A remotely controllable toy surface vehicle has the capability of deploying wings on command and to attain flight in the absence of any air interactive propulsion mechanism. In an alternate embodiment of the invention, the fixed wings are first pitched to keep the vehicle on the ground or water until a takeoff velocity is reached; after which the pitch of the wings is remotely adjusted for takeoff and flight.

[ What is claimed is:] [1.]1. A vehicle operable over a support surface which comprises:propulsion means interacting with said support surface, said propulsion means being empowered to impart upon said vehicle, a given surface velocity;means interactable with ambient air for lifting said vehicle at said given surface velocity and causing said vehicle to be temporarily airborne in the absence of any air propulsion means; andwherein said means for lifting comprises a variable geometry wing including a foldable and deployable airfoil, and means for remotely deploying said airfoil when said given surface velocity has been reached; andwherein said airfoil comprises:two leading edge booms each rotatively connected to a central pivot point;at least one membrane secured to said booms; andmeans for resiliently biasing said means for deploying toward an extended state.
