Few of us even think about the vanes on our arrows when considering performance and accuracy. Yet, it’s the vanes that are primarily responsible for stabilizing and guiding the arrow.

Curved vanes create a higher spin rate, which stabilizes the arrow more quicklyNoticeably tighter groups

1. Noticeably tighter groups
2. Better broadhead flight

Whether your arrows were fletched at the factory or with another fletching tool, the vanes are attached at a simple angle to create spin, but they are not curved. Only the Arizona EZ-FLETCH does true helical fletching, which doubles the spin rate for faster arrow stabilization. The result is measurably tighter groups and better broadhead flight (especially from an out-of-tune bow).

Less turbulence for reduced drag

1. Flatter trajectory

(tested 6 inch less drop at 100 yards)

1. Quieter arrow

Not only do true helical (curved) vanes virtually double the spin rate, they do so while dramatically reducing turbulence, which results in less drag! This, in turn, means flatter trajectory (6 inch less drop at 100 yards) and quieter arrow flight (less chance of a buck jumping your string)!

This understanding led the scientists to the fins on the model rocket, which exist to stabilize the rocket. Model rocket fins, just like the vanes on your arrows, attach at an angle to produce spin, which in turn helps to stabilize the rocket. This technique is commonly called “helical.” As wind catches the angled fins or vanes, it forces the projectile (rocket or arrow) to spin. This spinning, just as with a bullet that’s fired out of a rifle barrel or with a football that’s thrown in a spiral, lends gyroscopic stability to the projectile, which prevents it from tumbling.

All of the competitions’ model rockets had these straight helical fins. What the rocket scientists knew was that a curved fin is stronger and creates more torque in flight. So, they curved or cupped the previously straight fins, making them true helical fins. And their model rocket, because it stabilized more quickly, went higher.

The fact is, the word helix is derived from a greek word that means “twisted” or “curved.” So, in truth, the competitors’ fins were angled and not curved (straight helical) so weren’t actually true helicals.

Hearing this story, Arizona E-Z Fletch applied the same concept to attaching vanes to arrows, something nobody else does, either at the factory or aftermarket. It doesn’t require special vanes, only a specially designed fletching tool. That tool is the Arizona E-Z Fletch Mini or Bolt model.

As rocket scientists, they understood that the faster a model rocket stabilized at takeoff, the higher it could go. In real life, if a rocket is unstable at takeoff, it may never stabilize, given the extreme and constant thrust applied. So, in their world, stabilization is absolutely crucial.
