I was just wondering if anyone had the answer to this.  I am new in this whole rc thing.  I traded for a used monster mt and I am having a problem with it.  When I first started it up, I gave it gas and it had to pick up speed.  Like a bad clutch in a car.  The second time I started it up,  It does not move.  It runs and the fan wheel moves like it is supposed to.  Does anyone have a idea on what is wrong?   Thanks New Guy
