#1. coaxial configuration allowes the rotors to counter-rotate on the same mast. Because a coax' did not generate torque, no engine power was wasted driving a tail rotor that produced no lift or forward thrust. Doing away with the tail boom, tail rotor drive shaft, gearbox, and other accoutrements also saved considerable weight and reduced drag.
