Many years ago I also used a panel glow plug wire. It seemed to work too hot even on the lowest setting and I would constantly burn out glow plugs. To make a long story short, I now only use a glow starter like Hobbico's Hot-Shot and never have any problems. In fact, the panel's plug wire would sometimes get in the way of the prop. This was a real pain! The glow starter is really worth the small investment of about $15.
