In 2009, a shooting machine that releases the same way every time, a 44.8 lb bow and 29-inch Easton A/C/E 470 shafts: one metre from the bow the bare shaft leaves at 215.65 feet per second, the two spin-wings at 215.1 and 214.4, the two Tite Flights at 212.5 and 212.4. Between the bare shaft and the slowest vane there is about 1.5%, within the same type the smaller vane is a few tenths faster, and the order repeats exactly with two different strings. In 2020 a 48 lb wooden bow on a mechanical device shoots wooden arrows with feathers and vanes of five sizes, and at launch the speeds fall between 42.66 and 43.73 metres per second; over the next 5 metres, however, the energy lost ranges from 1.92 to 7.90%. Fletching therefore changes the arrow's launch only slightly and what happens to it afterwards a great deal. Neither test reports any statistics, the first is a conference paper with no stated number of shots and in the second the arrows do not all weigh the same.claim:alette-velocita-uscita:revision:2026-08-15:2Sat, 15 Aug 2026 08:00:00 GMT https://matteocampagna.com/en/registry/equipment/vanes-arrow-launch-speedclaim:alette-velocita-uscita:new_claim:2026-07-06:riportatoMon, 06 Jul 2026 08:00:00 GMT
