This invention relates to a new model plastic shuttlecock which composed of a round tail skirt without undulation and a mid-skirt zone with some reinforcing circles and stems of pyramidal section, which offers appropriate strength of its tail skirt. And there are two rows of air resistant surfaces which are extended from the end of the tail skirt towards the mid-skirt zone and the inner side of the feather wings. The air exhaust surfaces have many larger net shaped air stream outlets to make the shuttlecock rotate and balance the air pressure difference between the inner and outer sides of the feather wings increasing the accuracy and stability of stroke and flight of the shuttlecock and also preventing its swinging to and fro during flight.
An improved shuttlecock for use in a badminton game is provided with a cork cap and a cone-shaped skirt which is provided with a plurality of evenly spaced stems. The stems diverges from a top end having a collar tube having more than one securing flange for securedly mounting the goal cap. A pair of integrally formed reinforcement hoops secure the stems together with a plurality of circular rings of different sizes parallelly extending downwardly from the lowerest hoop to the bottom of the skirt. A feather-like wing portion divided by a stem into left and right wing portions has a triangular wing tail. A partition area is disposed between two of the wing portions. Each left wing portion has a plurality of parallel slanted strands extending in an angle from each stem from right to left and right wing portion also has a plurality of parallel slanted strands extending in an angle from left to right from each stem. A plurality of holes form in the left wing portion and the right wing portion with the density of the former larger than the latter. The ration of the horizontal width of the left wing portion to the right wing portion is approximately 2:1.
