Director Drone Racing League Ryan Guri, along with a team of engineers have created a quadcopter capable of accelerating up to 289 km/h. He was already in the Guinness book of records as the fastest racing drone on the ground. This is not surprising, as the previous maximum recorded speed was 128 km/h.

Unmanned DRL RacerX weighs just 800 grams and can accelerate much faster than cars. The speed of rotation of the rotor it reaches 46000 rpm as the battery is used the combination of two Li-Po batteries 5S with a capacity of 1300 mAh.

During test flights the maximum measured speed on the straight made up of 289 km/h. But as for fixing achievements as Guinness world records required that the drone flew back and forth through the interval of 100 meters, the maximum speed was 263,1 km/h. In any case, this result significantly higher than previous models.
