Step up your flight power with Estes B model rocket engines. Offering more thrust than A-class motors, B engines are a great choice for beginner and intermediate rocketeers ready for higher altitudes and longer flights. These 18mm engines are perfect for a wide range of compatible Estes rocket kits.
Choose from various delay times to fine-tune your launch. Estes B engines—like the B6-4 and B6-6—give you options for matching your rocket's weight, altitude expectations, and recovery system. Whether you're flying in a backyard or on a school field, B-class motors provide smooth, stable performance.
Built for reliability, ease of use, and consistent ignition. Each engine pack includes igniters and recovery wadding plugs, making launch day prep fast and frustration-free. Estes B engines are ideal for individual hobbyists, classrooms, and STEM programs looking to explore next-level rocketry.
Compatible with dozens of Estes model rockets. If your rocket supports standard 18mm engine mounts, upgrading to a B-class motor can dramatically boost your altitude and fun. Explore the full collection of Estes B engines and find the perfect fit for your next mission.
