Both of the cases were the problelm of the motor sensor. If both of your NOVAK motor can ran without problem with the same ESC, it is the sensor on your X12 motor.
i too have the sam problem / x12 6.5 t w/ other esc like viper, mamba max pro and tekin. it is thw motor sensor. mine was brand new with 2 runs. i thought it was my speedo but all have the same problem. oncw u put lpad on the motor, it feels lime u r in sensorleas mode. btw, stop using that motor asap. i burnt my gt 2.0 by ignoring it. not good
