Glow Plugs

[sinesthezia]

Alright, so I went over to the hobby store and the woman sold me the Duratrax Gold Racing glow plug. $5 which was kind of pricey, but it was the only kind she had for my car.
Anyhow, I came home and went onto Tower Hobbies and was searching around for a hopefully less expensive glow plug, and now I am in a bind.
There are so many kinds and I am assuming that different kinds of glow plugs are for specific types of engines...therefore, since my car has a two stroke engine, would any type of glow plug designed for a two stroke work in my car, or do I have to constantly buy Duratrax brand glow plugs? My boyfriend flies a plane, and it's engine is a two stroke, so would the glow plugs he uses (Tower Hobby $2.99 brand) work in my car?
These seem like silly questions, but I have absolutely no idea.

By the way, thanks for all of the helpful suggestions from my last post.
I am going to go buy myself a new glow plug starter today and hopefully get my car fired up by this afternoon.

what motor you have? did the Duratrax glow plug say anything about being a Turbo Plug? if not then i d suggest you buy some McCoy 59s and/or OS #8s.

Well, the long and short of glow plugs is, you can use different brands. However, there's a few "gotchas". Typically, "Turbo" plugs (the type that do not use a copper washer, and have a taper at the combustion-end) are usually used in the higher-end motors, mostly On-Road. These plugs are numbered like P6, P7, etc. They are NOT compatible with non-turbo engines, and vice-versa, as the Turbo-style plugs/engines use the taper at the bottom of the plug to seal the combustion chamber.

That leaves us with the non-turbo or traditional style plugs. These plugs usually come in two lengths, medium and long. The only real differences here are the lengths of the plugs, and not the actual thread pitch or diameter.

Now, regarding using a long plug vs a medium plug... It really boils down to what your motor calls for. If your motor calls for a "MC59" or "MC6" plug, it uses a medium length plug. Typically, OS uses the longer plugs, as do some OLD traxxas engines, and some older Ofna/Picco engines.

Typically, non-turbo OS's use a longer plug, like the A3, for example.

Lastly, idle bars. These type of plugs are almost always used in aircraft engines; never in ground-based engines.

Now, as for brands of plugs that market a MC-type plug; Dynamite is one brand, HPI, and Associated all market the MC-type plugs under their brand names.

It can be confusing, but keep in mind, the average plug is a Mc59. Stick with that, and you should be alright.

No it didn't say anything about being a Turbo...the engine is a Supertigre G-27CX .27

Thanks for the suggestion!

looks like that engine uses a medium length glow plug.

Also, if your boyfriend flies planes, don't be tempted to use the same fuel. Cars and planes have different demands for their fuel. Airplane fuel usually has less lubrication and will probably cause your Raze engine to burn up. I find a good fuel with a 20% nitro blend. any brand name for cars is usually good.

Your stock glow plug on that engine is a duratrax "carbon" plug (grey in color). The gold ones are for higher nitro content, but should be ok. The plugs the other people here suggest are good advice, too.

Excellent point; I second that completely. Not only are there different oil contents, but usually a lesser nitro content as well.

Oh no no! I was informed right off the bat that airplane fuel is not for cars, so don't worry. I have a nice big gallon of fuel just for me.
