Mountain Eagle (Shan-Di-Ying or Shandiying, 山地鹰) series UAVs are Chinese UAVs developed by Chengdu Institute of Mountain Hazards and Environment (IMHE, 中国科学院•水利部成都山地灾害与环境研究所) of CAS and Ministry of Water Resources of the People's Republic of China (MWR). The existence of Mountain Eagle was first publicized in 2013 when they were deployed for post disaster accessement mission in 2013 Lushan earthquake. Two models of Mountain Eagle series UAVs have been identified, the smaller one is in conventional layout with high wing configuration, and it is approximately one meter long. This smaller model and has a ceiling of 1 km and is usually recovered via recovery net. The larger model is approximately one and half a meter long and has an ceiling of 6–7 km.[11]
