Other controllers have no problem with motors from 2, 4 and 6 poles. The MM worked great with my Align 600L motor and someone is even using a Quark 80with a Align 600XL. To me it seems like a good excuse to go with. Not everyone has the money to buy a Neu motor and they stick with a Feigao for the price. I use feigaos as well and haven't had problems with them.
