Japanese researchers are studying the design for a multicopter electric vertical-takeoff-and-landing (eVTOL) air taxi that uses the lift-offset rotor concept to improve aerodynamic efficiency in the cruise phase of flight. Development of the multirotor lift offset (MRLO) concept was begun in 2023 by...
