will the 80mm medusa fit in an erevo?

i was planning on running a 6s setup. i believe hoov is running a 1515 1y on 6 cells geared for 40-45 with really low temps. that is really what i am looking for, high torque and low temps all day long. i was under the impression that a lower kv motor paired with higher voltage would run cooler than a higher kv motor and lower voltage. is my logic correct?
