New motor or repair Kit? 2200kv

[togepipro]

It burned because I continue use it after I hear a grinding sound, I was thinking that the sound come from the transmission, never goes in my mind that the sound come from the motor. I'm going to borrow a motor to check is the MMM is ok, but 0 smell of smoke on the MMM and the start up is ok.

So, I'm going to start looking for a 1518 or 1520 on ebay... I like to put a 1717, but is not possible with mayor modifications or someone know how to resolve the motor mount issue ?
