the local hobbytown gave me a couple of their house brand hot glow plugs to try out, and report back to them if they were any good or not. i have one in my kyosho truck right now, and i love it. starts right up, doesnt flame out as easy as it would with an odonnell medium plug, although i don't know about the longevity, i only have a few tanks on it. ill post more when it burns out.
