I just bought a XTM XT2 that came with an Airtronics MX-Sport radio. When I was breaking it in I lost all control of the car. At about 40 feet a way I lost steering and breaks and the car nosed into the curb. I kept the breaks applied as I went to retrieve the car and all of a sudden the car went all out. It jumped the curb and went into a wall at full speed. When I got to the car it was functioning normally. The throttle fail safe was even working when I checked it. Does anyone know what happened to my signal?
