My motor only runs hot because I live in Chandler AZ, and its like 103F during the day. With a fan the motor would run great. On 6 cell nimh it just as fast as a stock e-maxx, on 12 cell nimh it hauls. With 3S lipo you would get great run times and speed.
PS I really didn't want one at first but after I my buddies I changed my mind. :)
