I have a MMM and a 2200 combo in a Losi 8. The motor seems to get real hot to the touch. Dont have a temp gun to get exact temp. The fan on the esc Rarely comes on so the esc isnt getting real hot. Its all in a Losi 8 with a 48 tooth steel spur. I have a 13, 15, and 16 pinion and changing doesnt seem to make a difference in the motor temp. 4 cell lipo and settting on the MMM are brakes at 20%, 50% punch control, and 0/low timing. What causes them to run hot or is it normal.
