Does anyone on here shoot or shot this head? I bought some and I don't have good flight with them.
Yes but when I mount mine I mount them with the blades at 1 o'clock and 7 o'clock on the arrow. No flight problems.
These were mounted at 12 and 6
Have you spun them to make sure they are on straight? That will make all the difference.
The orientation of a head has nothing to do with flight characteristics. I mount mine at 3 and 9:00 just for consistent sight picture.
If your Deltas are mounted straight and you are seeing weird flight you may have borderline tuning issues that don't appear with target points.
Deltas will fly like darts, same as all other Zwickey heads.
I was going to say the same thing as red. Its a pretty wide head.
Red, Mounting them noon to 6 caused my arrows to dip so I would say they CAN have something to do with flight characteristics. When I moved them to 1 and 7 the dipping stopped.
But what do I know I have only been using them for 50 years.
I too mount mine at 3 and 9 and have no problems at all.
I shoot the 170 grain screw in and they fly the same as my little eskimos.
A big wide BH can be telling.
time to tune!
Been shooting them for more than 40 years. Makes no difference how you mount them as long as you get them on straight. They fly extremely well. A good wind will move them around a little. So will an arrow that's not tuned to the bow or poor form.
I've tried quite a few other broad heads; haven't found any that fly better than a Zwickey Delta.
^^^ what Orion said ^^^
No issues how I mount mine. Mine fly like laser beams. Darts have too much of an arc in them. Ive never seen a dart thrown that was fast or flat.
Been mounting mine @ 3 and 9 just to keep the pole axe out of my sight picture.Bare shaft my arrow tuning and have no problem with arrow flight.Been using them so long that it does not look like my arrow without a Delta on it.

I never paid much attention to how mine are mounted, just get them to spin true. Mine seem to shoot as good as field points. Only problem I have had is I mounted some on short adaptors and they would whistle, that was with 4 blade heads.
Love my Deltas. Been shooting them long enough that I can't remember when I started. If they're mounted straight, they will fly straight.
Might not be mounted straight then, I don't have a spin tester what can I use?
just spin the with the tip on the table like a top
you should be able to tell if they spin true or wobble
not as good as a spin tester but it works
I have used them in the past. Because they are so wide, they really require a well-tuned arrow shaft.
I mounted mine at 3 and 9 o'clock, and I spin tested them (on a table top as mentioned above) to make sure they were absolutely straight.
They are a great head. If you get them tuned correctly they will get the job done as well as, or better than, any other two-blade head out there. They are tough and reliable, and they make a big hole.
What can I do if they are not mounted straight?
glue on or screw in? if glue on wood shaft then just heat the glue and turn them into the shaft a few times like a screw and test them until they spin true.
if screw in then you might need to redo your inserts?
Never had a problem with them with a straight arrow matched in spine to bow. R2
Should I be looking at the head or the arrow I can see wobble in the shaft?
When you spin it, look at the head, and especially at the junction of the head and the shaft. If it shows wobble there, then you need to fix the wobble.
If they are glue-un heads, simply heat them up to soften the glue and tweak them around a bit. then test them again.
How can I fix them for screw in heads with inserts in already?
are you shooting woodies? how many arrows have you tested them on?
I have had a woodie out of a dozen that just wont fly with a blade not sure why maybe just the grain of the wood
someone else would be better at giving you advice for carbons,
Other than making sure they are cut straight and the insert is flush i am not sure.
OK so you have heads with adaptors in them. The adaptors may be glued in with a hot melt glue or epoxy.
If it's hot melt, just warm up the blade until it's moveable and readjust it. I usually keep the point on the shaft and push it into a block of wood, turning the shaft as I do so. This pushes out excess glue and seats the adaptor into the point better.
Spin it like a top. If it spins true, you're done. If not, can angle the shaft on a flat surface and press down near the front of the blade to push it one way or another to align it properly. Do this until you get it straight. May need to reheat a few times to do this. Be careful you don't get the shaft too hot.
If someone has already filed the blade edges, they may have changed the position of the tip, moving it off center. If this has happened, the blade won't spin true regardless of how well it's fitted on the adaptor. About all you can do at that point is attempt to true up the point, or simply eyeball it to get the best fit you can.
If the adaptor has been epoxied in, it will need to be separated from the head and reglued. To do this, will need to take the point/adaptor out of the shaft and heat it until you can separate the two. Be sure to take the assembly out of the shaft. May need to get it very hot, and it would damage the carbon shaft.
Then, try to clean the adaptor and inside of the point ferrule as best you can and glue back together with hot melt glue. And don't use too much glue. Good luck.
As far as what attitude to mount them , if find old pictures of the more famous archers , you will see that there two blade broadheads are mounted 3 and 9 o'clock .
There has been mention that when you release , the paradox is side to side and a vertical blade can grab the air and start steering the arrow off line .
That made sense to me , and I always mount mine horizontal .
I have not had them shoot any different than my field points .
I will add , that you still need to spin test them .
You can take a cardboard box and cut small "V" shapes on opposite sides and lay the arrow in and with the point near some object , rotate the arrow and see where the very poine is on the reference spot .
That's just one of my cheep tricks .
Buy the way , I use a shoe box and it doubles as a container for archery stuff .
I shot them for years. As long as my arrow spine was good the heads flew great.
Very good advice above.
Would the tip being broke do anything?
It could if it made the head off balance or if it was bent .
They must spin true to shoot well. I'll glue them to screw in adapters and give them a spin, trying to get them to spin true before the glue sets. If they wooble after it's hardened I'll spin and find the high side and put the tip on a piece of wood and with the arrow at around a 15 degree angle to parallel put a lot of pressure on it to get it to move. Spin and repeat a couple of times and usually you can get them spinning true without having to put heat to them. If you don't get them spinning true all the tuning in the world won't get them to shoot consistently, but that's true with any broadhead. I mount mine in line with the string but that's just a personal preference.
nh, Of course the tip being broke will affect the ability to get the head on straight. Would not affect flight if the head is aligned properly. After all we've already offered, wouldn't that be obvious. Are you trolling or a newbie?
What Ryan said unless you're using some tiny feathers.

