Do we need 6-8poles motors for 1/8 ep?

Brian what do mean by" Another consideration is that the more poles a motor has, the more the ESC has to commutate and may hit a rpm limit"

u meant the esc can't handle the rmp or amp draw?

The brushless esc manual will often state a max rpm for 2/4/6/8 pole motor

The max rpm for a 2 pole will be higher than a 4 pole and so on....

So an eight pole may be limited to a small max rpm value depending on the esc.
