RE: New NAP Vanes(Pic)!
I do admit I have this mental image of the arrow sounding like an ah-ooga horn as it's zipping downrange.
Also - have you ever seen a slow mo of a regular plastic fletch being shot[
]I can imagine the contortions this one will go thru

RE: New NAP Vanes(Pic)!
They had them on a mechanical display at a speed supposed to simulate arrow flight (it was kind of like a wind tunnel effect). They were no noisier than the full helical fletched feathers spinning next to it, and it was spinning MUCH faster than the feather equipped arrow.
They are soft like an AAE or Duravane, so durability will probably be about the same. [:'(]
I'll try 'em. But I think the price point will be highly detrimental to their sales numbers. Guys aren't going to spend 40 bucks for a 100 pack.
And GV, you are pretty much on target according to what the NAP engineer was telling me.

RE: New NAP Vanes(Pic)!
Hi Guys,
The vanes actually weigh 11.5 grains each so the total weight as compared to a standard plastifletch is about 10 grains heavier.
The spinning machine at the show had air flow equal to about 40 MPH or 58 FPS. So it was about 1/5 normal arrow speeds of 260 FPS. The RPM readout we used for the display would increase at higher rates of air flow.
The Micro-Grooves we use on one side do two things. First they create a difference in air pressure side to side which creates spin. Second they provide rigidity which prevents the vane from flopping wildly in the air stream. The rigidity helps to stabilize (prevent flapping) the vanes almost immediately out of the bow. This effect allows the kicker at the back end to function more effectively as spin increases.
The kicker is molded secondarily after the base. The profile is such that the vane can be used in any standard fletching jig or automatic fletching machine.
The durability is similar to other such plastic products.
In a speed decay test the 20 yard speed of the QuikSpin vane was 246 FPS, while a plastifletch was 247 FPS and 4 inch helical feather was also 247 FPS.
Down range precision is increased as a function of being able to stabilize the arrow almost immediately out of the bow and maintaining aerodynamic stability due to spin. Basically it is the same idea a gun manufacture uses when making a highly rifled barrel for target shooting. (I guess one could say it is kind of like rifling for your bow).
The ability to stabilize a standard broadhead is also increased.
Noise is about the same to the human ear as a standard plastifletch.
We do not have all this information on our website yet, so I thought I'd add a bit to the discussion.
If you have any more questions please feel free to call New Archery Products at 800-323-1279.
on a personal note...I think you will all be pleasantly surprised at what these things will do!

RE: New NAP Vanes(Pic)!
Cary,
Thanks for the info! Sounds very intriguing. The Axis ST and these sound like the perfect combo. Of course, if the price is what is previously mentioned, not many people will be shooting the same spot for groups!!![][][]

Yeah, I got that feeling too...When I read what he wrote on how the vane functions I had a constant grin...I couldn't believe I was so near the ball park with my explanation just from looking at it.
