Had a good look at plane-ing this fall...bow 65Lb ...444 arrows ...125 gr heads...4" fletch -extreme offset
My G5 strikers 125gr 1/1/8 cut fixed.... flu like field points out to 90 yds ...thought I would try the G5 Magnums 125gr also..with a huge 1 1/2 inch cut fixed blade...
again flew like feild points out to 40 yards...than they started to plane after 40 yds..wildly
Im quite sure I could have tuned them to fly if I had the time ...but it was weeks away from hunting season and I didnt have time...
Point is same weight, arrow, length etc...more blade surface resulted in a plane...
