While conceptually possible, picking apart a kite and duplicating the components is practically impossible, especially the canopy which is to some extent elastic. It would require a sophisticated workshop and a very time consuming and precise process. And, copies can never be better than the original, even when accurately done. At best, one would be at a starting point to embark on further development without knowing how the kite got to it's present state and what was done to get there. Though the Nitro6 looks essentially the same as the Nitro5, it is entirely different and nearly every seam was modified to reshape the canopy and revise the LE tube. This work was all done outside of a CAD environment using hard-earned experience with traditional sailmaking techniques and previous testing to achieve the desired improvements. Unless an entirely new design was generated with CAD software, a Nitro7 would require a similar effort.
Why is it impossible?
Put it this way, what are the canopy tolerances for any kite out of the factory? Are the tolerances in 1/10 of mm? 1mm?
If the tolerances are not that strict, and I can't see it as that strict, a few mm (cm?) would not matter that much.
Also, when I think of the kite, the black fabric is probably expanding due to a heat much more than bright fabric.
Do we know how much is expanding (due to tension as well), and how much are the tolerances relevant in this scenario? The Flysurfer is claiming that the kite is based on pre-stretched calculations somehow, so maybe that is 'built in' the kite.
I think for an DIY it is possible to make 'exact' copy, providing the expectations for such kite are adjusted.
