C11-0 Engines

Power your two stage flights with the Estes C11-0 booster engine. Built for dependable, high thrust performance in lightweight rockets, this booster is ideal for hobbyists who want clean, repeatable staging and confident launches for rockets under 6 ounces including the engines.

Designed for rocketeers who value consistency and ease of use, the C11-0 delivers a strong, short burst of thrust that helps heavier second stages get clear of the launch rail fast and true. Its steady, well controlled burn and precise manufacturing mean predictable flights you can plan around, whether you are flying alone in the backyard or at a club launch.

Each pack is sized for convenience and immediate use. With robust peak thrust and a compact 24 mm form factor, the C11-0 pairs perfectly with standard 24 mm Estes engines to form reliable two stage combinations that reach higher altitudes without extra fuss.
