Aerodynamic racing drones are designed to move forward

Most prefabricated drones that are available in shops are quadcopters, and are steered by adjusting the motor power of four individual rotors. Ordinary hobby drones are typically symmetrical with the four rotors located in an X from the body. Consequently, the drones are balanced and can be manoeuvred equally well in all directions. The DRL racing drones, on the contrary, are shaped as a narrow H to reduce air drag. They only need to fly in one direction: forward.
