California-based eVTOL company. Parent company is Karem Aircraft, which has decades of experience working on tilt-rotors and rotorcraft for the US Military. Overair's aircraft design is the Butterfly, a 5-seat vectored thrust transitioning eVTOL that features some of the largest diameter props in the class, with individually controllable pitch on each blade.
eVTOLs are one of those things that many groups announce their plans to create, but fail to produce in physical form. Such is not the case with Overair's Butterfly, however, the just-unveiled prototype of which should soon begin flight testing.
California's Overair eVTOL is taking virtually the opposite approach to Germany's Lilium, with two of the biggest props you'll see anywhere in the class and individually pitch-controllable blades that'll unlock some unique capabilities.
