Abstract: A footing connector has a first hollow leg and a second hollow leg integral therewith. The interiors of the two hollow legs are in fluid communication. The two legs cooperate to form, preferably, a T-shaped connector. The first leg has threading thereon, and, preferably, the second leg has threading thereon and protruberances therein, to enable connection to other elements of a drainage system. The second hollow leg may have end caps integral therewith at the ends thereof. The connector is used in a drainage network to drain water away from the outside of a building and to evacuate unwanted gasses from the inside of a building.

Abstract: A radio controlled aerial disc capable of flight in any direction when airborne. The invention provides upper and lower body portions which form a disc shaped housing when connected. Within the housing there is a servo motor and drive assembly coupled to a quadripartite blade to provide lift and motion to the aerial disc. A servo control mechanism and a rear prop assembly are also components of the invention for controlling the movement of the aerial disc. A receiver mounted on the aerial disc provides a method of receiving signals from a remote transmitter to control the movement of the aerial disc.
