That's gonna be hard to control with that much power. Even with the mid motor conversion it'll parachute like crazy above 60mph. I think you're in for some challenges. Good luck.
You're overthinking it, man.
You've gotten some top shelf advice from a couple guys who know their 💩 (not putting my own name into that mix, by the way). They've already done the work on this. Reinventing the wheel ain't cost-effective. You should try their advice and get some trigger time in...
I prefer bigger cans and pinions to keep the voltage and temps more in the midrange. I know my firma and blx esc's are kinda nerfed at high amp draw, so I try to find the top speed of a certain gear ratio by working up to it without triggering voltage sag. And by paying attention to the temps, I...
