It's a bummer if your glow driver dies on you. I was running one of my RC cars one day and found I had both of my glow drivers
but both were dead. Luckily I had a piece of copper tubing that fit over the glow plug post and a loose AA battery. Car engines have big heat sinks so the plug is recessed way inside the head. It worked well enough to fire the engine off to run 3 tanks. That's something a GlowHead would do.
