In case you haven’t seen it yet, this video has been taking the internet by storm. The YouTube user [Gasturbine101] has successfully taken flight in his home made multi-rotor flying machine.
It’s a massive array of high powered brushless motors with props, fifty-four in fact, all counter-rotating. It has a weight of 148kg (we assume this includes the inventor), and produces a maximum lift of 164kg. Apparently it’ll even last for about 10 minutes. The props are grouped into six, using Hobbyking stabilizers to balance the flight.
He calls it the Swarm.
