It is well-known that helicopters, and other UAVs, with heavy-load carrying capacities exist. But there are multiple problems associated with making an electric drone which can carry more than its weight.
One of the problems is that helicopters use fossil fuel for power generation. The fossil fuels have a greater energy density than electric batteries. Therefore, Sörensen first had to figure out the perfect power needs for his ambitious drone project.
The battery is just one component of a drone, the frame, motor, rotors, and other equipment used in it too can weigh a drone down. Therefore, the creator settled on using a lightweight alternative – i.e. aluminum – for its arms.
For the central part he went for a wooden base, which connects the four arms of the drone with 11.5 feet (3.5 meter) diameter.
