fletching question

[Rick_R22]

whats the difference between straight right and left helicals

[Low Fence]

Straight fletching have NO degree of curve to the vane from front to back and will not cause an arrow to spin, which is critical to forgiveness and accuracy.

Helicals have an amount of "angle" from front to back (many different degrees) causing an arrow to spin upon release. This will cause the arrow to correct itself faster becoming more forgiving, stabile, and accurate

And the right and left, well that just tells you the way it spins, as view from the shooter! A left helical will spin counter-clockwise!

o ok thanks 3children and low Fence

straight fletching WILL cause the arrow to spin. just at a different RPM that a helical fletch. Also you have a LOT less clearance issues with fixed position rests, and creates less drag through the WB rest. It kinda cracks me up when people say straight fletch doesnt spin. Bare shafts even spin with no fletch on them!!!!

[atexx2]

The advantage of helical fletch is it spins your arrow like a football sprial spins and provides greater accuracy. The dissadvantage is arrow rest contact.

But if you have a drop away style rest that is elliminated.

Straight fletch advantage is that it fits between your arrow rest prongs without contact, disadvantage, no spin = less accutrate.

I hate to say this but you are very wrong about a straight fletch being less accurate.

[Rick_R22]

so what is it does straight spin and accurate or helix spins and his accurate

Please educate me on how straight fletching spins the arrow.
Does it spin clockwise or counter clockwise?
Does it spin the same way consistently?
How does it override the steering effects of a BH blades?

Cmon Rocky, straight fletch will turn the arrow consistently. If you put a straight line down the center of a bare shaft and shoot it, the shaft spins. Straight fletch will cause the arrow to spin. It spins clockwise consistently. Why does everyone refuse to believe that a straight fletch spins the arrow?? If it didn't work, then why in the WORLD would any jig makers offer a straight jig?? I do agree that to ensure overriding the steering effects of a BH, the a helical is better than straight, but it still works. Basic aerodynamics says that because the air is moving faster across the point of the arrow than down the shaft, a natural rotation is created. THAT is why even bare shafts spin. I challenge ANYONE to disprove that!!!

I prefer to shoot straight for clearance issues with my fixed rest. You can shoot what you want, and factory built arrows generally have a right helical. Neither is better, they are just different, and they both work quite well.

this pretty well explains it!

I suppose you made your point,(although the rocket analogy eludes me) but why does it always spin clockwise, and if helical is better at overriding the steering effect of blades, why would you use straight fletch, and why would you use a rest that required you to use straight fletch when there are so many that don't?

[bowhuntntxn]

personally i prefer a fixed rest over a drop away rest or containment type. and it is nothing more than personal preference, not because one is better than the other. Same as using straight fletch as opposed to a helical fletch. It would take a long time to explain why it spins clockwise, and something about the earths rotation and gravity and honestly it has been a long time since the aeronautics classes. So I will go with my Joe Dirt reference: "How does a rainbow work?" ... "It just does!"

[rocky]

At what point is fletching necessary?
Bare shaft-spins
Straight fletch -spins
Offset fletch - spins more
Helical fletch -spins even more.
Arrows don't have "gimballing" .
At what point in a hunting arrow is less spin better?

[bowhuntntxn]

here is a thought. instead of chasing me around with silly questions how about answering the OP question about the difference in fletching. I pointed out that a straight fletch will in fact cause the arrow to spin as opposed to others who say it wont. Now you are dogging me with questions about gimballing.. seriously?!?!? If you prefer hard right fletch tell the man why you prefer that. If you prefer one of each tell him that is what you like and why you like it. I dont think the questions you are asking me are adding any useful information to the OP.
