Boys. I solved the problem. The rover works. My settings were all right. The problem is the esc, basically during ignition, the esc expects to feel the gas halfway, 1500micro seconds… But this has half come when you connect the radio to the fc… This delay causes the esc to not start properly. If I start the rover with the esc off, wait for calibration, the radio connection is start the esc, everything works fine.
In practice, for all this time the vehicle was working correctly and I had not understood it… In practice, for all this time the vehicle was working correctly and I had not understood it… 
Thank you all very much for your help. Now I have to open another post to understand how to set an external LED.
