Okay so im on facebook and i see one of my friends is parting out 2 blasters and 300ex so i ask him whats all in the blasters and he says their mostly stock but one has a mr.250 motor on it. I was like what the hell i guessed that its was a rm 250 motor and i said how much for the rm 250 motor. he says it a mr.250 motor for 50 bucks anyone ever heard of these ? if its not blown up i might scoop it up.
