Page "Roadable aircraft" Paragraph 41

* Urban Aeronautics ' X-Hawk is a VTOL aircraft which operates much like a tandem rotor helicopter, however it doesn't have the exposed rotors which make helicopters dangerous for personal use.

This is accomplished by containing the rotors in large ' ducts ' which make up most of the body of the craft ; the requisite decrease in rotor size also decreases fuel efficiency.

The X-Hawk is being promoted for rescue and utility functions.

It is scheduled to be available for about $ 3 million around 2010.
