Noticed kites of different makes seem to have very similar sail shapes.
Especially today after flying for the first time a Vendetta, which has been lent to me by a very generous person, I couldn't help myself thinking: where do I know this kite from?
Think now there's an Italian connection:
The Vendetta's form seems to be congruent with that of the Opera.
Furthermore I found the Genesis (LevelOne) has almost identical dimensions like my Mantis.
Looks like by coincident two similar designs have emerged in different parts of the world?
