TORC (Torque Operated Rotor Control)
Aircraft using TORC technology benefit from having rotatable motors and variable pitch blades without the need for actuators or complex mechanisms.
Rotor orientation and blade pitch are controlled by rotor torque...
Motor direction is changed to go from vertical to horizontal flight.
Simpler configurations may use a bidirectional propeller to accommodate motor reversal.
