To get rid of the front tube is not really a goal, unless it is WAY too thick.
A round tube of a given thickness has about ten times the zero AoA drag of a 33% t/c foil of the same thickness.
Leading edges will get smaller again in 2004.
I have flown 7 different prototypes with different leading edge diameters. ALL the kites with the smallest diameters, were the highest preforming. When you walk around the beach, just think, in this case smaller is better.
Snicker at kites with fatter leading edges, because they are old school.
If you take a look at foils from paragliding, you'll see that the leading edge size is usually really huge.
Despite they have the possibility to construct it much thinner - they don't !
They are double surface, that's the difference.
All hang gliding round spars have fairings.
