Turnigy Glowplug Driver.
The perfect tool for lighting the glowplug in your nitro engine. Simple to use, just add a alkaline "AA" size battery or Nimh and you are ready go. The glowplug driver locks onto the glowplug so that it will not keep falling off as you are starting your engine. The case is machined from aluminum and has a screw cap for easy installation of the battery.
