B6-2 Engines

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.
