==CK-GY04 CHY==
CK-GY-04 CHY is a development of CK-GY-04 Survey Eagle with slightly smaller size, but the UAV is constructed more advanced composite material instead of fiberglass used earlier in CK-GY-04 Survey Eagle. The utilization of advanced [[honeycomb structure|honeycomb]] composite material reduces weight and extends the endurance by more than double the original endurance of CK-GY04 Survey Eagle, and achieved the same normal operating radius with eighty percent of the fuel originally needed.
