Exactly my thoughts on this paul, it just seems impossible to get an arrow, even with sraight fletch, to now spin. This would require absolutly no wind, rock hard vanes, and a perfect release from the bow without any twitch. Seems highly unlikely.

I was actually thinking about this last night. I know they spin, but how much do they spin is what i was wondering? I guess i would probably have to have a slow motion camera to figure that out.

Your information is wrong. All arrows spin....some may only spin a little bit, but they do. I shoot very close to a straight fletch and the orientation of my fletchings in the target are not the same as when they left my bow. I can't believe an arrow could be made symmetrical enough to not spinat all. Heck, I think even bare shafts spin when shot....not a lot, but some.

Go look at the link I gave you. It's not MY information.

You can take it up with them.

Yes they do, mine are fletched with a strong right helical.

A little something for the math wizards:

As Mobow mentioned your arrows don't make hundreds of revolutions on their way to the target generally like 2-5 actually. BUT, that being said they still spin at an extremely high rate... The proof's in the numbers.

For easy figuring we'll say the target is 20 yards away (60ft) and your arrow is traveling 300fps.

Arrow velocity: 300fps x 60s/min = 18,000fpmin
Distance: 60ft
Time of travel: 60ft / 18,000fpmin = .003min
Rotations: 3.5
Speed of Rotation: 3.5 rotations / .003 = 1166.7 rpm

So your arrow actually spins around 1100 rpm's.

Not saying your wrong, and you probably know more about this than i do, but I just shot my Blazers with only a slight helical 10 times. I put a blue dot on the cock vane down blazer and 10 out of 10 times the blue dot fletching was facing down just as it was knocked on the arrow. Note that this was at about 8 yrds in my apartment so i dont know if distance has anything to do with it or not.

Dubbya- Thanks for the Math lesson. I guess figuring it was easier than i thought.

yea. Mine are offset. I don't know to what degree.

Jeff,

I was given some Carbon Express Eliminator Hunter Arrows for Christmas one year from my BIL and they came straight fletched. (I posted about it) I had them re-fletched with a 4deg off set. I still use them out of my Fred Bear Code, they seem to be a pretty good arrow....

I've since purchasedsome Easton Axis ST's for my Mathews but I got the bare shafts and had them fletched the way I wanted them to start with (4deg offset)

A straight fletch will still shoot very good and with a field point attachedit's difficult to tell the difference in flight between the two. Put on a broad head or shoot outside with any type of wind and you will notice the difference. A straight fletch just isn't as forgiving as an offset or helical as there is no imparted spin to help stabilize the arrow in flight. Other factors such as FOC and spine become even more important for good arrow flight with a straight fletch.

There are some who still shoot a straight fletch.....Not me though......I need all the help I can get!

My arrows are in the "No Spin Zone"

Yes they spin

Is this like a trick question or do people really question wheather thier arrows spin?
