Nice packaging, have you send me additional packages?

Hi... not to barge in... but I had the same problem with my 12020 and 8Xl setup just last night.. a couple days ago I ran the truck without the cover and flipped it.. the motor made good contact with the ground (concrete
) and bent the motor mount... at first, the motor would not rotate by hand, then all of sudden it did..
Then last night after a little clean up and a change of the motor mount.. I plugged everything back together and did a test... the motor started cogging violently, then I saw the shrink on the 12020 started to tear away.. I pugged everything out, and found that the temp on the motor and controller was very very high..
I went to the BK site to see if I could find any info that would explain what was happening... and I found this:
"Interruption of one motor phase
Motor does not rev up, only jerks back and forth. Disconnect battery immediately, motor can be severely damaged!"

I opened the motor and notice the magnet was making some contact with the
the coils... the bearings also felt a little rough..
Just my 2 cents
Alien..
