broadheads not grouping?

[Becky]

It's not as important as people make it sound.  If they're not aligned but fly good that's fine.

I never knew there was a problem until I read it on here.. I should read less  . They fly exactly where I aim them, I just have to work on the aiming part lol.

I can say with certainty that any straight and true spinning broadhead will fly like a field tip out of a well tuned bow and arrow set up regardless of blade orientation. 

I have to agree.  My guess is that folks who have lined them up and experienced better flight are in the minority.  If broadhead/vane orientation worked for some folks, I'm glad it did, but I suspect there is a different underlying issue that was resolved when you did that, but now you're sold on that being the answer.

Since the arrow is continuously spinning (brought about by offset/helical vanes) I don't see any way that the vanes are hitting the same air current created by the broadhead blades.  It just doesn't make sense to me.  If anything, the vanes are creating the spin and the air current and driving the (straight) broadhead blades to fight against that spin and air current.

I'd like to hear what Rad has to say about this issue.  Where are ya, Rad?

You better get those arrows fixed up fast smossy girl! Before they realize that they are not to fly straight without being lined up. Hopefully nobody tells my arrows either.

can someone come tell my arrows to fly straight? please and thank you.

  they're flying straight (just went and made sure).. I have the same DRT broadheads the OP posted about annnnnd my first hunt is later today and into this weekend! I need to quit reading all this crap because it's makin me freak out and second guess everything  I'll be just fine I'll be just fine I'll be just fine...

Lining up blades with vanes will have no impqct whatsoever on flight... unless the head just happens to spin true with it lined up. Can you cut the vanes off of a field tip arrow and shoot a group at 15-20 yards with 3 field tips and the field tip with vames cut off? Then post a pic. If the bare shaft groups with fletched arrows you should be good. If not some tuning is needed.

I have absolutely improved grouping on broadheads by aligning the blades with the fletches. 

there is no reason at all it would affect flight in any way as long as the broadhead spins straight. How would you line up a 2 or 4 blade head?

I'm only telling you that lining them up has improved my groupings in the past. I've only been shooting broadheads for 30 years. I understand that you may have more experience and that it's made no difference for you. That's my experience. When I've used Zwickey Eskimos, I lined up the blade with the nock fletch. I've never used 4-blade broadheads, so I don't know the answer to that one.

All I was doing was giving the opportunity options to try that worked for me.  I thought we were here to help each other.

Simple as that Bullblaster.
Otherwise what do guys do that shoot 2 or 4 blade broadheads? Fletch with 2 or 4 vanes?
I've shot a couple dozen different broadheads out to 50yds in my yard numerous times. They don't line up with anything cuz I just screw them in tight and shoot them. Once the bow is tuned, they will shoot well or the difference will be so small that a slight sight adjustment will take care of it.
That said, broadhead orientation WILL make a difference out of an out of tune bow. IE: Rest too low. FP hits bull. 3 & 4 blade roadhead hits low. 2 blade broadhead hits low when installed horizontally. When 2 blade installed vertically it hits same as FP. Why? Because immediately off the bow the horizontal 2 blade and multi blade heads catch air because of the rest being too low causing the broadhead arrow to plane down slightly before the vanes can counter act and stabilize the flight. Too late. Already a couple inches low.
I've even got a bunch of old, large broadheads from the 60's and 70's up to over 200grs that fly just fine out of my tuned bow. When out of tune, these huge heads fly horribly because they catch a lot more air than today's small heads.

Areodynamically speaking, if the blades actually created that much air disturbance that it effected the air flow to the vanes, the vanes couldn't do their job of steering and stabilizing the arrow.

From the OP's original post, it sounds like you might need to fine tune your rest. See if this link helps you out.

Sako, thanks for the response, I appreciate the education and information on the how/why.  It explains why both side of this debate think they are right.  Hopefully we all learn from it.

[pianoman9701]

It works for me. That's good enough.

[snarkybull]

It works for me. That's good enough.

It helped me a number of years back. Definitely shrunk my groups.   Whether it makes a difference on my current setup...I don't care.  I am still going to line them up
