  • Patent number: 4421485
    Abstract: To control a model aircraft or spacecraft with a control stick, the first and second sides of a parallelogram linkage within the console housing are attached to and form universal joints for the bottoms of a control column and control stick respectively, both of which extend out of the console housing, with the craft being mounted to the control column. Both the control stick and the control column are mounted by universal joints to the console so that movement of the control stick causes swiveling and tilting motion of the craft in both forward and side to side directions and any position in between about the universal joint under the control of the parallelogram linkage which connects the bottom ends of the control stick and control column.
