Abstract
A controller for producing electrical control signals has a relatively stationary supporting section providing an upwardly facing hand supporting surface and an upward projection, and has a stick-like control section mounted on a first gimbal joint on top of the projection, to swing about pitch and roll axes. A second gimbal joint is spaced along the roll axis from the first one and rotates about said roll axis and about a gimbal axis parallel to the pitch axis. A gimbal ring of the first joint is rigidly connected to a gimbal member of the second joint for unison rotation about the roll axis. A second gimbal member of the second joint is caused to rotate about said gimbal axis in unison with swinging of the control section about the pitch axis by a linkage connection between them. A signal generator for each of the pitch and roll axes and a stick force generating means for each of those axes are connected with respective gimbal members of the second joint.
