AN AEROBATIC UNMANNED AIRPLANE CAPABLE OF NOSE-DOWN HOVERING MANEUVERS 5 An aerobatic UAV capable of precise yet powerful roll control while in nose-down hovering flight comprises at least two dedicated wingtip rotor units (4a), (4b) for the roll control while the main rotor unit (3) provides thrust that can be directed forwards or backwards as well as cyclic controls that actuate the pitch and yaw of the said aircraft without the use of conventional flight control surfaces. Its 10 unique aerial maneuverability leads to the creation of a new 4D aerobatic maneuver known as "typhoon" which not only appeals to radio controlled model aircraft enthusiasts but also an innovative platform to substitute the expendable dropsondes for in-situ severe weather reconnaissance. 15 Most Illustrative Diagram: FIG. 3 6no -4 m & mN
