ZWYX YX
YX series UAVs are Chinese UAVs developed by Beijing Zhong-Wei-Yu-Xiang Aerial Co., Ltd. (ZWYX, 北京中纬宇翔航拍技术有限公司), and have since deployed by various Chinese governmental establishments. YX-1. YX-1 is the first UAV developed by ZWYX and it has a conventional layout with propulsion provided by a two-blade propeller driven by an engine mounted in the nose. Specification: YX-2. YX-2 is slightly larger than YX-1 and also adopts conventional layout like YX-1. YX-2 has three vertical stabilizers in a configuration with two smaller ones on either side of the larger one in the center. YX-3. YX-3 appears  to be a scaled-down version of Iflyer Hunter UAV, and both Chinese UAVs have identical twin-boom layout with twin-engine propulsion, and both have tricycle landing gear. The airframes of these UAV are only slightly different. What differentiates the two is in their flight control systems which are independently developed by their respective developers.
