AA, I have no answer for why the MM would decide to cog... it's been very rare in these setups.

BUT, once it did cog that bad... something may have gone wrong in the esc... like fried caps or something. Try swapping out the MM and see if the porblem follows the esc or the truck.

I had a MM cog real bad once and after than it was a constant problem... it smoked something cause it was unusable after that even though it did continute to operate (never smoked literally). I still need to send that one in to get fixed...
