Abstract: A rotorcraft has a rotor blade having a spar comprising an internal space. A weight system is disposed within the spar and the weight system includes a weight tray having an open top, a weight guide rod connected to the weight tray. The weight guide rod extends in a spanwise direction through an interior of the weight tray and a weight is disposed on the weight guide rod and vertically captured by at least one side wall of the weight tray. The weight guide rod is insertable into the weight tray from a location above the weight tray to restrict longitudinal movement of the weight guide rod relative to the weight tray.
