Unfortunetly I was not able to make it out to the track this weekend, but I was able to get it out on the street again hooked up to an Eagle Tree data logger. I have a nice flat area about 50-60 yards long where I can give it full throttle and full brake. With my tracking gearing I am usually able to hit 30+ mph in this distance. I checked for clogging from a stand still, and noticed that sometimes there was some slight clogging, once the motor was spinning it was smooth and powerful. I made 6 runs (full throttle/full brake) on paved road (100% traction) and then checked the temps/Eagle Tree data. The ambient temps were about 70 degrees, I checked the motor and it was 103 degrees, the ESC was 98 degrees. The Eagle tree showed it was drawing 140amps (max). Those numbers looked normal, but one thing happen that was strange, while I was checking the Eagle tree data I heard a fan whirling, I looked and the MMM ESC fan was running, I double checked the ESC temp and it now read 93 (cooled slightly), after a second or two the fan stopped. I understand the fan is supposed to come on at 140 degrees, but my ESC never got over 100 degrees, don't know why the fan came on. Will need to keep an eye on the temps when I do get on the track.
