Tim, thanks for your input. On-line I just discovered an OFNA Plug Driver that appears work off of 12v, and has only the weight of the connector on the glow plug. I'm going to see if one of the local hobby stores can get one of these in for me to try. Otherwise, I'll order one via the web.

I believe that I'm understanding more and more why this years venture into wet power from sailplanes started with two cycle gasoline engines. I have no idea why I thought that small airplanes with glow engines were a good idea...

Fly safe, Glover
