two fast questions!!!

I have had interference issues, but those were with cheap chinese becs. I just moved the equipment around till it went away. Braiding the motor wires does seem to help, as does keeping the low volt signal wires away from the large leads.

I would say that the mm overheated on the 8t on 3s due to too much load. I guess you regeared it when you went to 4s? More voltage, less gear, gives you less amp draw and the same speed. I bet that lowered the amp draw considerably. I run quite a few larger vehicles on 4s and they can easily pull 140 amps for a few seconds. I can only imagine what that 1.5d was pulling on 3s. Suprised that you did not kill a battery!
