PTERO (Passive Tilt Electric Rotor) Technology

Airframe and rotors are passively positioned by differential thrust, gravity and relative wind. No servos, tilt mechanisms or control surfaces required.

TORC (Torque Operated Rotor Control) Technology

TORC technology provides tiltable rotors and variable pitch blades without requiring actuators, linkages or other complex mechanisms.

Rotor orientation and blade pitch are controlled by rotor torque. Motor direction is reversed to go from vertical to horizontal flight modes. Simpler configurations use a bidirectional propeller.

SCOPIC Technology - In Development

SCOPIC technology is the final solution for every application involving a spinning propeller blade or rotary wing. SCOPIC technology will replace every current propulsion system by providing collective and/or cyclic pitch control to any system without using actuators, swashplates or other complex mechanisms...
