Car folks tend to use more nitro, so the medium plug #8 would be a better choice.  A3 *may* work better if you use no nitro, the extra heat is better suited for that scenario.

If you are using more than 10%nitro then go for OS no8 else use A3

The idea is to run engines at "optimal" temperature, not "hot".

I will recomend you to buy one of both type and then use them the one you feel is better is your choice

Using A3, your engine will heat up alot and this is not good if you want your engine to last.. A3 makes it easy for you to start the car but it is not recommended...

Hey! The glow plug, by itself, does not make the engine run hotter or cooler. "Hot" plugs are used with low/zero nitro mixtures and 4 stroke engines, "cold" for high nitro mixes. The reference is to the PLUG temperature and NOT the engine!

its really cold in north and the stock plug (R2+) from TTr has failed

OS #8 is one of the most versatile plugs in this business.  And "versatile" is meant to convey that it is used in a variety of situations.

The OS #8 is a fine general purpose plug. Seems to work pretty well on most engines.

What do mean by "failed"? Is the filament blown?

Have you ever tried running your car for 15 mins flat out ?.. Do you have temp gun to see what is your constant temp?. With 15% nitro on a hot plug (OS A3) the temp was 280 to 320.. With the same setting i ran a Medium plug (OS A8), the temp was 240 to 260.. With same setting on a cold plug (Enya 6) the temp was between 180 to 220.. Please let me know if you had you own experience.. If you are answering these questions based on research, pls note that most the guys who share the exp come from a not so hot country like ours.. Engine temp is directly connected to the Glow plug... You can run with A3 on a 20% nitro and still run in less that 220 deg f by making it extremely rich.. You rather not drive this rich, since the max performance you can get out by this is only 50% or below..
My suggestions are based on gettin the best performance out of your car with less damage..

BTW glow is not used just to start the car but also to make sure the car performs consistently. Please read an article about what the glow plug on your rc car tells you about your engine after a couple of tanks on it.. I can paste the article. if you can't find it..

It will depend on the capacity of the NiMh cell. A glow plug typically draws around 4A. A 2700 mAH cell would last a flying session, unless your engine is a sluggish starter, or, of course, if your sessions are very long drawn out! Anyway certailnly more than "a couple of minutes".

My answer is not based on research but on long time practical experience, albeit with aeroplane engines. With due consideration with your readings, have you checked performance with the different plugs? The plug type will afffect timing which may or not be critical depending on the application. I am in full agreement that you would need the "right" plug for optimising this. At the same time the fuel mixture, ambient temperature, etc. would also be of significance if you wanted to tweak to "maximum". This, in no way negates what I have said, so far.

For whatever it's worth, my little "research" has not shown up ANY reference to a direct co-relation with type of plug and engine temperature. Please do send  me any pertinent info on this. It's never too late to learn something new and of interest!

What I had found was that, the normal dry cells were of no use for starting the glow engines, where as  the humble 500 MAh Pananica Nicad always did the job. Never used a Duracell as these were not even availble then
Those were the days when a imported booster was a luxury and standard way to start was with a single cell. You had a short piece of single strand cooper wire attached to the plug. Hold the cell with one end of wire to any pole and touch the other pole to anywhere handy on the engine and go flipping the prop

flyingboxcar

Eveready used to make big 2V dry cells which was very much suited to our use. A normal 1.5 dry cell will not last even few starts.
Another way is to use a 3V or even 6 V with a resistance in line to give the required volatge at the plug. This was one of the recommended practice by engine makers. If you have an old OS manual lying you can this recommendation.

A 3V supply would work with a 1 ohm resistor in series. It should be rated at a minimum of 5 watts. Do note that this will get quite warm, if not hot, in operation. I would opt for a single NiCd/NiMh option.

Hard to imagine only a part of the plug glowing brightly. Try another plug of a different make/type and observe the result.

Hey,
It is a very rare occasion that this might happen. It could be a faulty glow plug, if it has come with car from factory. Never the less your car might still start if your tuning is right.

Hi Sushil,

Please follow the link below. I have no exp on 4 stroke engines and so i wont know about the working of a glow plug on them. I have only tried OS & enya plugs.. I love the enya plug since it has got platinum coil. It is double the cost of O.S but lasts 3 times longer than O.S and tuning the engine has been very forgiving.

Actually, the link shows you the effect of air/fuel mixture on the plug and head. A lean mixture will cause the plug and engine to run hotter than a rich mixture. It's the mixture that will influence the plug temperature and not vice versa.

This is not true in all cases. While this is common, you can have an engine that turns with hole(s) in the piston.  In many cases you will not feel the compression.

It stopped because, it ran too lean. This process is call flame out.. When is engine goes to max temp, the carb also heats up.. This ends in flame out..
Once your engine cools down you will be able to start it.. DONT run it lean.. Your engine wont last..

You can safely use SAE 30 Grade oil or your normal 2T lube oil (any brand available). All work, the idea is to displace moisture and any other byproducts of combustion from the metal inside the engine without damaging the rubber or silicon parts.
Even your singer (or other brand) machine oil will work but it does not stick on to metal parts for long and runs hence l have stopped using this one.
There are people who swear by WD 40 and then there are some who swear at it. Take your pick

thanks ANTA. BTW "speedracer" can u assure me that 2t oil is perfect for after run oil substitute..?

yup it will be really good plus ensure that there is no fuel left in the engine for that kill your engine by pinching the fuel pipe then remove it and without connecting the fuel pipe put in the igniter and start your engine this will eliminate even the last traces of the fuel then put in the 2t oil from carb opening and turn your engine one or two times that will be enough if you dont find time to run your car weekly during your board exams you can hand it over to me i'll run it (jokes apart)
just turn your engine one or two times even if you dont run it......do it weekly and add oil to it before turning and doit weekly.....

You don't need to give constant power to a glow plug .
the power is given via glow igniter just to heat it up after that the small spring in it will conserve the heat from ignition itself.

i just wanted to know... if you use hotter plugs, the motor as a tendency to run richer (considering the same tuning is used in both cases)...
also, you say that hotter plugs mean hotter engines... but richer motors run more fuel through so the the fuel itself has a cooler effect. then isnt the temp increase countered?

and what is the concept of after use oil?
