C6-3 Engines

The Estes C6-3 engine is one of the most versatile and reliable model rocket motors available, offering high-thrust performance tailored for a wide range of medium-sized rockets. Designed for flights that balance altitude and recovery timing, this single-stage engine is a favorite among both novice hobbyists and seasoned rocketeers. Whether you're launching for fun or conducting an educational demonstration, the C6-3 provides a consistent and powerful launch every time. With a total impulse of 10.00 Newton-seconds and a 3-second delay, the C6-3 is ideal for rockets that require a shorter coast time before deploying a parachute or recovery system. This makes it well-suited for rockets that are slightly heavier or that benefit from quicker ejection. You'll get impressive altitude while minimizing drift—perfect for smaller launch areas or when recovery location matters. Each C6-3 engine pack includes three engines, along with starters and starter plugs, so you're fully equipped for your next mission. As with all Estes engines, you can count on strict quality control and safety standards. Just insert the engine into a compatible rocket, connect your launch system, and get ready for liftoff. It’s engineered simplicity with explosive fun. The C6-3 is compatible with a wide variety of Estes kits that require a C-class engine and benefit from a shorter delay. It's an excellent choice when you want the power of a full C engine without a long coast phase—especially for rockets with faster descent profiles or lower altitude ceilings.
