My friend and I both use the MM. They don't cog if you gear it correctly. I have posted this info on other forums. People have been buying low rpm/v Neu motors and putting flywheels on them for pinions with the MM. The MM has a hard time getting the vehicle started if it starts out in high gear. We have been using the 1512 1.5D and 1512 2D and a 1512 2D/H using 10-12T pinions with the 46T spur with our converted 8ight and MBX5 buggies.
With todays hot racing day, we seem to get better cooling from the MM by having some drilled holes in the MM TUB to allow the fets on the bottom side of the circuit board to allow some convection. It is the first time we have seen the NUE motor hotter than the MM after a race. Motor 159F with no fan and 143F on the MM with a 30mm fan on the top.

My calculations are mid 30's for that setup. That shouldn't have been a problem.
But it for sure sounds like a cooked motor. The speed control might still be OK.
Lehner will repair it, who knows what the cost will be. If it was that hot it might be better to just replace it anyway.
That really sucks though. A sweet motor like that down the tubes.
The MM wont like the Neu though.
