ABSTRACT:
A stunt kite comprising a first horizontal spar member, a second vertical spline member, third and fourth diagonal spar members, the members being formed into a fixed frame, a covering disposed on the frame and having a lateral dimension which is greater than its dimension corresponding to its longitudinal axis and being symmetrical in shape about the longitudinal axis, a bow string forming the first member into a bowed shape such that the covering is bowed into a generally convex configuration, a pair of bridles each symmetrically connected between the third and fourth members on opposed sides of the second member and extending outside the covering, the substantial midpoint of each bridle forming an attachment point which lies a predetermined distance above the center of gravity of the kite, and first and second tails connected to the bottom ends of the third and fourth members, respectively, for providing substantially equal stabilizing drag forces at the bottom corners of the covering, such that when lengths of line are connected to the attachment points the flight pattern of the kite is capable of being precisely controlled.
