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. 

At the moment the only information on a tube of shuttles is the speed and there is no recognized standard for this. In a sport where the characteristics of the projectile is fundamental this is ridiculous.
We at Bird Design are working on some simple tests to set a standard. Weight and size are already defined. Final spin rate and rate of spin acceleration need to be defined. Porosity of the skirt is easy to measure. Rigidity of the skirt is easy to measure. Grip on the racket face can be measured. Flight parabola (peak and drop) is less easy to measure but is a function of the value of all the other attributes.
Any inputs to this work would be welcomed.
