Product Q&A

NGH started to use the new carburetor of GT17-pro 2-stroke gas engine in March, 2022. And GT17 was upgraded into GT17-Pro. The new carburetor matches the engine better, with a more refined appearance and easier installation. The engine performance has been further released. The idle speed and stability have been significantly improved. The idle speed has been increased from the original 2000rpm into 1700rpm (using a 16*8 propeller). The high and low speed transitions are smoother, and the linear performance of the engine is fully reflected.

GT17-Pro 17cc engine is a professional two-stroke gasoline engine built by NGH engineers for RC enthusiasts, compact structure, beautiful appearance, stable performance and plenty of power.


GT17-Pro has the installation size of 61-91 glow size 2 stroke engine, and it has power comparable to a 91. This makes it the obvious choice for a kit that requires a 61-91.


The front carburetor can increase the air intake of the carburetor by the pressure of the propeller to achieve the purpose of increasing the engine power. When installing the RC aircraft, the front carburetor will not be interfered by the firewalls. Using the integral bronze connecting rod, when completely running in of the engine, the bronze connecting rod will be more durable, and the wear resistance and durability are far exceed to high-quality needle roller connecting rod. 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. The engine intake system adopts the crankshaft intake mode, which is more accurate than the reed valve intake mode in opening and closing time. Because the spring delay of the reed itself is different from the negative pressure of the crankcase, the intake time is not accurate. Optional surround exhaust pipe can effectively improve and reduce noise, and it is deeply high praised by European and American RC enthusiasts.
