C11-3 Engines

Power your mid-sized model rockets with confidence using the Estes C11-3 Engines. These powerful motors are designed for launches that require more thrust than a standard B engine but don’t need the altitude of a D-class engine. With a total impulse of 10.00 N·s, the C11-3 provides reliable, solid acceleration and a controlled 3-second delay before ejection—ideal for rockets with larger airframes or heavier payloads.

The 3-second delay gives rockets just enough time to reach peak altitude before deploying the recovery system, ensuring safe and consistent descents. Perfect for mid-weight kits or scale models, the C11-3 bridges the gap between lower and higher power flights, making it a versatile choice for rocketeers looking to optimize performance without overshooting field constraints.

Each pack includes 2 C11-3 engines, along with 2 starters and 4 starter plugs, so you’re ready for multiple successful launches right out of the box. Count on the Estes C11-3 for dependable mid-power performance that takes your model rocketry experience to new heights.
