Product details

GT9 Pro 9cc Two-Stroke Engine from NGH - NGH-GT9PRO

Here at Stirlingkit we are pleased to present our customers with the NGH line of gas engines. NGH have become known for building quality gas engines that offer light weight, power and reliability at a very affordable price. They are manufactured and designed from scratch for model aircraft, they are not modified chainsaw or similar types of engines that have been in the past, they are purpose made.

The GT9 Pro is the second generation of this popular engine, it has been re-designed to give even more power and has a completely new NGH 20G Pro twin needle carb to give good reliable running and throttle response plus easy starting. The internal diaphragm pump of the cylinder is driven by the cylinder from the side of the cylinder to give fuel to the flow whatever the attitude of the aircraft and regardless of the tank position. The ignition system is the new NGH automatic advancing angle system that is manufactured for them by Rcexl who have been manufacturing ignition systems for many years.

An all new one piece carb has flawlessly overcome the problems normally associated with very small gas engines. The conrod is now machined from solid phosphor bronze like the GT17. It is the same physical size as a 40 - 50 sized glow engine so will drop straight in to your model with minimum fuss. The mounting for the exhausts are the same as 40 - 50 glow sized engines as well, so a range of exhaust options are possible.

The 9cc shares many other features with its bigger brothers including the RCEXL ignition. Choose the GT9 Pro for your next project and you won't be disappointed.
