I am sure this has been asked somewhere but is there a list of motors that are equivalent to the one in the power pack c? The naming convention on these motors are inconsistent. I am currently building the x29 and it recommends a park 425 equivalent, 1200 kv using a 4s 2200mah battery. I ordered a motor and then realized it may not be the right size (see picture). I did some more research and found a suppo 2217/7 1250kv motor, which sounds like it might be the right size but it only recommends a 3s battery?
