A kite has a generally delta shaped sail and supporting frame and has increased flight stability through locally increased drag realized by providing an air-passing ring structure in a plane adjacent the kite sail. The ring structure is formed from continued extents of the kite sail extending rearwardly of the sail trailing edge, folded up into the ring structure.
