with this prop, motor came down barely warm even after 3 non stop flights so if not the torquing, i would definetely try a 14x7..
What brand prop are you using? Torque roll effects really have as much to do with the weight of the spinning disc as the diameter. So you may find an APC 13x6.5 would have more torque effect than say a Xoar or Vox 14x7, since they are a lighter prop.
