Today at the races, my dx3.0 was working then quit. Th rx is an sr3000. i went over and had no signle to it what so ever. i rebinded(took 3 time) and it ran for about 3 min and stopped again..same issue. i put my other sr3000 in and it worked fine all day long. The 1st rx was used last sunday all day long with no probs. didn't do anything during the week. Any ideas? Take it apart and clean/ check the wires? I bought this in dec 07, should i be having these probs already?

Thanks
Bryan
