The KB45 is new. I went and looked at the pics (you made me wonder) and it does look funky in the pics. It actually looks normal in person. But the motor was new in the pics. From the box to the truck I got it the same week as the ESC. I have only run it on the LT-10s. The temps have never seen over 170 (168).
Thats not to say the motor is perfect....after all, we are talking about a $50 motor.
Everyone else that saw it run, and tried it out, said they thought it ran great. Everyone kept asking why I wanted to make it go slower...

I think its just me. I was able to get the MMM/Neu to crawl at very slow speeds. Which begs the questions...."why?" and "How often did you do this?"
To which I answer..."um ...almost never"
Everyone at the track seemed to love how it ran. The LT-10s and KB45 in the e-revo is a POWERHOUSE. I have never had a truck go from street to grass and not slowdown at least a little....but this went through grass like it wasnt there.
The ESC temps were always very low too. The highest temps were recorded on the caps hanging off the end. The most I could get them to go to was 130F. .....and that was getting the motor to 168. Batteries were never much above ambiant (90F)
Over all, when running normal, the ESC is great. I was just trying to soften the slow speeds a bit.
