I think Bille on other older threads was after rigid kite, like "rigid wing hang glider" so I interpret his statements on this background that VMG2 must be rigid. And I answered in this thread for Bille on this background that what if kite design is that kite must be flexible to allow it turn properly. Also lesser point load from batten to fabric so that fabric will last longer. etc. There could be lot of other reasons than "being cheap" for selecting more flexible material.
YES -- your mostly correct on that ; but i would never start a debate
over aerodynamics , because the choices made are mostly subjective .
Like with Hang gliders, we have weight shift control, which must be
very flexible skin airfoils or they don't work, and rigid-wing airfoils
that need devises like spoilers to turn , (I fly , and enjoy -- BOTH) !!
My original question for choice of materials for the battens, was only
meant for, (curiosity) ; it certainly wasn't meant to deliberately get people
Heated.
As you know , i build my own fake legs , so if there is a combination
of composites that are specialty used ; then it peaks my interest immediately.
Walking with 30g of extra weight , over 18 holes of disk golf ; can make the
difference between being tired , or Really tired , because i exert about 25 to
35% more energy than a guy using their stock god given legs, every time
i walk.
