The comparison table that @Mighty Mouse posted showing a 5-8FPS loss at 80 yds is interesting...based on the comments, I was expecting it to be much worse.

Hardly at all. As mentioned previously in this thread, 3 degrees on a 4 fletch was averaging about 5 fps difference at 80 vs a 3 fletch. I believe what Bill was referring to was a weight difference. 3 Max hunters is 21 grains vs 4 Stealth is around 32-36.I’ve never had a reason to shoot a 4 fletch, so I don’t know how much it would affect the velocity.
Straight offset on the RaptX or helical? Planning on doing the same with the RIP TKOs I got coming today.I shoot 4 fletch Rapt X, Blazers, and TAC Summits. At first I did it just for weight because I was out of wraps. Kyle Douglas also shoots 4 Rapt X on both his hunting setup, and most of his target arrows. I shot Tac out to 100 yards without any issue with the number 15 Spot Hogg tape. If I had to guess the offset I'd say it's probably 2 degrees.

I was wondering the same thing...how much of the 3-vs-4 fletch trajectory/speed difference can be attributed to the extra weight vs the extra drag? 11-15 gr doesn't seem like much, but at very long ranges it might have a significant effect on drop.I believe what Bill was referring to was a weight difference. 3 Max hunters is 21 grains vs 4 Stealth is around 32-36.
Kyle Douglas shoots 2-3 degrees on his.Straight offset on the RaptX or helical? Planning on doing the same with the RIP TKOs I got coming today.
Out to 40 yards with the same vanes 4 fletch 3 degree RH vs 3 fletch 2.5 RH with arrows of the same weight, or even the same weight the difference in point of impact is nada. Unless a guy can shoot Robin Hoods one after the other he is not going to be able to tell the difference accuracy wise anyway.I recently switched to 4 vane arrows and have noticed a speed decrease but not necessarily an accuracy/flight improvement.
Is there any merit to more and longer vanes increasing drag etc? I mean I'm sure it has an effect but is it enough to be concerned with?
3 from 80 with the rapt-x 4 fletch straight offset. Maybe a bit steeper pitch than yours, might back it off a little. Did fletch up a few with a 3 fletch helical to compare. 4 fletch shoots great though.I switch vanes more than anyone I know lol. It’s a problem. Last year I ran 3 blazer type vanes in a 3 degree helical. They shoot good and control BHs.
Lately I’ve been testing 4 fletch blazers. I too have said 4 fletch blazers is way overkill! However here I am testing it. I fletched them with about 1 degree offset. At longer yardages they seem to hit same with the 3 fletch. The 4 fletch seem to be more forgiving.
Here was amazing tightgroup i shot at 115. The one arrow flys low everytime. I need to weigh it or check it because it consistently shoots low. But the point of the pic is that the 4 fletch groups same with the 3 even at 115 yards. Obviously the 3 fletch shoot great. And if I do my part they do but if I don’t it seems the added vane of the 4 fletch is more forgiving
Nice shooting3 from 80 with the rapt-x 4 fletch straight offset. Maybe a bit steeper pitch than yours, might back it off a little. Did fletch up a few with a 3 fletch helical to compare. 4 fletch shoots great though.
