I just got a 120a ESC and just fried it in less than 5 mins what is really going on I geared it down too 85t spur gear and A 20t pinion the motor didn't get hot and the ESC didn't get hott either it just started smoking .... I don't get why it started smoking the fan still works and the steering but won't move forward or backwards this will be my 3rd ESC.... Is my 3s lipo battery too stong for the esc??? It's a ArrowRC PRO LIPO 11.1v 5200mAh 50C and I have two 2s battery's one of the 2s is a venom 7.4 5000mAh 25c and a 2s powerhobby PRO LIPO 7.4 5200mAh 50c.... So is the 3s LIPO battery to strong????
