A rotor kite is characterized by a stabilizer bar connected between the wing and stabilizer ring components of the kite to maintain the wing and the stabilizer ring in a perpendicular orientation with respect to each other during flight. The stabilizer bar is connected at its ends with the inner edge of the annular stabilizer ring so that the bar extends across the inner diameter of the ring. The wing is connected with the bar at multiple locations within the stabilizer ring, with the bar extending normal to the longitudinal axis of the wing. When the kite is released, the wind rotates the wing which in turn lifts the kite into the air. The stabilizer acts as a rudder to maintain the wing perpendicular to the wind direction.
