A father-and-son duo, Luke Bell and his father Mike, of Western Cape, South Africa, created the world`s fastest drone, with an average top speed of 298.47 mph.

Dubbed Peregreen 2, the quadcopter is 3D-printed carbon fibre, battery-operated and remote-controlled. The duo tapped aerothermal engineer Chris Rosser for help controlling it. To nab the record, they flew the drone in two runs in opposite directions, demonstrating its ability to navigate tail or headwinds. They clocked an actual top speed of 317 mph and an average of 298.47 mph.

The Bells created the device over months, troubleshooting problems, including electrical fires caused by overheating wires and batteries.
