Does anyone on here shoot or shot this head? I bought some and I don't have good flight with them.

Jon Stewart · « **Reply #1 on:** July 04, 2016, 05:57:00 AM »

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.

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.

nhbuck1 · « **Reply #15 on:** July 04, 2016, 11:14:00 AM »

Might not be mounted straight then, I don't have a spin tester what can I use?

Longtoke · « **Reply #16 on:** July 04, 2016, 11:34:00 AM »

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

smokin joe · « **Reply #17 on:** July 04, 2016, 11:40:00 AM »

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.

nhbuck1 · « **Reply #18 on:** July 04, 2016, 11:42:00 AM »

What can I do if they are not mounted straight?

Longtoke · « **Reply #19 on:** July 04, 2016, 11:44:00 AM »

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?
