At this point, I'm now thinking that even the 8XL is hot a motor for the MM on my Muggy. Maybe I should get a 9XL. On the other hand, I did get to run the Compro when trying to get it programmed and it didn't have any trouble running anything I threw at it. 5S with the 7XL with higher gearing than I would have attempted with the MM and 8XL. But for the fact that I couldn't program the Compro, I would have considered it a good replacement for the MM.

I still like the MM in relatively light vehicles, but I think that a real MT controller is called for in anything heavy, say over 12lbs.

i would agree, but I'm cheap! lol

Hey, I'm cheap too. I prefer the term "frugal." That's why I consider the MM such a value. It can do so much, but it appears that I, and perhaps others, are running the MM on the ragged edge of what it can take.

I believe your problems stem from the big tires and near direct drive situation, I run mine in a Gmaxx and G2R gorilla conversion, bot with trannies and they get hot on long runs but haven't burned one yet. this summer i need to put fans on them

There's no doubt that my problems are the result of the gearing due to the tires, weight, etc. I'm sure that if I had this setup in a lighter truck, I wouldn't be having any problems at all.

I'll get the Compro back sooner or later. Maybe I'll luck out and Mike will let me trade it for something else, since it is brand new. Either way, I'll get the right setup. I've gotta tell ya. For those few minutes that I was able to get the Compro running, the performance far exceeded anything that I've been able to pull out of the MM in my Muggy. The Compro ran so cool that I was able to really start getting on some gearing. IIRC, I ran 14/46 with the 40 series tires and it was on the borderline of stupid. The power, for me, was almost unimaginable. If I can get the Compro running right, I think I might even get to like it, inspite of the reverse issues. I found the programming easy and there was zero cogging.
