It is appropriately called “Megacopter” and this drone has set the Guinness World Record by lifting in the air a load of 61 kilograms or, approximately, 134 pounds.
The Voltron-like mashup consists of eight smaller drones held together with a wood and aluminium frame. It uses the power of 13 rotors and four dozen individual motors to achieve the feat. It has been designed and built by students at the University of Oslo. The wait was supported by four inflatable exercise balls to make the landing smooth after the heavy lift.
To be frank it is not a single drone. As the name says, it is a multi-copter, a collection of drones working in unison. But the point is, 61 kilograms were lifted into the air by the single megacopter made with multiple copters, but controlled with a single remote. In order to make the record, the drone had to keep the weight off the ground for at least 30 seconds. Here is a video of the megacopter lifting 61 kilograms and making the Guinness World Record.
Actually the record was set in October 2015 but it takes some time for the Guineas World Records to validate the claims and officially include them.
You need to keep in mind that the actual weight that was in the air was more than 76 KG because along with the weight of the individual drones, there was also the weight of the batteries.
