Indepedently to Uriah's advice on tuning your engine, this is what you need to know about chosssing the correct glow plug....

Turbo Glow Plugs where designed to give more performance to an engine, for the following reasons:

•It forms an uninterrupted combustion chamber.
•The advantage of better heat transfer or heat dissipation, and a leak proof seal, generated by the conical seat of the plug.
•Greater choice of thermal ranges, that allow for a more precise tuning according to variations in weather conditions (temperature, humidity, altitude, barometric pressure, etc.).

The numbers and characters on the plugs, are the product number, wire thickness, and thermal range of the plug’s body. Example:
The Novarossi C7TG (F) or (C)
Product: C (Conical)
Wire Thickness: 7
Plug Type: T (Turbo)
Plated:G (Gold)
Thermal Range: F (Fredda = Cold) C (Calda = Hot)

The plugs with cold thermal range F (Fredda), have a body with thinner walls and shorter body, so they dissipate heat better and faster to the engine head. The plugs with hot thermal range C (Calda), have a body with thicker walls and longer body, so they retain heat and dissipate heat slower to the engine head. The number of threads is the same on both types of plugs.

How to select the proper plug:
•When the ambient temperature is high, we have to use a plug with thicker wire.
•With higher compression, we have to use a plug with thicker wire.
•Humidity determines if we use a Cold (F) thermal range, or Hot (C) thermal range.
•With high humidity percentage we should use a Hot (C) thermal range plug.
•If we have high temperature and high humidity, we should use a plug with thick wire and a Hot(C) thermal range.

So with up to 20% Nitro you are OK with #5 or 6 plugs, but from 25 to 30% nitro is best you go with #7 or even #8.

Now since you have such a high temp high humidity environment, you should go with C (hot) thermal range type of plug. C7TGC or C8TGC plugs.

Hope this helps

In my opinion, for 25 - 30% Nitro, and such high humidity, you should add a 0.10 shim.....lets see what Uriah says about it.

Yes, you need to add at least .1mm to run 30% nitro. Use the stock .3mm for up to 20%. 20%-25% you can use .4mm total shims, and for 30% you can use .4-.5mm of shims, especially if it is hot, and humid.

Really? The C7TGF were always (and are still) black with a gold tip. The C7TF (without the "G") had a silver body and mine had also silver tips. However, I had a lot of issues with C7TGF (black with gold tip). Never sucked a wire through the engine, but some were not glowing bright enough (impossible to tune engine) or died after the run (could not start for the next run).
I was thinking that this could also come from using a heat gun to warm up the engine (pointing at the plug), but my buddys use it as well and don´t have issues with the plugs...

What is a good 1/8th scale pipe to run with the Cordoba or a R9?

Hi Jeremy. Sorry for the delay. The engine will be shipping today. I was waiting on the 2652 pipes that I was told would arrive from the importer. They did not. I will have to mail the pipe to you in a couple of more weeks. The US supply of some on road Novarossi engines, and pipes is terrible. I have been waiting over 6 weeks for them. I will probably wait another couple.

Again I am sorry for the delay on the pipes. I waited to ship everything because I was told by the importer the stuff was coming in, that did not happen. Let me know if this is OK.

What is the R9? Do you mean the JP R09? For the Cordoba engine I like the Novarossi 2015 pipe best. It gives the best combination of runtime, and power. It is also very linear. The 2052 is also good. It is a little more peaky feeling. The JP engine likes the same pipe.

I will post a picture of the silver plugs with gold tip. They are C7TGF I have a bunch of them I will never use. I think I may send them back to Nova. I do not want to sell them to my customers knowing they are bad.
