Eleron 3 SV drawing:
-Several variations exist, concerning stabilizers, types of the main Pan–tilt–zoom camera and the static down looking camera. 
-The digital military camouflage pattern, covering the topside of the drone in most military applications, is missing in this drawing for better clarity of the written Cyrillic instructions on the drone.
