Below there is an interesting example of scaling by size (from Barnard's predictions ) :
For what I remember Mothra1 is an arch of 300 m². As this kite contains several elements it can be seen also as Scaling in numbers rather than size , even as a kind of Kite Networks.
I don’t know the conditions of this test. With a wind speed of 10 m/s, the force could be quite huge, several tons when the kite accelerates by rising.
With some first changes (adding a winch and a generator) and some research (depower for recovery phase) it could work as a yoyo system.
