While they appear fragile, butterflies are amazingly strong. Robert Brasington has tried to replicate these traits in his Butterfly kite. The kite looks to be delicate but is a strong flyer, able to handle a wide range of wind conditions. The almost weightless 9-ft. organza tails make it a steady flier in 4 to 18 mph winds. Made of ripstop nylon with fiberglass spars. 5’-9” x 2’-3”. 40” case. Use 50-lb. Dacron line.
