2. SHUTTLE
2.1 The shuttle shall be made of natural and / or synthetic materials. From whatever material the shuttle is made,
the flight characteristics generally shall be similar to those produced by a natural feathered shuttle with a cork
base covered by a thin layer of leather.
2.2 Feathered Shuttle
2.2.1 The shuttle shall have 16 feathers fixed in the base.
2.2.2 The feathers shall have a uniform length between 62 mm to 70 mm when measured from the tip to the
top of the base.

feathers, a variation of up to 10 per cent shall be acceptable.
2.4 Subject to there being no variation in the general design, speed and flight of the shuttle, modifications in the
above specifications may be made with the approval of the Member Association concerned, in places where
atmospheric conditions due to either altitude or climate make the standard shuttle unsuitable.

boundary line. The shuttle shall be hit at an upward angle and in a direction parallel to the side lines.
