Oh crap! Yet another variable.[:'(]

Arthur,

I think I am following what you are saying but it would seem like there was a point of deminishing returns considering the fact that broadheads typically get more eradic at higher speeds. Since the resistance on the broadhead and the fletching would theoretically increase proportionally I can't help but think there is a belle curve in the effectiveness of increased drag? Would you agree?

I agree silent,there will be a point that there will be so much turbulence that stabilization would be next to impossible.


Elk,you are on the money with foc,I agree but if the heavy,slow arrow has the same foc as a lighter one it will still need more Fletching.Slow arrow will become unstable in flight unless their is sufficient stabilization on the back.The speed will actually help stabilize a light arrow to a point.


I do not agree with you that speed needs to be increased to increase ke,you increase momentum AND ke when shooting a heavier arrow out of a bow.The speed decreases but ke increases.


Arthur,you are catching on to what my question is.Yes there are many other variables beyond foc,momentum and ke.Drag coefficients is one.Diameter is another.How about spine,that is another huge variable.Imo their is no 1 thing that does everything,they all are needed and should be taken into account when setting up equipment.


All of these variables is why I have always said to get a well balanced arrow and stay within the parameters that Easton gives you on their hunting charts for arrows.


Aluminum needs some thicker walls to be effective,imo so naturally they will be on the heavy side and carbon doesn't need to be as heavy,IMO to do the same job .As to how much,that is debatable,heaven knows we have debated it.
But maintaining a good foc and a proper spine will always be at the top of my list.

I certainly believe there is a point of diminishing returns, but a bell curve? I doubt it's so. If it were a nice bell curve, someone could sit down and come up with a foolproof mathematical formula to plug numbers into and always come up with the perfect arrow setup for whatever speed you were looking to get. So, if it really was that easy, I'm sure some brainiac would've already figured it out and we'd all be using calculators to make arrow/fletching/broadhead/FOC selections.

You know, TFOX, there are so many things going on with arrows that it really boggles the mind. And I am one that is easily boggled. That's probably why I like my slow old logs so much. They're easy to tune, outside forces don't affect them as much as they do light, fast arrows. And even with my imperfect form and tuning skills, I can still get great arrow flight and accuracy.

Arthur,I am not just talking about the time it takes but how much easier that it might stabilize.Meaning that an arrow with more ke could starighten back out EASIER than one with less,making it more forgiving to torque.



Please don't take any of this too serious,I am just being a bit out there right now.

Yea Arthur,when throwing logs it is simple,IF you get enough fletching and foc.

In case anyone was wondering, yes, I did say "I am not a good enough archer to shoot a super speedy setup." And I am perfectly comfortable with that.

TFOX, simple has it's virtues.

Simpleton [8D] Some how I don't think that is the case.

TFOX. there is a website that calculates everything for you. You put in the fletching info. Arrow weight and length, tip weight etc. and it spits out the drag co-efficients etc. It is kinda interesting even if a person never uses it. Your are absolutly correct. Every thing that you mention has its part in arrow flight. Whether it is neccessary to the average archer, probably not. But it gives us something to think about when we are not hunting!!!!
