A rotor assembly for a rotary wing aircraft includes a rotor hub having a central axis, the rotor hub rotatable about the central axis. A plurality of flexible structural members extend radially outwardly from the rotor hub, each flexible structural member substantially U-shaped and having a first arm extending from the hub, a second arm extending from the hub, and an end portion connecting the first arm to the second arm at a radially outboard end of the flexible structural member. A clamp member is positioned between the first arm and the second arm of each structural member and secured thereto to tie deflection of the first arm to deflection of the second arm. A rotor blade is secured to each flexible structural member of the plurality of flexible structural members via the clamp member.
