Aurora Flight Sciences announced on April 25, 2017 that the company is developing an eVTOL aircraft for the Uber Elevate mission. A quarter-scale aircraft was flown with a length and wingspan of 2 m (6.6 ft) and a weight of 12.5 kg (27.6 lb). It uses eight 35.5 cm (14 inch) lifting propellers, and a single 30.5 cm (12 in) cruise propeller. It was designed for a maximum speed of 90 km/h (48.6 kt) and a hover time of 7.0 minutes. The full-scale aircraft as originally envisioned then has a length and wingspan of approximately 8 m (26.2 ft). It has a maximum weight of 800 kg (1760 lb). A 10% scale model was also built and flown with and without the fuselage.

On May 8, 2018, at the second Uber Elevate Summit, Aurora unveiled three design variants that are also being considered.
