Yeah, the other thing that looks strange is it looks like the copper around the commutator separated a bit and caused more grinding? I couldn't get my motor open to look but does this makes sense? It continued to grind and spark out of the water. I'm a pretty big noob when it comes to motors so I hope I explained this well enough.
Yes, running the small 9v battery seemed to do little harm. In the video linked, the guy uses and 7.4 lipo so I though I'd give it a try.
Once I make this video, you may be able to see what I'm talking about in terms of the commutator separating.
