I'm under the impression that these motors run hot in the frist place no personal experiance though. I've done a search for Medusa I'm guessing you mean 36-50 4600kv not finding many for sale. and wondering why you feel a 3300kv wouldn't be a better choice. my current setup is Traxxas 3500kv motor, Traxxas ESC, 13/52 gearing 2s 4500mah 30c Flightmax either stock tires or Proline Calibers.
