The MMM was smoother, but, the MGM felt more powerful...IMO. When my 1512 1yF gets back from repair I will retest and post results. I am sure if I fiddled w/the settings I could get the temps down a bit w/the mmm. Also, not worrying about temps. w/the MGM made me drive the buggy even harder...:yipi: And there is something to be said for worry free driving....:yes:

How about the question from my previous post?

There was a drag brake on both controllers...don't remember the setting of the MGM, the MMM was at 30% I believe.
To lower heat on the motor I will reduce timing to 0, remove drag brake. Do you think that I can lower batt. temps. using the mmm?

Thanks for the testing and thread! I just recently had my money refunded on the MMM. I am saving for the MGM 22418. I am running a MM now and it thermals almost every time out and I run conservatively due to this. Would be nice to be able to put the hammer down and not worry about temps and other things. Keep us updated.
