A controllable variable twist rotor blade assembly wherein the twist along the span of the blade is continuously variable and may be controlled either manually by the pilot or automatically according to data input from flight sensors monitoring flight parameter data. The continuously variable twist of the blade is controlled by an out-of-plane weight assembly having a weight member which is selectively movable between a first position and a second position relative to the elastic axis of the blade so as to optimize the twist of the blade during various flight conditions.
