A multi-axial hand-operated helicopter control includes a pivotal arm which may freely pivot in two planes relative to a base member with collective and rudder control rods attached at the base of the pivoting arm member for translating motion along one plane into collective control and motion along another plane into rudder control. A rotatable throttle control mounts at an end of the arm member and a throttle shaft extends through the arm member attaching to a constant velocity joint for translating rotational movement of the throttle control into rotational movement of a base throttle rod. The pivotal arm member is mounted to a base member via a universal joint, with the constant velocity joint placed at the center of the universal joint, achieving high torque rotation. A method of operating a helicopter in accordance with the invention includes controlling the helicopter collective via movement of the control arm in a vertical plane, controlling the rudder of the helicopter through movement of the control arm in a horizontal plane and adjusting the engine throttle via a throttle handle mounted on the arm member. Foot controls for the helicopter are eliminated.
