BATON ROUGE, Louisiana USA — Giant Leap Rocketry, Inc., introduces an anti-zipper device called The FIREBALL. It is intended to prevent zippers by cushioning airframes from the severe shock of ejection.

Zippers are linear airframe fractures caused by the impact of shockcords on the lip of a rocket airframe during deployment. They are a very common form of damage, causing many flyers to loose their certification attempts.

The FIREBALL softens and spreads the destructive force of shockcords on the lip of the airframe. It is made of 100% KEVLAR™ for strength and heat resistance. Ed at Giant Leap maintains that the FIREBALL is easy to install and "is the next best thing to rocket insurance."

Giant Leap claims the FIREBALL has the following features:

• It is built with Tubular KEVLAR shockcord (LARGE: 1/2" 5500 lbs. test / SMALL: 1/4" 3000 lbs Test).
• It has a NOMEX™-sewn loops in KEVLAR that attach to your existing recovery system. Tests reveal that the loop is stronger than the cord itself.
• The FIREBALL has stainless steel clamps that won't rust or tarnish.
• The internal foam is noncombustible and high density. It is neither a Nurf-ball that bottoms out & cracks airframes, Nor a hard tennis or rubber ball which can crack an airframe.
• The FIREBALL saves weight because it alleviates the need for beefy & heavy anti-zipper rocket construction.
• The "tail" or free end of the FIREBALL is 5 feet long to fit most applications.

FIREBALL SMALL (for 2.6” and 3.0” airframes) Wt. 2 oz. 3000 LBS TEST $11.99
FIREBALL LARGE (for 3.9” and larger airframes) Wt. 4 oz. 5500 LBS TEST $14.99
