Do you want a quadcopter that is capable of flying for three hours? Well that amazing feat isn’t going to happen using traditional batteries. Regardless of their density, todays battery packs can’t match the power density of good old gasoline. Gasoline powered quadcopters are a different animal altogether, requiring different flight control system than the consumer drones we are all familiar with. The SOAPdrones team figured it out and have a working quad that can carry 22 lbs and fly for three hours.
What does it take for a quadcopter to carry a 10-kg (22-lb) payload and fly for three hours straight? It takes petrol power – and a clever variable pitch rotor system that makes this gas-powered drone just as stable, quick and responsive as its electric brethren. Scaled up, it could carry 200 kg (441 lb), which is more than enough lifting power for a manned multirotor.
