Motor braking.

Yeah, exactly. Does it have enough diodes though for this?

I just tried out motor shorting with drill, i used a 3/8 drill on 7XL, all I did was popped some 5.5mm female plugs on motor plugs and held them together. I spun the drill up and then pushed them together, good spark, but rpm's dropped by about 40%, which is alot considering. It was hard to hold onto as well. The motor was slowly getting warm, I did it for about 10 seconds. The connectors were getting very warm, almost hot, probably because from the resistance from them touching only very little.

Also, when I stopped the drill, it stopped almost immediately, normally is spins down a while...

From what I observed, it was far more than enough to flip a MT over, and easily stop it.
