Estes C11-3 Engine Bulk Pack #1726

Estes C11-3 Engine Bulk Pack #1726 is an Estes model rocket engine for model rocketry, launch-day use, and hobby programs.

The C11-3 Engine Bulk Pack gives you twelve ready-to-fly C-class motors engineered for consistent lifts and eye-catching altitudes. Each motor produces a strong but controllable burst of thrust and a 3-second delay that works well with medium-weight rockets — ideal for weekend hobbyists, family launch days, and solo flyers who want exciting flights without stepping up to larger, more complex powerplants. Beyond raw numbers, the C11-3 shines because of its reliability and repeatability. Whether you’re testing trim changes, teaching a new builder the basics, or simply chasing higher flights, these engines reduce the variability that can spoil a flight day. The familiar, crisp ignition and predictable delay let you tune recovery systems with confidence so recovery is clean and repairs are minimal. Technically tuned for mid-to-high altitude performance, the C11-3 offers a total impulse of 10
