"The smoking gun" I mean motor!
In my humble opinion, I try not to get the motor any hotter than 190 deg. F.
Once you get above that, you start to smell of melting electronics. I normally gear the motor to lap times and the temp. usually doing it this way doesn't go much over 180.
If you want to go fast you will have to push the motors close to the limit to be competitive but not go crazy and smoke the motor either. There is that fine line that you don't want to cross! I believe 190 is that line!
