A frisbee disk and ball drop assembly comprising a circular frisbee disk having a convex outer wall and an inner concave wall, and a ball drop assembly carried on the wall of the frisbee disk at its center for dropping a ball from the concave wall of the disk when in flight on command from a remote control transmitter operated by a person on the ground. An object is to see how close the ball can be dropped to a preselected target on the groung. The ball drop assembly includes a loading and discharge tube to carry a ball to be dropped therefrom, a pivotally mounted gate pivotable between an open and closed position to open and close the discharge aperture of the loading and discharge tube, an operating mechanism to pivot the gate between its open and closed positions, a power source to drive the operating mechanism, a control circuit to start and stop the power source and a receiver to receive a sound wave or radio wave signal from a remote transmitter and to energize the control circuit upon receipt of such signal. A convenient power source is one or more small dry cell batteries to power a small electric motor for driving the operating mechanism that opens and closes the discharge tube gate. A convenient control circuit includes solid state components such as an integrated circuit or discrete transistors with associated resistors and capacitors to provide amplified electrical power to operate the motor upon receipt of a signal from the sound wave or radio wave receiver. The components may be embedded in the wall of the frisbee disk.
