A rotor hub fairing system (36) for use in a counter-rotating, coaxial rotor system (12) is provided including an upper hub fairing (38) defined about an axis and a lower hub fairing (40) defined about the axis. A shaft fairing (42) is disposed between the upper hub fairing (38) and the lower hub fairing (40). The geometry of the shaft fairing (42) is configured to encourage a wake adjacent the upper hub fairing (38) to form collectively with a wake adjacent the lower hub fairing (40).
