The Estes B6-2 engine brings dependable, real world performance to your backyard launches. Designed around a stable thrust curve and a short, accurate delay, this engine helps rockets lift cleanly and deploy recovery at the right moment. Its compact 18 mm diameter and modest weight make it a versatile option across many beginner and intermediate kits, so you get great flights without fuss.

Beyond raw numbers, the B6-2 stands out for reliability. Estes manufactures and tests every engine to strict quality standards so each pack delivers consistent ignition and burn characteristics. That consistency means less guesswork for recovery planning, more successful flights, and more confidence each time you head to the pad.

Use the B6-2 when you want a satisfying altitude with predictable recovery. It is well suited to rockets that weigh up to about 4.5 ounces with the engine installed, and it performs especially well in lightweight kits where a clean, steady boost yields smooth flights and reliable ejection. Whether you are teaching someone to fly, running a family launch, or refining your build techniques, the B6-2 is a dependable engine to have on hand.

Each pack includes multiple engines plus starter accessories so you can get flying right away. Stock up for practice sessions, club launches, or classroom projects and enjoy consistent flights that make every launch day more fun. Ready to fly? Add the B6-2 to your next order and get back to the part everyone loves most - watching it climb.

The Estes B6-2 is a dependable single stage model rocket engine built for consistent, exciting flights. Engineered to deliver a steady boost and a predictable delay, the B6-2 is ideal for hobbyists and weekend flyers who want repeatable performance and easy planning for recovery. It works especially well in standard 18 mm engine rockets and is a great match for a wide range of Estes kits and custom builds.

What makes the B6-2 a go-to choice is its balance of power and control. With a crisp, smooth thrust profile and a reliable two second delay, these engines give predictable apogee timing so you can plan recovery with confidence.
