Since you can't get it much worse, I am going to relate an observation I made a night or two ago. The brush assy on the drill motor is merely clipped in place by a small, plastic lever. This lever can be found by looking at the motor from the side, looking end on at the brush(try a magnifying lens). Between the wire terminal and the brush wire attachment you will see a small black lever holding the metal in place. If you carefully lift the lever, the brush assy will pop out. It rides in two slots like a drawer slide. I believe that most teams who have damaged motors have broken or melted this little lever and the result is a brush assy that will not stay in place.
I am not advocating that teams use this information to work around team update #7. It is simply an observation to repair a motor that might be used on a prototype or in design of a drive system. If heat is going to be a factor that could result in the melting of this lever, I would suggest that teams think about some method of holding the brush assy in place without interfering with motor cooling or operation.
