While watching a video on how to repair a hole in a bladder it got me to wondering if a kite company has ever attempted a bladder-less kite? I mean we run auto tires without inner tubes. Why not LEI kites?
I realize the current material used on most leading edges are air permeable but I am sure a sealant could be applied to the inside of an LEI that would make it air tight. Or am I completely off base in my thinking?
