The selection of drone material and the motor is as such to meet the requirement of high speed and to overcome crashes which are quite inevitable during the race. There are many organizations which organize these kinds of events such as DRL (Drone Racing League), U.S. National Drone Racing Championship and many others.
These organizations provide their own drone materials in order to level the playing field and verify the skills of pilots across a large number of participants. Drone racing provides excitement not only through pure speed and agility, but also though the robustness in the design of these drones.
