A rotor-hub flap-measurement system includes a rotor hub operable to flap relative to a rotational axis of a rotor mast. The rotor hub includes a fork driver fixedly coupled to the rotor mast and operable to rotate about the rotational axis, a drive plate operable to rotate about the rotational axis and to rotate out of a plane perpendicular to the rotational axis, out-of-plane rotation indicating flapping of the rotor hub, and a universal joint coupled to the drive plate and comprising a cross, the cross comprising four trunnions equally spaced azimuthally about the rotational axis. The rotor-hub flap-measurement system also includes a magneto-resistive sensor system coupled to the cross and operable to detect rotation of a first trunnion of the four trunnions.
