Engine + Generator Integrated Hybrid System for Long-Endurance UAVs

The 70cc hybrid engine is a hybrid power platform designed specifically for UAVs, combining the advantages of a gasoline engine with the efficiency of a high-performance generator. It provides propulsion power for the aircraft while simultaneously supplying stable electrical power to various avionics systems during flight, making it the optimal solution for long-range mission operations. This next-generation power solution supports extended endurance, high power output, and stable operation even when multiple mission payloads are in use.
