Estes B6-0/B6-6 Engine Bulk Pack #1784

Estes B6-0/B6-6 Engine Bulk Pack #1784 is an Estes model rocket engine for model rocketry, launch-day use, and hobby programs.

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
