Well, I guess it seemed to good to be true. My new Challenger came to a screeching halt today... quite literally. I was operating it on DC, just watching it chug around the layout quite contently when all of a sudden, the squealing brakes sound effect kicked in and so did the momentum stop. After it had come to a complete stop, it did a nice little steam blow sound and just sat there. I thought, "hmmm that's weird", and turned the throttle off and back on. Nothing. So I turned the power switch off and back on and then applied a little throttle. Not only did it respond, but it did so as if it were on nitrous. The chug chug sounded as if it was doing 200mph even though the engine was doing a scale 50mph or so. I then hooked it up to DCC to see what the hey and all it wanted to do was sit there and click or run at top speed. Called my LHS and they told me to bring it in tomorrow so they can "have a look."
