Abstract: A transmitter for a radio control system capable of highly facilitating the changing-over operation and constantly exhibiting desired control characteristics. The transmitter includes a plurality of main control elements which are controllable in directions relative to each other about a neutral point and control basic operation of a controlled unit, an auxiliary control element for selecting control characteristics of the main control elements, a first changeover element for changing over mechanically neutral of the main control elements, and a second changeover element operated when specific control characteristics of the main control elements are selected by the auxiliary control element, resulting in setting an electrically neutral point of an actuation section depending on the mechanically neutral point of the main control elements. The operation of the first changeover element causes the second changeover element to be changed over in association therewith.
