Simon Sörensen, creator of the RCLifeOn YouTube channel, has shared in a nearly 18-minute long video the creation of a heavy-duty drone capable of lifting up to 100 kg of payload . This project challenged the limits of home-made engineering, facing obstacles related to the weight of the device, the necessary battery, and technical programming issues.
A meticulously built “homemade drone”
To design this heavy-lift UAV , Sörensen began by determining the critical energy requirements for the drone to carry more weight than its own frame. The lithium polymer battery, while lightweight, was a major limitation, as it did not provide the same energy density as conventional fuels used in helicopters .
Despite this challenge, the designer opted for lightweight materials such as aluminum and carbon fiber , which allowed the overall weight of the device to be reduced without compromising its load-bearing capacity.
The drone was built with a wooden base that connects four aluminum supports and carbon fiber propellers that, in addition to reducing weight, increase strength and durability. The total weight of the drone is just 20 Kg , making it an outstanding example of lightweight engineering.
Flight problems and creative solutions
Despite innovative construction solutions, the first flights of the heavy-lift drone were not without problems. After several failed attempts and adjustments, Sörensen managed to get the drone off the ground.
During the initial flight, the aircraft experienced some drift and failed to land on the first attempt. However, with some further adjustments and precise calibration of the control system, the drone proved that, with the right battery, it can effectively lift up to 100 kg of payload .
The creator has made it clear that the drone is not only a technical achievement, but also a testament to what home-made technology can achieve. Although the version presented in the video can lift up to 100 kg, the theoretical maximum capacity of the device is 160 kg. This opens up new possibilities for the future of cargo drones, especially in sectors such as logistics and freight transport .
