Abstract: A rotatable release mechanism mounted to an output shaft of a servo/mechanical device and connected to a transport device. The mechanism has at least one wheel with at least one opening that is in communication with a slot that extends to an outer perimeter of the wheel. The opening receives and retains a connecting device during transport and releases the connecting device upon rotation of the release mechanism.

Abstract: A mobile, radio-controlled (RC) airplane flies around an airport in a random pattern, as controlled by an operator with a range greater than needed to scare away birds from runways. The RC airplane includes a receiver to control the launching of a special purpose cracker cartridge having a capsule which burns with a faint smoke trail for a predetermined period of time, after which the projected capsule explodes with a brilliant flash, loud noise, and a small cloud of smoke. By this technique, birds are actually chased out of the path of a runway at an airport. Further, this device can be used to scare birds from agricultural areas, as well as in military training exercises to simulate return fire from attacking aircraft or for use as scare shells during military or paramilitary field training. The cannon firing mechanism which launches the exploding capsule is controlled by a manually operated transmitter from the ground.
