The concept makes use of four pairs of co-rotating propellers that provide vertical lift. Once at cruising altitude, the concept reverts to more efficient fixed-wing operation with a single rear rotor providing thrust.
Pipistrel is a Slovenian light aircraft manufacturer with a very different take on the eVTOL concept. Its craft, shown here in cruising configuration, is designed around speed and stability. The VTOL hardware is hidden away in this configuration.
