NGH have been known for producing high-quality gasoline engines.NGH is also the first factory in China that independently develops and produces 4-stroke RC gasoline engines.GF38 is a professional-grade 4-stroke gasoline engine built by NGH engineers for model enthusiasts, high performance, low fuel consumption, large torque, low noise, compact structure and beautiful appearance.
GF38 has the installation size of 160-240 glow size 4 stroke engine, and it has power comparable to a 160-240. It is suitable for RC aircraft with takeoff weights of 8-12kg and is the best power configuration for the 160-240 level RC aircraft.
GF38 uses a CM6 spark plug and has standard NGH directional exhaust pipe to make the low voice and high power. The CNC carved and anodized adjustable-length T-type engine mount is equipped to make the engine installation more stable and less vibration.
The rear carburetor facilitates engine adjustment, connecting rod with needle bearing can lubricate the hinge pin better, and unique double piston ring (one lubricating ring and one sealing ring) can seal and lubricate better. The cylinder liner is made of wear-resistant nodular cast iron, the tolerance of the bore in the cylinder is within 0.01mm, and the precision is much higher than the roundness tolerance of the inner hole of the aluminum alloy chrome-plated cylinder liner 0.03mm, aluminum alloy plating chromium cylinder liner in principle does not meet the Eu environmental regulations.
GF38 features:
* NGH directional exhaust muffler for low voice
* The matched Walbro carburetor for reliable running and convenient installation
* CNC carved and adjustable T-shaped engine mount for more stable engine installation and less vibration
* CNC carved double needle roller bearing connecting rod
* Double nut locking output shaft
* RCEXL Ignition with automatic advancing system, especially made for NGH
* RCEXL spark plug CM6
* High-quality bearings
