ABSTRACT:
A kite of the swallowtail sled type, comprising a central panel, or canopy of light-weight sheet material, such as paper or thin plastic film, generally in a rectangular shape. It has two long parallel sides, with shorter leading and trailing edges. The leading edge is similar to a shallow isosceles triangle. The trailing edge is cut away also in the form of an isosceles triangle but with the height of the triangle greater than that of the leading edge. Two triangular lateral panels are attached, one to each of the sides of the central panel. At least three slender stiffening battens are attached, one to each of the long sides of the central canopy and one along the center line. A tension cord means or halter, shorter than the width of the central panel is tied between the trailing ends of the two battens.
