Hello, I bought a 60052 set for my son. It worked fine the first day. Today it would not move. Changed out the Duracell batteries for new. The remote lights up green, when the dials are moved. The batter pack lights up solid green. The IR receiver is solid when not moving the receiver dials and flashes when the remote dials are moved. Both the remote and receiver are on the same channel and the receiver light flashes on all 4 channels. Any recommendations?
