shuttlecock performance specification

We need much more information on a tube of shuttles. I think the minimum categories should be: Speed; Flight curve (peak & drop);Tumble stability; and Durability.
Speed, flight curve, and tumble stability are all a direct correlated function of the weight and dimensions, surface area continuity, weight distribution from base to tip, spin rate and rigidity. All these attributes can be measured fairly simply in a standard test laboratory in any country. Durability is more difficult as it needs custom made test equipment, although not very complicated.
For now our priority is to complete the funding round for our high volume manufacturing processes and get everything working well for the new badminton season. We will be continuing with this work and would be interested in any comments.
