The Drone Racing League (DRL) has managed to build the fastest drone in the world: the DRL RacerX, which is actually capable of reaching a top speed of 179.6 MPH, has claimed the Guinness World Record... Racing Drone Sets Guinness Speed Record at 163 MPH
How the hell such a small drone can grab so much air with those tiny propellers to be able to achive these insane speeds!? On what rpm motors are working on those, 30K, 50K, more?
I am into RC and electronics. But I prefer slow as hell bi-plane. It is more enjoyable to control. And can stay in air much longer with same battery.
