I bought a used reedy 8.5 and it seemed to be fading in the last race. I am running it in a Dex410V3, and they are notorious for hot motors because of how tight the body is, not much room for heat to escape. I did make some cut outs to improve air flow in front of the motor. I am temping 140-150 so that sounds good. Does it really help to put new bearings in, or would it be best to plunk over some money for a new motor? I did not check the esc temp.
