There are many who are using this engine successfully Zonuna. There are whole list of video of guys in Youtube who have flown with this engine.

Guess the connection with NGH and this product. I am absolutely thrilled. ordered four more of these.

O.S. Glow Gas Plug G5 for GGT15

http://www.rcdhamaka.com/index.php?main_page=product_info&products_id=1784


For that mater this is a good product for any glow engine which you want to run on gas. More review and test result to follow.

i wonder how this works - i thought that all petrol engines required a spark plug and associated
ignition/timing circuitry.

if this could be applicable to bikes a it would simplify things a great deal,

efficiency  must be taking a hit.

There is a brand new OS glow gas engine which is on sale which uses this plug in place of spark plug and CDI ignition.  Which is also using crank pulse pressure for fuel feed.

Exactly as expected when I replaced the sparkplug of NGH with this plug. It was happily firing away without missing a beat even after removing the 1.5volts supply. Will not comment further before full test with this plug.

will that GG plug work on O.S MAX-46AX engine ? (newbie in glow) and assuming it works all one needs is gas with oil ?

The glow gas engine has a fuel pump operating from pulse pressure of crank in addition unlike a normal OS glow engine.

Compression of a Glow Engine's ABC Sleeve and ring-less piston per say is much higher compared to a 2 stroke Gas engine with a ringed piston. Further the viscosity of gas fuel is very less compared to a glow fuel and it needs a fuel pump to regulate the fuel feed and it cannot rely on a exhaust pressure feed entirely like a glow.

I am expecting along with a perry pump operating with the pulse pressure from the crank it can be used with a well bedded glow engine. You need to add a nipple to the crank back plate to tap the pulse pressure to feed the perry pump.

I cannot really comment on how it will perform on a glow engine with tapered sleeve at TDC like APC. May be one can try on a old engine which has already worn out.

Thanks for the explanation sundaram.

Thats is great Sir, I have a new ngh gt9 that have not used mainly due to its negetive reviews.  I will convert this to glowplug now. Does the glow plug fit directly or any additional fitting required.


It is out of stock now in Rcdhamaka. Will wait until stocks come back,

Thanks

The glow plug fits straight in the plug thread since its same threads as a regular glow.

Most have issues with engine due to the faulty setup of fuel pump and poor quality CDI ignition which came in the initial lots.

High speed full RPM setup should be done once engine becomes warm or else once engine warms up it behaves lean in the same setting done cold. You may have to open half turn or more H'S needle to prevent ignition cutout in WOT.

After using this engine with both CDI Ignition as well as Glow gas engine for quite some time now I have come to conclusion that main issue with this Engine is its Fuel pump. Wonder when NGH is really contemplating on introducing a new Fuel Pump design.

Other than that this engine is pretty much usable. Damn it has an excellent fuel efficiency, runs forever on a 300 ml tank. You just have to get the hang on how to tune the fuel pump or use alternate method to feed fuel. It needs emphasis here that alternate methods to get optimum feed of fuel is equally difficult to tune if not more in comparison to tuning the existing fuel pump.

For all the   fans and for me this engine has still proved to be unreliable for Prop hang.

Upgraded NGH GT09 has been launched. This one has both Carburetor and fuel pump clubbed into one unit of Carburetor like any other Gas engine.

Cost of the entire engine unit with the carb cost same as old engine. But however if you want to buy just the carb it costs half the engine cost.

how is this just 40$ only (Click for aliexpress link)

Gusty there was one available for 27$ too earlier now not seen. This is definitely the latest pump with both inlet and out let in same direction.

But the one posted by me has the pump stage on the carb itself. So no need for a separate pump mounted on a bracket.

That's cool buying one
