Embodiments may provide a kite system that incorporates a highly efficient lifting surface combined with aerodynamic control surfaces while using only a single tether. Such a kite having a lifting surface combined with aerodynamic control surfaces while using only a single tether may be referred to as a 'controllable kite'. Embodiments may include a controllable kite configured to operate aloft connected to only a single tether, the kite including a lifting surface that is heavier-than-air, an aerodynamic surface control system configured to adjust an attitude of the lifting surface while the kite is aloft, and an attachment point connecting the single tether to the kite.
