The jaguars didn't exactly break. They would work intermittently, which is in some ways worse. I'm not exactly sure what the problem was. Scott was noticing that the problem was getting worse and worse as the qualification matches went on. We finally correlated that during a match, Scott hit the wall and pushed against it in high gear for a tiny bit to grab a ball. When he tried to back up, one drive side immediately started acting up. It seemed like the Jags had trouble with the momentary high current draw that was caused by pushing against the wall, and then waited for a second or two before coming back to life. So, we'll be using Victors in our drivetrain and with our other high current motors from now onwards.
