Found out they've actually got some really neat looking rendering technologies. This example being a cartoonized, cell-shaded equivalent of LIDAR point cloud scan.

4.7" x 4.7" seems reasonable for some drones. Based on https://en.wikipedia.org/wiki/Unmanned_aerial_vehicle the smallest class of drone is: < 20 lb (9.1 kg)
It would also fit into the Micro air vehicles (MAV) and larger categories. Micro starts at: >= 250 gm & < 2 Kg. Large is considered 150 kg.
