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

EWZ-S
EWZ-S is a micro air vehicle (MAV) developed by Ewatt, and it is a quadrotor. Landing gear system consists of a pair of skids, and this unmanned helicopter is the larger cousin of the larger EWZ-S8. EWZ-S is constructed of aluminum alloy and carbon fiber. Specification:
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. Specification:
EWZ-I
EWZ-I UAV is an unmanned helicopter developed by Ewatt in conventional helicopter layout and the landing gear system consists of a pair of skids, and this UAV is powered by a twin cylinder gasoline engine, and constructed of aluminum alloy and carbon fiber. Specification:
EWZ-II
EWZ-II is an unmanned helicopter developed by Ewatt in conventional helicopter layout and the landing gear system consists of a pair of skids and this UAV is powered by a gasoline engine, and constructed of aluminum alloy and carbon fiber. EWZ is the larger cousin of the smaller EWZ-II, and like its smaller cousin, it is also constructed of aluminum alloy and carbon fiber. Specification: .
EWZ-120
EWZ-120 UAV is an unmanned helicopter developed by Ewatt in conventional helicopter layout and the landing gear system consists of a pair of skids and this UAV is powered by a gasoline engine, and constructed of composite material. Specification:
EWG-1
EWG-I UAV is a fixed-wing UAV of conventional layout with high-wing configuration. Propulsion is provided by a two-blade propeller driven by a tractor engine mounted in the nose. EWG-1 is gasoline-powered and is constructed of aluminum alloy and carbon fiber.
