      This lets us use the smallest feather possible with the same affect as a bigger one. Correct ??

      Ok, here’s the big question. Is the FOC gain really that great to warrant this ??? Is there really that much difference from 3×5 inch to,say, 4×3 inch ??

      Yes it is! But you also need EFOC or better UEFOC arrows.

        Sorry, but I wasn’t at home for the weekend.

        If I remember right O.L. wrote about it on TG, but it was pulled.

        He said it would be like on an airplane wing. The wing is on the backside created as a tearoff edge (turbulator) so air flow becomes turbulent, goes under the wing and lifts the plane.

        For an arrow: The feathers job is to stabilize the arrow. They are doing this by draggging (acting as a brake). The more air drag the fletching has the more it will stabilise the arrow.

        So you can glue on bigger feathers or you increase the air drag.

        I played it with wood arrows. The turbulator made the arrow acting stiffer, just like lowering the brace height. It’s not 5# but it’s noticeable.

        I’m also not a physician, so I hope I explained it right.

          Turbulators are changing the laminar airflow to a turbulent airflow, which produces more pressure on the feathers, so smaller feathers stabilize like bigger one’s.

            With the TuffHead being almost indestructible future sales are dependent on lost broadheads. You are not cooperating….LOL:D

              in reply to: Arrow length as substitute for more FOC #45848

              Years ago I tested it with wood arrows (Northern Pine) around 500grain with 125grain field point, going from 28″ to 25″ BOP.

              25grain more point weight (without shortening the arrow) or shortening the arrow by 1″ (with same point weight) produced 1% more FOC (until a certain point which I don’t remember).

              It also depends on the weight of the shaft. So it could be more or less then I found.

                    Would it make sense to build inserts out of a tougher/stronger material (i.e. steel)?

                        Troy,

                        I know and will do like you said. Just wanted to get an imagination if 360grain up front might be possible with this combo.
