"Flying Flexifoils without a rod."
Not possible? Of course feasible! Jannevan Nederpelt and Jan Pieter Kuil of Vacuum have developed a system which eliminates the rod in the kite's leading edge. The principle is based on rings made from aluminium which slide freely on line bows sewed at the leading edge. Refer to drawing for details. Important: Drawn line lengths are not to scale for reasons of clearness. Compulsory are the measurments. They refer to a 180cm Flexifoil. for larger kites they must be adjusted accordingly. Similar bridle systems work with the Speedfoil and the Paraflex too.
