Novak motor questions

[lincpimp]

Just wondering how good are their motors? Are they better than the feigao motors in terms of effecientcy? I was looking at the 6.5 hv motor and the 13.5 motor. They are both around 3000kv so good for 3s. I have read that they are similar to a 380 size motor internally. Just looking for a motor upgrade for my stampede as my 12s feigao tends to run slightly hot. I would be using the novak motor with a MM, sorry do not want to buy a novak esc.
