Same. In 2011 we tested all our 775s and at the time of installation they were good. Over the competition season, we developed case shorts, resulting in us lying dead during a large number of matches at GTR-W. Robot would start autonomous, and when the arm hit a certain angle, we'd cut out for about a minute.

2056 helped us troubleshoot the case short, and loaned us a "775 blaster cable" that allowed us to temporarily clear the short. It got us through the competition.

I wouldn't touch a 775 again unless the case is electrically isolated. Mounting to lexan, and plastic 1st stage gearing is a good start.
