Just got my Limitless a little while back, car has ran absolutely amazing so far on the set-up I'm running. Started with a TP 4070 1700kv motor, Castle MMX8S ESC. Had an incident and rear center driveshaft first time running it gave, bent so bad it hit and ruined my motor. Anyways these passes running Spektrum 2050kv motor MMX8S and CNHL 90c 6s pack 117mph both passes.
