R/C glow plugs are designed to handle less voltage and current over a short period of time. They will go up in smoke if power is applied for too long or if the voltage and/or current is to high. I have owned several nitro cars, planes, and helicopters over the years and I don't think a glow plug is going to be the holy grail for attys. Trust me on this one. I've wiped out hundreds of glow plugs over the years. Besides, glow plugs cost about $5 each; half the price of a new atty if you know where to
shop.....
