Been using a traxxas link radio I got with my slash 4x4 in my sons 2wd slash. I went to replace the speedo in his truck with a brushless one yesterday and I couldnt get the esc to calibrate so I tried it on the steering channel which worked fine. He was driving the truck with no issues 5 min prior to me changing esc and for the last few weeks with no problems. I tried putting the old esc back in but still no response from ch 2.

Anyone have an idea of what could be the issue or am I doing something wrong. I have reset the radio 2 times, re bound the radio and receiver, put new batteries in it, ect. Have even opened the radio and receiver up and see no broken wires, burn areas or bad soldering joints. Getting frustrated with it and plan on calling Traxxas in the next few days to see what they can tell me.
