Glow Plug Recommendations
Its been a long time since I ran 1/8th scale buggy, and I could probably find recommendations on the web, but I think I trust you guys more so than whatever google search brings up. I'm trying to brush up and prepare for the next racing season. I would like to know what plugs people run nowadays on the following engines.
Werks B3 TL Pro
Werks B7 TL Pro
Sirio Evo 3 STI
Mach 26
Any suggestion would be appreciated.

Here is a guide that will tell you what hot plugs do for you.

HOT PLUGS
So what is a 'hot' plug, and how does it differ from a 'cold' plug?
Naturally, a hot plug will heat up faster and stay hotter, but that's not the whole story. When discussing this aspect of glow plugs, another very important aspect must be considered, the amount methanol in the fuel. The more methanol we're using (i.e., less oil and less nitro), the hotter the plug we should use. Conversely, the more nitro and/or oil we use, the less methanol we're using, so we use a cool(er) plug. An extreme example would be when using a very high nitro content fuel in a very high RPM engine (a typical ducted fan engine, for example). Here we'd use a very cold plug. For most sport pilots using fuel with just 5-15% nitro, however, a hotter plug would probably do well.
RULES OF THUMB TO LIVE BY
* Use a hot plug with low nitro (less than 24%), and a cold plug with high nitro (more than 25%).
* If you remove the glow starter from you idling engine, and notice an immediate drop in RPM, you may need a hotter plug or more nitro.
* If your engine has a tendency to backfire a lot, you may be using a glow plug that's too hot, or you may need fuel with less nitro.
* Most hot plugs can take up to 2.0 volts starting power without burning up, while most cold plugs prefer 1.2 to 1.5 volts starting power.

i found that the hotter the plug the easier the tune. I would run a p3 for turbo or mc59 for standard.
