I can't find the one that has a specific power panel schematic and parts list at the moment...

http://www.uoguelph.ca/~antoon/circ/circuits.htm Has several circuits, some of which could be modified into the glow driver.

If I remember correctly... they are using a pulsed 12 volt to do the glow, as the resistance form of voltage drop is power-hungry and produces a lot of heat.

The simple resistance circuit would be a primay resistor of appx 8 to 8.5 times the resistance of the glow plug... and then an adjustable resistor to adjust the current. The nominal 12 volt gell cell, just as the nominal 1.2 volt NiCd actually reads higher when fully charged. The Gell cell will be close to 13.8 durring most of its useful charge. That's close to 10 times the 1.4 to 1.5 volts seen from a NiCd durring most of its useful charge.

The circuit used in the power panel is simple... and has been published in all kinds of places. I just can't find a link to it at the moment and my favorite RC gadget site, which has it, (linked fron the above...) is down right now.

The better site is up...

The glow driver circuit is listed sepatarely from the power panel... The panel assumes you built that circuit and are sticking it in.
