A system of adjustable balancing weights is provided for a helicopter main rotor blade (42). The trailing edge (52) of the rotor blade (42) is formed with a plurality of recesses (74) that each receive an aerodynamically shaped weight (92,92') to adjust and balance the weight of the rotor blade (42). A forward weight recess (64) and a forward weight (68) are also provided on the rotor blade (42) adjacent the rotor blade leading edge (48). The lateral spacing between the weight (68) adjacent the rotor blade leading edge (48) and the weights (92,92') adjacent the rotor blade trailing edge (52) provides greater flexibility in balancing the mass of the rotor blade (42).
