THIS ITEM IS A DANGEROUS GOOD AND CANNOT BE POSTED
Estes model rocket engine bulk packs are available in four total impulse ranges: ½A (mini engine), A, B or C (standard engines). These packs may be used for the rocket bulk packs or other Estes rockets. Whether you are launching rockets at school with students, at a youth group activity or rocket club monthly launch, Estes engine bulk packs are a must.
The C6-5 is a standard engine designed for rockets weighing less than 4 oz. and offers more power than both the A3-8 and the B6-4. The C6-5 can fit the Alpha III, the Hi-Flier, the Viking, the Generic E2X and the Wizard. This 24-pack includes 24 model rocket engines, 30 starters, 24 starter plugs and 75 squares of recovery wadding.
