The B6-0 / B6-6 Engine Bulk Pack is designed specifically for two-stage model rocket launches. The B6-0 serves as the booster engine, firing without delay for a clean separation, while the B6-6 takes over with a timed delay for upper-stage deployment and recovery. Together, they deliver the dramatic flight profile that makes staging one of the most exciting aspects of model rocketry.
These engines are carefully matched to provide reliable ignition, smooth staging, and consistent performance. That means predictable altitudes, safer recoveries, and confidence for both new and experienced rocketeers. For families, hobbyists, or school programs, the combination ensures a fun, repeatable flight experience every time.
Convenience is built into every bulk pack. With engines, starters, plugs, and recovery wadding included, you’ll spend less time gathering supplies and more time preparing rockets for launch. This is the practical choice for anyone who flies frequently or manages group launch events.
Use the B6-0 / B6-6 engines to power rockets like the Mongoose, Taser Twin, Solar Flare, Cosmic Cascade, Alpha, and many more. Whether you’re chasing altitude or enjoying the spectacle of staged flight, this engine combo delivers safe, consistent, and thrilling results.
