The Estes C6-7 model rocket engine is a powerful, high-thrust motor designed for upper-stage flights and lightweight, single-stage rockets. As a standard 18mm engine, the C6-7 provides a strong 1.6-second burn time, delivering consistent acceleration to propel rockets to impressive altitudes. With a 7-second delay before parachute deployment, this engine is ideal for rockets that require an extended coasting phase to reach peak altitude before safely descending.

With a total impulse of 10.00 Newton-seconds and a maximum thrust of 15.30 Newtons (3.4 lbs), the C6-7 is perfect for rockets weighing up to 2.5 ounces (71 g). The extended delay time ensures that the rocket reaches its full trajectory before the recovery system is deployed, providing a smooth and controlled descent. This engine is best suited for lightweight model rockets designed to take advantage of its extended coast time and high-performance lift capacity.

Each C6-7 engine pack includes three engines, four starters, and four starter plugs, ensuring you have everything needed for multiple launches. Estes engines are engineered for reliability and precision, giving rocketeers the confidence to launch with consistent ignition and predictable flight performance. The parachute ejection charge activates at the perfect moment to ensure a safe and stable landing, allowing for easy rocket retrieval and quick reusability.
