The Estes C11-5 engine is a powerful single-stage engine built for mid-sized model rockets that need a strong boost off the pad. With a 24 mm diameter and 10.00 N-sec of total impulse, it delivers robust performance for flights requiring a medium delay between thrust and ejection.

With a 5-second delay and high thrust output, the C11-5 is a solid choice for rockets weighing up to 5 ounces. It provides consistent, dependable launches and is ideal for rockets that need a little more power than a B engine can offer.
