I recently purchased a new Tekin RX8 Gen 2 and a Pro4 4600 motor for my SCTE 2.0. I had the local hobby shop solder it up and installed them. Unfortunately, I am having issues with the low end of the throttle. The motor is stuttering badly, the wires to the lipo, the rx8 gen 2, and the motor are getting quite hot (140+).

Once it gets past the low end of the throttle, it works fine. I am either full throttle or stuttering badly. I rotated the motor in neutral and the three sensor light are working, so it is not the sensor cable. Occasionally, the motor just buzzes instead of stuttering.

Any ideas? or should I just send the esc in to Tekin?
