I think something is at a very low clearance and that the plastic cover changes shape if overtightened causing it to come in contact with one of the gears. Any chance your mini is 12.75:1?
Yup, a Toughbox Mini. It is set at the standard gear reduction that is detailed in the assembly manual. If I remember correctly, it is 12.75:1 or something similar. We can try that tomorrow when we unbag the robot at state. Did it sound similar to what it sounded like in the video I posted?

6. Keep track of team updates, Q & A responses and FIRST blog posts
7. Be active on CD
8. Plan and execute drive team strategy
And more that won't fit on this list...
