yeah I think 5055 motors are fine for torque and speed. With DIYeboard ESC, the speed and amps have upper limit. But, bigger motors have stronger torque even within that limit. In real life it may not make much difference. But, I like the look of two big ones down there lol.
I’m using 15t/36t ratio. Probably same as yours but my motors are 180kv. I’m not sure how that factors in performance because the ESC runs FOC and no real ERPM limits.
