Wall racer toy vehicles

Toy vehicle with remote control, battery powered and can operate on a vertical surface, comprising: - a chassis (12, 60, 40) having a bottom surface (12b, 12c); - At least three wheels (16, 18, 62, 64, 42) mounted on said chassis (12, 40, 60) for supporting said frame (12, 60, 40) relative to a substantially flat surface against which abut said wheels so that the bottom surface (12b, 12c) of said chassis is maintained at a predetermined distance from said surface; - A radio (26) responsive to a control signal emitted by a remote transmitter; ; - A first motor (24) receiving the drive current of said battery (26) and responds to the signals provided by said radio receiver (26) - a battery (26) - Being driven controllably least one of said wheels (16, 18, 42, 62, 64) by said first drive motor (24); - A second motor for driving the fan (39) which also receives the current from a battery, and - a fan (10) driven by said second motor (39), said fan (10) being mounted in a fan duct (46 ) that spans across said chassis and disposed generally orthogonally relative to said surface in order to aspirate an air flow from the space between said lower surface of said chassis and said surface, characterized in that said lower surface of said chassis is designed so that the vehicle is placed on a surface with said at least three wheels in contact with said surface defining said bottom surface and said surface together a duct venturi under the body, through venturi extends under the body from an inlet section in the periphery of said undersurface to said fan duct inducing the differential pressure between said stream of air flowing in said venturi passage under the body, and the ambient air one forcing downward force said frame to said flat surface.
