The model took off in front of Federal Aviation Administration officials to obtain flight authorization certificates. According to Evtol.com, testing of the SN3 version is expected to take place soon in the skies of Japan. Weighing just over 567 kg, the Mk-5 looks more like a cross between an airplane and a helicopter than an eVTOL itself speaking. With a total of 33 propellers distributed in the biplane structure, only one of them at the rear is responsible for thrust on the horizontal axis. The other 32, divided into 8 rotor shafts, support the aircraft vertically.
