At this time, the Sting VTOL is little more than an artistic concept; not much more information is available on this VTOL at this time.
Stage of Development
No technical details are available at this time. From the art concepts posted online, it appears that the Sting VTOL would utilize gas turbines that drive the fans in the Blended Wing Body (BWB) of the aircraft.
