B6-4 ESTES EDUCATOR BULK PACK (EST1783)

The B6-4 Estes Engine Bulk Pack is a classroom-ready bundle designed for repeated rocket launches. It provides a reliable supply of B6-4 engines along with the essential ignition and recovery gear needed to run back-to-back flights on Estes rockets or other compatible models.

Inside the kit are 24 engines, 30 model rocket igniters, 24 reusable igniter plugs, and 75 four-and-a-half-inch squares of recovery wadding—enough for roughly 25 launches. Engine selections should follow the impulse-range recommendations for the rockets in use, and this bulk pack offers a convenient, ready-to-go assortment that supports hands-on rocketry education and group demonstrations.
