    Hello every one , I have been following the forums for a while and have enjoyed it . Very informative.
    I have a question about broadhead alignment with a four blade vs a three blade. I know with the three blade you align the blades with vanes , so how would you do it with the four blade or does it matter?

    Welcome aboard Lee…

    I’ve never taken the time to line my broadhead blades up with my fletchings. The arrow is spinning so lining them up doesn’t mean the blades and the fletchings are going to cut through the same path anyway (unless your arrow speed is perfect, you can do the math). Field tips shoot better than fixed blade broadheads, if tuned right the difference in accuracy is small enough I’m still confident with a broadhead. Things like broadhead alignment concentric with the shaft & nock fit to the string and the right arrow are more important than aligning blades with fletching. If you want to line them up, go for it. It won’t hurt but I don’t think it will help either. Like I said I never took the time and my NAP thunderheads sit in the same three inch circle from 20 to 60 yards that my field tips sit in.

    When I did use a 4 Blade head… (I use 3 blade Thunderheads now)…. I had the 4 blades set like “X” instead of like “+”. Better clearancs at the riser. Now draw a “T” (representing fletching) through the “X”.

    For the first 8′ to 10′ off the launcher the arrow is not spinning, and the surface area of the blades has a noticeable affect on overall accuracy.

    With a three-blade fixed-blade, the orientation is not critical, since no matter what the orientation, the overall exposed blade surface area is about the same. I do like to orient my 3-blade broadheads so that the sight picture looks the same, usually either one blade up or one blade down … doesn’t affect accuracy, but does affect my confidence level.

    With 4-blade fixed-blade there is a difference, similar to 2-blade fixed blade. For a compound bow shot with release aide, the arrow flexes in the vertical plane, up/down.

    You want a consistent aerodynamic force on the blades in the first few feet off the launcher until the vanes can take control. You can’ chose a maximum aerodynamic force or a minimum aerodynamic force. I recommend choosing the minimum aerodynamic force, which is to have the 4-blades oriented in an “X” rather than a “+” .

    … hope this makes sense and helps. [=}=]
