A helicopter includes a tail rotor, a primary drive system operatively connected to the tail rotor, and a secondary drive system operative connected to the tail rotor. The secondary drive system is configured to supplement torque provided to the tail rotor by the primary drive system. Related tail rotor drive systems and methods of applying torque to tail rotors are also described.
