The team behind TF-X, patented in 2011, will see the two-foot-long unmanned aircraft headed to the skies. The scale model is permitted to reach a maximum height of 121 meters, and a maximum speed of 100mph. While it is allowed to use U.S. air space, the team must be in constant communication with FAA authorities. The data collected during the special FAA-approved test runs will help Terrafugia plan the future development of design for its flying cars. The testing will also allow the engineers to assess the hovering capabilities of the drone.
