And here I thought the most important part was at the end of the flight, when the arrow was losing velocity and fighting the wind. Learn something new every day.If the wall of the straw is too thick, it's not going to work very well. Most of the work is done at the first few feet of the arrow leaving the string. If it doesn't unfurl during that short period, it's not doing its job.
The battle is fought before the dive. That’s coasting, like the Apollo missions where the rockets fire the first half that decides how the rest of the journey plays out. The last dive only requires minimal drag from the curled vanes attached to a shaft rotating at the rate decided by the instantaneous velocity of the arrow and the effective pitch to achieve net zero angle of attack of the three vanes. The reason spinnies work the way they seem to work is because of its ability to achieve maximum drag at zero rotation and transit to minimal drag. It is not as effective as straight vanes or feathers in changing wind conditions through the flight pat to the target but it more than compensated by doing its job better than the straight vanes both at the beginning and at the end.And here I thought the most important part was at the end of the flight, when the arrow was losing velocity and fighting the wind.

Hi, I will try to shoot them and compare with spinwings once I get the chance to go on the range. Maybe on the weekend. But I think I don't shoot good enough to show differences caused by the vanes. Lol. I'm putting it here so maybe the better shooters can test them out. Hehe.Cool, does your 'little experiment' include shooting arrows with any of these straw-vanes on them? If so, how do they perform? If not, why don't you? - John
Actually, I have to (and hate to) agree with TMD on this one. The only ones who worry/think/tinker over this stuff are the amateurs. I'm not saying it isn't worth doing. Quite the contrary. But the "good" shooters spend a lot more time training, and not a lot of time tinkering, as they are usually sponsored or are inclined to just go with what they know works for other good shooters.The good shooters or even the pros might also want the idea of being able to custom cut the profile and angle of their spin vanes? I imagine there would be different optimum profiles and angles for different setups because of different draw weights for example.
Maybe they could sell us range o matic, xswings or gas pro "straws" and let us decide the best angle and shape for our vanes.
