I just made my own for a ST2300 engine that was giving me a headache, now the engine runs much better and after many flights the glow plug seems to be in good condition. Here is what I did, I connected a 2200 mah Nicd battery to a switch and from there to the engine. One cable attached to any screw of the engine (ground) and the positive to the glow plug. Be aware that the glow plug draws around 2 to 3 amps.
