Has anybody opened a Mamba Maxx motor?

One of the screw heads broke off. It's going to require a very small easy out. I wonder if they make them that small? Or, maybe just dill on it a little, I guess. There is still a very small amount of sand still in there that I'm going to need to get out, but on a better note maybe that is why my controller is acting up. It is getting real hot real fast and then shutting down (something has that slight smell of smoked electronics hopefully it was from the fried lipo). I'm going to try it tonight with a different motor.
