In addition to the latest functionalities (altitude hold & headless mode), the JJRC H68 Bellwether drone features up to 20 minutes flying time (depending on how you fly).  The 720P camera is attached under the belly of the drone using some vibration damping balls. In order to obtain the best field of view, the angle of the camera can be adjusted from straight ahead to ground view (45 degree).

Earlier helicopters used tail rotors to counterbalance the torque generated by a single, main rotor but this was inefficient, complex and wasteful. To solve the problems that helicopter pilots had with performing vertical flights,engineers developed quadcopters. These quadcopters were among the first VTOLs (Vertical take-off and landing) aircraft.  Aircraft evolved rapidly during The First World War, with unmanned concepts soon following, culminating with the Kettering Bug, a biplane which flew on a pre-set course using an on-board gyroscope and altimeter. A similar idea, underpinned perhaps the most infamous of Second World War drones, the V-1 Flying Bomb or Doodlebug, which devastated London...
