A rotor assembly (100) comprises a rotor hub (104) and rotor-blade assemblies (112). The rotor hub (104) comprises rotor-blade supports (108). Each rotor-blade assembly is coupled to a respective one of the rotor-blade supports (108) and comprises a flap axle (114), a hub connector (116), a rotor blade (120), and a torsion strap (122). The flap axle (114) extends through a respective one of the rotor-blade supports (108) and has a central flap-axle axis (110). The hub connector (116) is pivotable relative to a rotor-blade support about the central flap-axle axis (110) and defines a central hub-connector axis (118). The rotor blade (120) is coupled to and is pivotable relative to the hub connector (116), and, together with the hub connector (116), is pivotable relative to a respective one of the rotor-blade supports (108) about the central flap-axle axis (110). The torsion strap (122) has a first end (124), coupled to the rotor blade (120), and a second end (126), through which the flap axle (114) passes.
