A badminton shuttle comprises a base 11 and a plastics conical skirt 18. The skirt 18 comprises, at its narrower end adjacent the base 11, a stem portion (10, figure 1) formed of a plurality of longitudinally extending stems 16 and, at its wide end, a flight portion (14, figure 1) within which a web 18 extends between the individual stems 16 to increase the aerodynamic drag on the shuttle. The skirt 18 includes a plurality of circumferentially extending annular ribs 20, 22 or 24 interconnecting the stems 16 both in the stem portion (10) and in the flight portion (14), the cross section of which ribs is dished or angled to increase the resistance of the annular rib to radial deformation. |
