The control system for attachment to a collective lever in a rotorcraft which comprises a body with an extended horn portion which is generally contoured to provide for a place to rest the palm and grip the collective lever at the end in the form of an open spherical grip as opposed to the more traditional cylindrical grip used to grasp the throttle and/or collective lever directly. The control system generally includes a plurality of controls which can be manipulated by any or all of the four fingers of the hand and the thumb without need to substantially move the palm. The collective lever can also be moved without having to remove the hand from the control system or the fingers or thumb from the controls.
