The Yonex Aero Club 03 is a new line of shuttlecock for 2009. The shuttlecock is similar to Aerosensa 10 (AS-10) using mixed feathers to create a good durable and smooth flying shuttlecock. The shuttlecock is targeted for club / practice grade. Durability is claimed to be similar to AS-10.

Accurate distance stability
YONEX Feather Shuttlecocks demonstrate accurate flight stability over distance under varying environmental conditions. In factory testing, YONEX AS-30 and other brands in the same price range were machine fired downcourt under identical stroke and distance conditions. AS-30 demonstrated consistently stable flight performance in these tests-with 71 percent of the AS-30 shots hitting the target, compared with 58 percent and 17 percent for feather shuttlecocks of other make.

Built to deliver a lower frequency of replacement during play From the careful selection of high-quality materials through to each advanced manufacturing process, meticulous attention to detail goes into the design and production of YONEX Feather Shuttlecocks to ensure distance stability under the varying environmental conditions of international play. Quality to withstand the punishing impacts of today's high-speed game is why YONEX Feather Shuttlecocks are the official shuttlecocks of leading international tournaments and the reason YONEX Feather Shuttlecocks require less-frequent replacement during play than ordinary feather shuttlecocks.
