FYI: It's not the number of poles per se that the MM has trouble with, it's if the motor uses a slotted stator (basically means if each coil is wrapped around a metal "core" as opposed to an "air core", like the Feigaos). Neu motors and the Novak motors are slotted stator motors, so both can have issues with the MM ESC. This can be overcome with some conservative gearing and/or changing some of the settings in the ESC though...
