cracked rotor on velineon

hey on the medusa motors, I was testing out my new kokam h5 4000mah 3s pack after 20 minutes i was getting bored so i was pushing it hard trying to make the pack dump lol i pulled the car up there was a twig in my motor cooling fan i was like crap better check the motor and to touch it was just warm.

I have to say that also the efficiency of this medusa 3300kv motor is great as well i was getting 18 minutes out of my 4s a123 whereas my plettenberg extreme was only getting about 14 minutes geared for the same top speed and bashed the same.
