The Briton collected a giant multicopter with 54 screws and took off on it
The British inventor collected Superrone with 54 screws connected together. The device is called The Swarm-“Roy”-due to the sound that it makes in flight.
The multicopter can lift to 148 kilograms and be in the air for 10 minutes. There is a place for a pilot in Roy, and, as can be seen on the video, the tester dared to take off a few meters up.
