Replacement motor for an HV max

[pipeous]

My friend just roasted the motor in his emaxx, he had the 4.5 running on 4s lipo. It was a new system so he'll send it into Novak. I know Feigao sells sensored motors but I am not sure what the models are that would be similar in size. I know of the sensorless xl ones.

what motors are a good replacement and a lower kv would help too (or he better run 3s hehe)
