Idk @bill_delong can probably explain it better than me.
I mean, for drag would you want a torquey or speedy motor? 🤔
You can always but higher turn motors in there. Maybe like a 6.5, 8.5. 10.5. 13.5. 13.5 sensored will be the most accurate power to stock 3300kv sensorless. But it all depends...
Same size motor as stock which is a 540 so thats all good.
For that low turn of a motor, yes you will need a esc upgrade. You ideally need something that is 160A+. XR10 Pro / Pro G2s might be one to consider. Yes its a low turn motor, which is high kv. So it won't be as torquey as the stock...
