My kit is a Tamiya TT01 with a spur- pinion of 58/23 and a Tamiya TEU 104BK with Tamiya brushed 28T GT tuned motor during my last 5 bashing sessions I already damaged 2 ESC what could be the problem ?
Are you drifting or running with grip tyres?
Are you running a heatsink on your motor? Not really related to the esc but worth knowing
What battery are you using and what ratings and voltage does it have?
