You use it to ignite a glow plug on a nitro vehicle which allows the engine to start the combusion process and therefore start running.

So in other words you have to ignite the glo plug before you start the vehicle.

hehe. Welcome aboard Mach! :D

First, understand how "glow" engines work: they burn on a mixture of (approximately) 60-70% wood alcohol (methanol,) 10% or more nitromethane, and 14-18% lubricants. The "spark plug" is called a glow plug. It has a tiny coil in it made of thin wire. Once the coil glows hot enough to burn the alcohol/nitro mixture, a catalytic action between the alcohol/nitro mix keeps it glowing red hot and keeps the engine running.

To get this process going, a glow starter with a 1.2 - 1.5 volt sub C size battery cell is connected to the glow plug and the resistance of the coil causes it to glow a bright yellow-red, hot enough to start the engine.

Here is a pic of one (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLN91&P=ML).

The little "meter" at the top of these is **supposed** to just let you know you have a good connection to the glow coil. The glow starter is applied to the plug with a slight push-twist and is removed as soon as it gets running.

Yeah, those meters hardly ever work... :rolleyes:

BTW, his name is Speed Racer, his car is Mach 5! :D ;)

They also have clamp style glow ignitors. :)