I've had a whistle or so years ago when I for some reason decided I was going to try short adapters...
I bet the whistle you're getting is from short adapters am I correct?
Just wondering why shoot adapters when they make screw in? Is the glue on with steel adapter a more solid set up?
Screw ins DO have adapters....they just come already glued in.
I like to glue my own...I can chose the glue....hot melt or epoxy...depends on what the arrow is intended for....
AND,,,, I can align for true spin.
I use long aluminums....have since the 80s
Ah good point. Thanks

Here you go...
Yes, use to shoot them a lot. Be sure to spin test them. The shaft and nock need to be straight, or it can cause a wobble and when you get the head finally straight, it will still wobble. Roll it over a glass top table, or buy a spinner.
To make a quick arrow spinner I take a piece of 2x4 and four 2" small diameter nails and angle them towards each other forming a "V" two nails on one end and two on the other approximately 18-20in apart. You can bend the nails in or out to level the v's up. Place arrow in the v's and barely touch the broadhead tip to a box or another piece of wood and spin with the flat part of your hand. Watch the tip of the arrow head for run out or miss alignment.
Deltas are great heads, fly great and deadly as the plague. I shot them for a while and never had any complaints about flight or sharpness. My dad still shoots and loves them.
same as a lot of others here, been shooting them for over 35 years, I mount mine 12/6 and they fly and kill perfect . its all in the tuning a wide head will sure show any issues you have..
Now will the extra length of the head which makes the overall length longer if I'm correct will weaken the arrow?
Arrows are typical measured to the back of the head, so the length of an arrow doesn't change based on head design. However the weight of the head will affect the spine. There are lots of good sources for learning more about this. The search function will give you hours of reading on a topic like this.
