I experimented with Blazer vanes this summer and never could get them to fly straight.  I started fletching Norway Predators and really like their flight.  Arrows fletched with blazers fish tail to the left as they come off the rail.  Next summer I plan to spray the rail and riser of the cross bow with vegetable oil and then dust with corn starch to see if the blazer vanes are hitting some thing.  Blazer fletched arrows off my crossbow have poor groupings when compared to 3 and 4 inch Duravanes and Predators. I probably with not be fletching blazers but would like to know why the poor flight.

I'm not a crossbow expert by any means, but it sounds like fletching contact. Blazers are extremely accurate. They are a high profile vane which makes them susceptible to setups with tight tolerances.  |

I've used Blazers in 3 different bows with 4 different arrow and 6 different broadhead combinations...all flew extremely well. |

There is no way to adjust the setup on a crossbow, all of that is machined into the bow. I think the vanes are hitting the riser as they come off the rail. The interesting thing is that the hit position is impossible unless the arrows start to rotate on the rail. I think that they are rotating on the rail but most other XB shooters believe that the structure of the rail prevents arrow rotation. If they are rotating then blazers are out on this bow. Spraying the rail and riser with oil and dusting with a white powder should show any hit spots. Ghost |

Are your vanes fletched straight, offset, helical? I would imagine that you would have to fletch them straight, but as I said before, I don't know much about X bows. |

Most XB shooters like a 4 degree offset and a few do 8 degrees right helix and they say they are have no problems with blazer flight. Straight fletch is not as accurate as a 2 degree right offset. Predators fletched at 2 degrees right offset fly straight and no fishtailing  but at 4 degrees they fishtail. I have tried Blazers at 11 and 8 degrees right helix, 4 and 2 degrees right offset. I have had some Blazers at 2 degrees fly without fishtailing but others fishtail.  The opening in the riser though which the arrow must fly is narrow enough that a rotating blazer will hit the sides. The question is whether the arrows rotate on the rail or after they leave they the bow. High speed photography would be nice. ;D Ghost |

We fletch all crossbow bolts using blazers, straight at my store. No complaints yet.

I have found during the several yrs i have used the Blazer vanes they do rub or hit lightly. I have Excal CB's they rub the aroow slot side as they're shot. Will also contact the limb pocket spacer so i trimmed mine. I usually shot heavy arrows but i have saw them fish-tail now & again. I don' use them any more, went to duravanes

I don' use them any more, went to duravanes I shoot an Excal crossbow. I am glad to see another Excal shooter that has had the same experience. I now use 4 inch duravanes or Predators. I think the 4 inch duravanes are a bit more accurate. Ghost. |

The only way to find out what is happening to Blazer vanes shot out of my excal is to rebuild the arrows. I am resembling my Gold Tip Laser II arrows paying very close attention to squaring the shafts, weighting and bring the inserts to exactly 140 grains, and making sure the inserts are in the true center of the shaft. I have taken 125 grain field points and turned them to exactly 100 grains. This way I know the are perfectly balanced. A cock vane will be fletched on the high side of each arrow shaft. The arrows will be fletched with 4 inch Druavanes. As soon as I get my Xmas present (Spider Web Target) I will set up an in door 20 yard range and test these arrows for true flight. I hope these arrows will set the standard to be used when testing shafts fletched with Blazer vanes.  Since this is cabin fever time an in door target range and new arrows to test will help the time past. ;D Ghost |
