The helicopter craft design is chosen owing to its ability to take off and land vertically, eliminating the need for large runways, as well as the stability of the craft during flight and hovering, with it being sensitivity to precise turns and easy to direct in a small area
The craft itself is powered by a 2600mAh battery which is then charged by the lightweight solar panel array, greatly extending the flight time.
The craft can also be charged on sight when landed, greatly increasing the potential for automation and reducing dependence on centralized energy infrastructure.
The solar panel array is made of Amorphous thin-film silicon (ATF-Si) solar cells, each having an energy gathering efficiency of up to 20%. These solar cells are light enough to cause no significant weight added to the craft.
