Im having problems with my SI-4431 servo in my SCTE 2.0. The servo is only a few weeks old and has only been ran in the truck for 15 batteries. A couplke hours ago, I was at the track, the only thing I did was make a few changes to my HW V2.1 via the program card. Once I was finished, I went out on the track and had 0 steering. The servo is not making the normal initializing tones. I checked my RX with another know working servo and everything is fine. I need to know how I would go about getting a replacement 4431.
