1. A ducted fan air-vehicle comprising: an air duct comprising a fan;a center body connected to the air duct;a plurality of pairs of control vanes located downstream from the fan, wherein each pair of control vanes of the plurality of pairs includes a first control vane and a second control vane, th
1. A ducted fan air-vehicle comprising: an air duct comprising a fan;a center body connected to the air duct;a plurality of pairs of control vanes located downstream from the fan, wherein each pair of control vanes of the plurality of pairs includes a first control vane and a second control vane, the first and second control vanes being adjacent to each other;a separate servo for each control vane; anda flight control system configured to independently control movement of each control vane via the respective servo of the control vane, wherein, for each pair of control vanes of the plurality of pairs, the flight control system is configured to deflect the first first and second control vanes towards each other. 2. The ducted fan air-vehicle of claim 1, wherein each control vane includes a moveable flap surface configured to deflect as the flight control system deflects the control vane. 3. The ducted fan air-vehicle of claim 1, wherein each servo is mounted onto a respective control vane of the plurality of pairs of control vanes. 4. The ducted fan air-vehicle of claim 1, wherein each servo is located outside of a respective control vane of the plurality of pairs of control vanes. 5. The ducted fan air-vehicle of claim 1, wherein the center body includes at least one of an engine, a camera, or an avionics system. 6. The ducted fan air-vehicle of claim 1, wherein the flight control system is configured to independently control two adjacent control vanes to deflect the leading edges of the two adjacent control vanes towards each other to generate a drag force on the air duct. 7. The ducted fan air-vehicle of claim 1, wherein the flight control system is configured to independently move control vanes of the plurality of pairs of control vanes to control pitch, roll, and yaw moments of the ducted fan air-vehicle. 8. The ducted fan air-vehicle of claim 1, wherein the flight control system is configured to move adjacent control vanes of the plurality of pairs of control vanes independently of each other. 9. The ducted fan air-vehicle of claim 1, wherein the flight control system is configured to independently two control vanes of each pair of control vanes of the plurality of pairs of control vanes to deflect leading edges of the first and second control vanes in a same direction and to deflect the leading edges of the first and second control vanes towards each other. 10. The ducted fan air-vehicle of claim 1, wherein the fan comprises a plurality of blades, and wherein the flight control system is configured to activate the servos of each control vane of the plurality of pairs of control vanes to simultaneously deflect the plurality of pairs of vanes to change a thrust of the air vehicle without changing a speed of the fan or changing a pitch angle of the blades of the fan. 11. The ducted fan air-vehicle of claim 1, wherein the flight control system is configured to activate the respective servos of the first and second control vanes of only one pair of control vanes of the plurality of pairs to deflect the first and second control vanes towards each other and tilt the ducted fan air vehicle. 12. A method for controlling a ducted fan air-vehicle, the method comprising: with a flight control system of the ducted fan air-vehicle, independently controlling movement of at least two adjacent control vanes of a plurality of control vanes of the ducted fan air-vehicle, the ducted fan air-vehicle comprising:an air duct comprising a fan;the plurality of control vanes downstream of the fan, the plurality of control vanes comprising a plurality of pairs of control vanes, wherein each pair of control vanes of the plurality of pairs includes a first control vane and a second control vane, the first and second control vanes being adjacent to each other; anda separate servo for each control vane of the plurality of control vanes, wherein independently controlling movement of the at least two adjacent control vanes comprises, for each pair of control vanes, with the flight control system, independently actuating the respective servos of the at least two adjacent first and second control vanes to deflect the first and second control vanes towards each other. 13. The method of claim 12, wherein the plurality of control vanes comprises four pairs of adjacent control vanes and wherein independently controlling movement of the at least two adjacent control vanes comprises, with the flight control system, controlling the servos of each of the control vanes to deflect leading edges the control vanes of each pair toward each other. 14. The method of claim 12, wherein each servo is mounted onto or internal to a respective control vane of the plurality of control vanes. 15. The method of claim 12, wherein each servo is located outside of a respective control vane of the plurality of control vanes. 16. The method of claim 12, wherein independently controlling movement of the at least two adjacent control vanes comprises independently controlling at least one pair of control vanes of the plurality of control vanes to deflect leading edges of the first and second control vanes towards each other and generate a drag force on the air duct. 17. The method of claim 16, further comprising independently controlling the first and second control vanes of the at least one pair of control vanes to deflect leading edges of the first and second control vanes in a same direction. 18. The method of claim 12, wherein the fan comprises plurality of fan blades, and the method further comprises, with the flight control system, independently controlling movement of the plurality of control vanes to generate a change in a thrust of the ducted fan air-vehicle without changing a speed of the fan or pitch angle of the fan blades of the fan. 19. The method of claim 12, wherein the fan comprises blades, the method further comprising: with the flight control system, activating the servos of each control vane of the plurality of control vanes to simultaneously deflect the plurality of control vanes to change a thrust of the air vehicle without changing a speed of the fan or changing a pitch angle of the blades of the fan. 20. The method of claim 12, further comprising, with the flight control system, activating the respective servos of the first and second control vanes of only one pair of control vanes of the plurality of pairs to deflect the first and second control vanes towards each other and tilt the ducted fan air vehicle.
