C6-3 Engines

The Estes C6-3 engine is a dependable and high-thrust motor ideal for classroom and STEM learning environments. With its short 3-second delay and consistent performance, it’s perfectly suited for rockets that benefit from quicker recovery system deployment—making it a smart choice for lessons that focus on flight dynamics, trajectory, and safe landings. Designed with educators and students in mind, the C6-3 helps bring real-world physics to life.

Featuring a total impulse of 10.00 Newton-seconds, this engine delivers impressive lift for medium-weight rockets while keeping recovery within a manageable range—ideal for use in schoolyards, open fields, or organized launch days. The 3-second delay offers a shorter coast phase before parachute deployment, supporting more controlled recoveries and quicker turnaround between launches.

Each C6-3 three-pack includes everything needed for ignition: three engines, starters, and starter plugs. Estes engines are built to meet strict quality and safety standards, ensuring a reliable flight experience for student-led experiments or group activities. It’s an accessible and exciting way to introduce rocketry fundamentals and Newton’s laws of motion in action.

The C6-3 is compatible with several Estes rocket kits designed for educational use that call for a C engine with a shorter delay. Whether you’re teaching aerospace concepts or building confidence in hands-on STEM applications, this engine delivers the reliability and power to elevate your classroom experience.
