Re: Banebots RS-775 Case Short

781: How many RS-775 motors were on your robot in total in 2011? What we ultimately found to be the cause of our robot dying on the middle of the field at the Florida Regional was that we had a pair of RS-775s that became case-shorted at a certain spot in their rotation over the course of competition. It was frustratingly hard to reproduce in the pit. Our theory was that when both motors were case shorted at the same time (e.g. bad luck), current was able to flow between them. This added draw lowered the battery's voltage and caused reboots.

Since this thread has been bumped in 2012, it is a good time to ask: Has anyone run into case short issues with the 775 motor purchased this year?

Regardless, thanks to the best motor rules in years, we will be avoiding using RS-775 motors for the foreseeable future.
