Abstract: The present disclosure relates to a coupling assembly (100) for a rotary-wing system (200). The coupling assembly (100) includes a teeter spindle (105), a pair of independent teeter hubs (107), and a pair of needle roller cage assemblies (111). The teeter spindle (105) is coupled to a rotor of a motor (103) mounted on an air frame of the rotary-wing system (200), and is positioned between the rotor and an even-bladed propeller (101), the teeter spindle (105) adapted to be rotated with the rotation of the motor (103). The pair of independent teeter hubs (107) is structurally bridged by the propeller (101) and is coupled with the teeter spindle (105) via a central shaft defining a teeter hinge axis (701). The pair of independent teeter hubs (107) secures the propeller (101), such that the span-wise axis of the propeller (101) physically lags the hinge axis (701) by about 45-degrees. [Figure 1]
