Abstract: An anti-torque assembly for a helicopter includes a plurality of fans pivotably mountable to a tail boom. The fans have fan blades rotatable about a fan axis. One or more of the fans is pivotable relative to the tail boom to a first configuration. The fan axes in the first configuration have an upright orientation and the fans are operable to one or both of pitch and roll the helicopter. Different fans are operable to generate thrust to provide anti-torque to the helicopter. A method of providing anti-torque and method of changing an attitude of a helicopter are also provided.
