If you want a ESC that can handle the 1527/1D in a vehicle, get a Schulze 40.300 which seems like the size of the car being used. I was right about what Patrick had said, "that the MMM can handle anything you throw at it". I know it can't and I don't know why he said that. The best option would be to just get a 1515/2.5D or 1515/1.5Y for 6S lipos and if you need more speed, just get a bigger pinion. You told me your diffs are the 4.3, I would switch them to the 3.3 buggy diffs. Keep in mind that you don't want to run your speed set up like you would a bashing set up. Things will get hot fast in a speed set up. Also, look into a data recorder like the Eagle Tree to see how many AMPs your set up is asking for. It's a great little device to have and it saves a lot of headaches.
