The 800 gram drone hit a speed of 179.6MPH, but because the official record is the average top speed of both legs of a back and forth flight, the Guinness entry is 163.5MPH. "The record-setting RacerX represents the culmination of years of technological innovation by our team of world class engineers, and we're very excited to unveil the fastest racing drone on earth," said DRL CEO Nicholas Horbaczewski in a statement. DRL said that earlier versions of the RacerX burst into flames when reaching top acceleration speeds because of how much power was used.
