Abstract
A movable control stick is urged by springs toward a neutral position. A radio signal generated responsive to displacement of the control stick is transmitted to a remote element to be controlled. The remote element is displaced responsive to the radio signal. The neutral position of the control stick is moved to the position of the control stick at the time a discrete trim command is given. The control stick is urged toward the neutral position by a pair of lever arms, a first pin attached to the control stick and disposed between the lever arms, a second pin attached to a normally latched, rotatable member and disposed between the lever arms, and the spring extending between the lever arms. Responsive to the trim command, the rotatable member is unlatched to drive the second pin toward the first pin.
