But we aren't buying UL listed motors, are we? We are using motors that are factory seconds or discontinued items that have been donated (or sold at a deep discount) to FIRST.
I'm not defending Banebots. This case shorting issue is not acceptable. However, you get what you pay for.
BTW, please check with your electrical lead mentor before attempting a DWT as you need specific test equipment and the test degrades the insulation being tested.
JMHO,

Well, we paid $5000+++ to enter a competition that limits us on what we use to certain items. I'd prefer it if those items weren't faulty. Just sayin'
