Get with Armma Support if it's still under warranty and they will get it replaced. The 180 ESC has been pretty much proven to be rather faulty, luckily Arrma has always been good about replacing them and now will typically give you the 185 instead which is MUCH better than the 180.
I called them and they told me to send them in to be repaired are replaced. Well the motor needs to be replaced for sure. I hope they do send me the updated esc and motor.
