NGH is famous for producing high-quality gasoline engines, and is also the first factory in China to independently develop and produce small multi-cylinder four-stroke gasoline engines. GF150R5 is a professional four-stroke gasoline engine built by NGH engineers for RC aircraft and fixed-wing UAVs, with high performance and low fuel consumption, large torque and low noise, compact structure and beautiful appearance.

GF150R5 uses CM6 spark plug, standard equipped with NGH special annular exhaust device, smooth exhaust, low voice, surging power and less vibration.

The rear matched WALBRO carburetor makes engine adjustment simple and convenient; The connecting rod is equipped with needle bearing to better lubricate the pin shaft; Unique separate lubrication circulation system makes engine lubrication more sufficient; Unique double piston rings (one lubricating oil ring and one sealing ring) can better seal and lubricate; The unique supercharging structure increases the adaptability of the engine to the environment; The cylinder liner is made of wear-resistant ductile iron. The roundness tolerance of the inner hole of the cylinder block is within 0.01mm, and the accuracy is much higher than 0.03mm of the inner hole roundness tolerance of the aluminum alloy chrome-plated cylinder liner. In principle, the aluminum alloy chrome-plated cylinder liner does not meet the environmental protection requirements of the European Union.
