B6-4 Engine Bulk Pack

$89.99

The B6-4 is the perfect engine when you are trying to take those simple Estes rocket kits and turn them into a skyscraping powerhouse. Some rockets, like the Alpha III, can reach nearly 600 ft on a B6-4!

The B6-4 stands out for its ability to get rockets up to great heights in a mid-sized schoolyard. The 4-second delay hits the spot for rockets that might need that specific target for their flight profile, making it a great choice for rockets like the Alpha, the Generic E2X, and the Orbis.

The slightly shorter delay means that the parachute will deploy at about the right time for those slightly larger profiles (compared to the others of their class).

Included in this bulk pack:

  • 12 B6-4 Engines
  • 20 Estes Starters
  • 16 Engine Plugs
  • 144 sheets of Recovery Wadding
