Brand New FIRENOCK Aerovane 3 arrow vane (100 pcs) Each pack has 100 pcs(Please select 1 out of 12 colors: Clear, White, Black, Red, Pink, Orange, Yellow, Lime, Mint, Green, Blue, Violet. See photo 4 for reference) See Aerovane 3 on youtube (just input " aerovane 3 ") Aerovane™ III is featured with:Improved True owl wing frontal design for virtually no sound fly as Aerovane III is a improved version of Aerovane II and thus it flies quieter than Aerovane II when shotLighter weight than Aerovane II which Aerovane III is 10mm in height or 29% shorter than Aerovane II and weighs only about 5.18 grains or just over 30% lighter than Aerovane II4 different aerodynamics texture zones (0.0402mm, 0.0201mm, 0.0150mm and 0.0005mm) instead of 3 different vertical texture zones on Aerovane IILarger total airfoil surface area than Aerovane II to compensate shorter in height so that Aerovane III can have the same total lift and corresponding spin torque as Aerovane IIIncorporation of winglet to improve aerodynamics and further reduce induced drag by wind130% higher effectiveness against crosswind than Aerovane II (e.g. Arrow with Aerovane III should hit a target under 35 mph crosswind at 35 yards with archery projectile at 320 fps as compared to Aerovane II under 25 mph crosswind at 35 yards with the same projectile)350% higher AEM factor than that of Aerovane II (i.e. Higher AEM = Better ability against the attack of wind. The mechanism is that when the arrow with Aerovane is rotating, the frontal section of Aerovane will bend towards the center of rotation while the tail section will bend away from the center of rotation which results in an most effective angle to encounter attack of the wind) Specification of Aerovane II vs Aerovane III Aerovane IIAerovane IIITrue Owl wing designYesYesMicro-texturing zones3 (vertical)4 (aerodynamic)Air foil surface areaStandard129% of StandardTotal lift powerSameAgainst cross wind abilityStandard130% of StandardAEM factorStandard350% of StandardHeight0.55”0.39”LengthSame (1.967”)Weight6.48 grain5.18 grain Notes:Aerovane III should be fletched straight to function.Aerovane III should be fletched with Aerovane Jig and Aerovane Clamp.Aerovane III works best with bow with close to perfect nock travel.Aerovane III cannot work with worn out Whisker Biscuit arrow rest.Aerovane III has a higher broadhead requirement than Aerovane II due to Aerovane III has having a much higher rotational lift (spin rate) than Aerovane II especially when shooting with high speed arrows.
