Abstract: An improved propeller system is disclosed, including at least one resilient component configured with a mounting arrangement of a propeller of the propeller system. The resilient component is made of a resilient material that allows the propeller to tilt about a tethering axis under conditions of differential lift force on blades of the propeller under an advancing condition and a retreating condition. The resilient component includes a pair of cutouts for locating inserts made of a rigid material and positioned with a longitudinal axis of the inserts oriented in radial direction. The orientation of the inserts results in a radially oriented line contact between the propeller and the inserts to ensure that tilting of the propeller is about longitudinal axis of the inserts, defining the tethering axis of the propeller system.
