Also, make sure you have good airflow to the motor, you are running 0 timing, and you are smooth on the throttle. The number of oscillations that your finger moves back and forth per lap ideally would be equal to the number of turns plus jumps on the track.

Recently my 1900 ran a 30 minute A-main with one battery swap. I finished 2nd and motor temps were 134F. After a 10 min main in a small indoor track temps are between 115 and 123. This is all because I follow all of the rules I mentioned. Others running tekin motors in the same race seem to get temps at least 25 degrees warmer.
