This electrically driven system is quiet, clean and economically cost efficient. A one-hour flight would cost something near to 6 Euro for electricity. In addition, the device holds few parts, which could wear out, making maintenance intervals and cost low and far between.
The control firmware can be integrated with a sophisticated integrated GPS system or obstacle detection. As such, automated flight for predetermined points on a 3D map is possible. In addition to the relieving the pilot of strenuous navigational tasks, unmanned flight would be feasible similar to other devices (drones)."
