Ewatt UAV
Ewatt UAVs are Chinese UAVs developed by Hubei Ewatt Aerospace of Ewatt (China) Co., Ltd. (Ewatt, 湖北易瓦特科技有限公司) whose engineering group has been leading the design of so many types of successful UAV models. Ewatt UAV made their public appearance in 2013 in Washington DC Association for Unmanned Vehicle Systems International[1][2]

EWZ-S8
EWZ-S8 is another MAV developed by Ewatt, and it is an octocopter. Landing gear system consists of a pair of skids. This unmanned multirotor differs from most of the rest of unmanned Chinese multirotors in that instead of having arms attached to the center like in EWZ-S, EWZ-S8 has a rectangular frame with short arms protruding from each of the four corners. A pair of rotors are attached to the top of each arm, one above the arm, and the other below. EWZ-S8 is constructed of aluminum alloy and carbon fiber.[5] Specification:[6]
