no im on heroin... kidding but no i am not just gonna put a sidewinder in there to see. thats why i was asking. and i didnt know running a 3s on a mamba max was pushing the limits? in a revo its tough sure. but with a bec and not geared for more than 40mph...
Put a fan on the sidewinder. I have one in a pede and it seems like a good esc, not sure how well it will do in a revo. Gear it low, like 30mph and give it a try. Good airflow is a necessity...
