    Abstract: The vehicle includes a fuselage; a plurality of lifting surfaces attached to the fuselage having control devices attached thereto; and, an articulated propulsion system attached to the fuselage. The propulsion system includes a duct assembly pivotally connected to the fuselage. The duct assembly includes a duct and a propeller assembly mounted within the duct. A motor assembly is connected to the propeller assembly. The duct assembly may be positioned in a substantially vertical position to provide sufficient direct vertical thrust for vertical take-off and landing and may be directed in other positions to provide a varying spectrum of take-off and landing configurations, as well as a substantially horizontal position for high speed horizontal flight. Use of the control surface in the ducted propulsion assembly provides VTOL capability in a very small environment. The environment is not required to be prepared in any special manner. During horizontal flight, the wings provide the lift, which is more efficient than a propeller providing lift. The present invention takes advantage of a center line propulsion, so that there are no asymmetric propulsion loads.

    Abstract: A mobile educational toy which simulates a train has a plurality of toy units which are coupled together to form a train. The toy units each include a mobile carriage structure and a graphic block. The graphic blocks are shaped in the form of an alphabet letter, number, or other symbol. By arranging the toy units in a specified order, words or other relationships can be formed by the user. In addition, by virtue of the coupling together of the toy units, a toy simulating a train is formed.
