Dudu, Jamie and Renata tested two Rokkaku kites today, both with inflatable cuben fiber struts. Kite A was the best one from Friday (#4), which had 50% of the original curvature, 90% of the original diameter, and long battens. Kite B was a new one with the same tube diameter, 75% of the original curvature, and short battens.
Both kites flew well with the same stability and held all gusts with no issue. The 50% kite still had better flying angle.
This test proved we can have smaller battens at strut tube tips and still spread the loads. This can save weight and storage.
