Ok thanks for the tips. One reason I was preferring the HW 4000kv motor in lieu of their 3300kv was because I already have a Reedy SC600 ESC & Reedy 3300kv brushless sensorless motor combo that came in my RC10T4.3 rtr. Idk how much of an apples-to-apples comparison the Hobbywing 3300kv vs Reedy 3300kv motors are, but I was thinking I'd like having the different kV rating variety.
