I have a problem I am hoping can be solved. For the second time now, my Bluebird BMS-630MG servo has burn out. They last for about 3-4 months. I noticed that while running the emaxx it acted like it did not want to turn. I stopped it and pulled the body off in time to see the smoke from the servo. There was nothing binding in the steering system. I have a Proline steering kit in it. With the horn disconnected, the steering truns very easily. What is goning on? I took the servo apart and the circuit board is toasted!
