About Overair

Overair is a Santa Ana, California eVTOL developer that spun out of Karem Aircraft in 2020. Its flagship aircraft is the Butterfly — a piloted, six-seat (1 pilot + 5 passengers) tilt-rotor eVTOL using Karem’s Optimum Speed Tilt Rotor (OSTR) technology, originally developed for the US Defense Advanced Research Projects Agency.

OSTR varies rotor RPM in flight to keep blade-tip speeds in the most efficient and quietest band, giving the Butterfly a target range and noise profile competitive with the best of the urban air taxi field.
