While early SureFly models will be pilot operated, the company hopes future versions will operate autonomously. The SureFly will carry two people as far as 70 nm to altitudes of 4,000 feet. The aircraft uses a gasoline-fired piston engine to drive the dual generators needed to power its eight electric motors, each driving a single propeller. The machine incorporates a dual Lithium battery pack as an engine-failure back-up and comes standard with a ballistic parachute system. Retail price of the potential air-taxi machine is just $200,000.
