.6 seconds, the C6‑5 produces a powerful yet manageable launch profile suitable for intermediate-level classroom experiments. The 5-second delay between motor burnout and ejection allows students to observe coast time and apogee performance—key concepts in aerospace and physics education. It’s an excellent tool for reinforcing principles like Newton’s Laws of Motion, acceleration, and energy transfer.

The C6‑5 fits any Estes rocket that uses standard 18 mm engines and is commonly paired with educational models like Alpha III®, Generic E2X®, and AstroCam®. This engine supports stable, consistent flights, making it easy for educators to run repeatable tests and demonstrations across multiple student launches. Its reliable ejection charge ensures safe parachute deployment, so students experience a full launch-recovery cycle.

Backed by Estes’ long-standing commitment to quality education products, the C6‑5 engine is trusted by teachers, mentors, and STEM coordinators across the country. Whether you're introducing rocketry for the first time or guiding students through a multi-flight project, this engine delivers the performance and consistency educators need for a successful aerospace learning experience.
