YTHS HS
YTHS UAVs are Chinese UAVs developed by Beijing Asian Pacific Hong-Sheng Aviation Science and Technology Co., Ltd. (YTHS, 北京亚太宏升航空科技有限公司) (APHS), which was originally formed as an importer and Chinese distributor of western commercial off-the-shelf (COTS) airframes, flight control systems such as autopilots. YTHS has since expanded its business by developing its own flight control systems and become a system integrator of COTS systems by integrating flight control systems it developed and markets with COTS airframes.
HS-12D
    
HS-12D is an unmanned helicopter developed by APHS in conventional helicopter layout, and the landing gear system consists of a pair of skids. Electrical power produces less noise and enables the unmanned helicopter to fly at higher altitude.[1]
