Abstract: A convertible helicopter ring member includes a ring member and a drive mechanism. The drive mechanism orients the ring member substantially in-plane with a tail rotor of a helicopter during a first mode of helicopter operation and orients the ring member substantially off-plane with the tail rotor of the helicopter during a second mode of helicopter operation that is different from the first mode.
