The Ancient Greek

In the western world, the ancient Greek mathematician, physicist, and inventor, Archimedes, who lived and worked in the second century B.C.E. perfected the principle of the rotating screw for use as a water pump. When the screw was rotated inside a cylinder, the screw moved the water in front of it. At the same time, the water resisted and pushed back. This resistance also applied to the movement of screws through aira type of fluid.
The 15th century Italian Leonardo da Vinci has often been cited as the first person who conceived of a rc helicopters capable of lifting a person and then experimented with models of his designs. His sketch of the “aerial-screw” or “air gyroscope” showed a device with a helical rotor. The helical surface on his device resembled a electric rc helicopters and was made from iron wire and covered with linen surfaces made “airtight with starch.”
