I have the new emaxx and took it mud raceing and melted the moter so I bought a new set of 650's and they have always ran hot. Today I was doing donuts and melted them again, anybody have any ideas of what would cause this or fix this problem.
I wish I had an answer because I've been having the same problem.
I think I've smoked 4 or 5 sets of titans in mine. The Brushes keep coming apart.
One got hot enough to melt the fan and put on a pretty neat smoke show.
I have had the same problem with the motor in my slash.
I think the titans are a mass produced piece of junk.
I don't know what to say about the 650's you tried.
If you were continually doing donuts, then that explains why they burnt out. The e-maxx is a high demand truck, try adjusting your gearing in relation to the 650's power. Getting mud/crap inside the motor will for-sure trash them.
