Carter Aviation Technologies has been studying electric-powered aircraft that would fulfill the Uber Elevate missions using its Slowed Rotor/Compound technology.

2017 Carter Air Taxi
The version announced at the 2017 Uber Elevate Summit is capable of powered hover and swivels the tailrotor to provide anti-torque. The battery is in the nose. The Carter air taxi is expected to cruise efficiently at ~175 mph.It has a 34 ft diameter rotor and wing span, a 10 ft diameter pivotal tail rotor/thruster is used to counter rotor torque during hover, and then as the aircraft accelerates and the rotor converts from helicopter to autogyro mode, it pivots to provide 100% thrust. There’s no torque going to the rotor above about 100 mph. The cabin width is 54” wide for a very roomy & comfortable luxury passenger feel. The aircraft is designed for an empty weight with batteries of 3,200 lb, to be able to carry an 800 lb useful payload (e.g. four 200 lb people), for a gross weight of 4,000 lbs. (Note: At the Uber Elevate Summit, Carter announced that they were partnering with Mooney International; however, this partnership was later abandoned.)

At the Uber Elevate Summit in 2018 and at the Vertical Flight Society’s 74th Annual Forum in May 2018, Carter unveiled a new configuration that removed the swiveling tail and instead had four electric motor-driven propellers on a longer wing. The Carter Electric Air Taxi is designed to sit up to 6 people, with a slower rotor that enables high speed forward flight, low drag, low tip speed/noise and no retreating blade stall. The high inertia low disk loaded rotor acts as a built-in parachute, but works at any altitude/speed and provides directional control. The tilting mast controls the aircraft pitch at low speeds and rotor rpm for high cruise efficiency at high cruise speeds.
