Upon continuing my work on the diffs, I noticed that the Red motor wire was not soldered well. If you jiggled it attached to the motor mount, it was snug but once I removed the motor you could tell it was not completely secure. I hope this helps also to lowering the temps. While I do agree that 175 is ok, I would rather be in the 140-160 range for my likings and efficiency. When I was running the MMM combo, it was the heat of summer and it ran under 160 all the time. It was extremely fast probably too fast and I really liked the idea of a sensored motor so I switched and ran semi indoors in the winter. And as far as tire/traction there were several other E-truggies running revolvers but I kept going back to bowties for outdoors. On the standard offset rims now, I am running AKA I-beams since they don't make bowties for 2.0 rims. My next tire purchase will probably be AKA City Blocks since I hear so many good things about them. I am going to run tomorrow to see what kind of temps I get and I will post them for you guys tomorrow night. Once again thanks for all the replies. It is people like you that make the hobby less frustrating and keep it alive.
