B6-2 Engines

The Estes B6-2 engine is a standard single-stage model rocket engine designed for reliable flight performance in classroom settings and group launch activities. With a total impulse of 5.00 N-sec and a peak thrust of 12.10 newtons (2.7 lbs), this 18 mm diameter engine delivers a strong, consistent boost for rockets weighing up to 4.5 ounces (127 g). Its 2-second delay allows for a brief coasting phase before activating the ejection charge—helping students observe stable flight paths and effective recovery system deployment.

Engineered for rockets requiring a quick boost and early deployment, the B6-2 features a thrust duration of 0.80 seconds. This makes it particularly well-suited for classroom demonstrations, STEM programs, and group launches where flight predictability and safe recovery are essential. Its performance characteristics offer educators a valuable tool for reinforcing physics and engineering concepts in a hands-on learning environment.

Each pack includes three B6-2 engines, four starters, and four starter plugs—providing everything needed for multiple launches in a classroom or group setting. The inclusion of starters and plugs simplifies the setup process and ensures reliable ignition for every flight. Convenient packaging supports efficient lesson planning and minimizes preparation time for educators.

With Estes' proven track record of quality and flight reliability, the B6-2 engine is a trusted choice for educational rocketry programs. Its consistent thrust, short delay, and dependable recovery timing make it an ideal option for student projects, flight demonstrations, and STEM-focused activities.
