Hi I finally received my robot kit but I have a few problems. First of all, all of the standard servos don't work. The continuous rotation servos are fine but not the standard ones. I could hear something in the servo but it would't move. please help me! It is stressing me out! stress I also have a second problem. The battery pack, as I turned it on it quickly became incredibly hot. It even melted the plastic. I don't know what went wrong everthing else was fine. Please reply I am running out of options. right now it is peing held up by electrical tape, but I want to know what caused the problem. confused
