Run 20% in it and it'll be good, that's all I run in my GT's which I had one out today and runs like a top! The toasted glow plugs will happen, I just broke in my buddies VTX truggy and it burned 2 plugs up also, but they said in the manual it would cause of break in! I think you'll like the Firestorm, I had a HPI Rush and it took one hell of a beatin! Have fun with it!
