  • Patent number: 4162582
    Abstract: A small model of an aircraft is provided in which the operator is seated in the cockpit. The primary flight controls are selectively operable and actuate six variable speed transformers through the movement of control cables operated by the respective flight controls. The amount of current provided by the transformer outputs is directly proportionate to the degree of control movement. The current is used to activate small, variable speed, reversible electric motors which in turn operate rollers set in pairs and aligned on opposite sides in the three primary planes of rotation of a freely movable sphere contained in the forward aircraft housing. In accordance with the forces imparted to the three different controls, movement is transmitted to the sphere. The sphere itself has included within it a plurality of slide projector units each of which will display or project on a single reflective screen a picture of its own particular portion of the sky or ground.
