Took the center Smart diff apart to check. It had plenty of grease, the grease was still semi-clear and the gears, ramps, etc. still looked good. Have three race weekends on the diff. I have a Tekin T8 2000kv motor on the way and I will try that with my MMM ESC in a sensorless mode to see how it compares to the MMM 2200kv motor.
