[Mr V]

When we put our practice chassis together we had a "twitch" in our system too. We were not sending any commands to the DSC but the Talons signal light would blink and the motors would move for a brief moment. We switched to a different DSC and the problem went away. Opening up the DSC revealed that one of the chips had let out it's magic smoke. It was one that had been used in the past not a new unit, so it is hard to say when or why it occurred.
