A deltoid kite structure configuration incorporates a series of improvements over the conventional Rogallo wing configuration. The present kite structure includes a central keel and separate leading edge members, but the flexible lateral spar is not attached to the keel. This allows the flexible lifting surface to bow upwardly as required, with the leading edge members also moving upwardly and inwardly to relieve aerodynamic gust and other loads. The lateral spar accommodates this movement of the leading edge members by bowing above the keel. Plural lateral spars may be used as required, to tune the flexibility as desired. The lifting surface includes a rearwardly extending portion integral therewith, to provide additional lateral stability for the kite. Advertising or display panels may be removably attached to the kite, and/or electrical lighting may be carried as desired. The central keel may comprise a hollow tube for battery carriage.
