ABSTRACT:
A saucer-shaped aerial toy has an on-board signaling device actuated only during flight by the closing of a pair of centrifugally-actuated electrical switches. The on-board signalling device may generate sound and/or light which not only have recreational value, but also serve as early warning indicators that the aerial toy is in the vicinity.
