This has probably been covered before, and I tried to search for it.
I should be picking up the Slash tomorrow after work. I have only run nitro engines and I can usualy get about 5 to 8 gallons from a motor. I am a complete electric noob , how long do these motors last? How can you tell it is time to get a new one? I've seen some guys with some kind of lathe thing at the track spinning the motor to shave it. It seems like black magic to me.
