KiteLabs and kPower really have tried to “test everything” as far as possible, while keeping many complex scaling factors in mind. This required working very small and fast, compared to typical players who hastily down-select architectures to scale up. Even working small, one can definitely detect critical scaling barriers by the slight loss of performance between a smaller and larger prototype.
As AWE R&D continues, count on kPower to continue to seek the broadest testing experience of any AWE player, across all known architectures, and even at large scale (giant kites). Mothra1, at least, was a >300m2 wing, and Mothra3 is >120m2, to study large-scale operational design.
