"Emax motors are often sold in a bundled set and all four motors can come in CW or CCW and may not arrive with two CW and to CCW. This is not a mistake but rather a decision made by the mfr. to package them this way. This does not impact the function or reliability of the motors as they locking nuts keep the props in place. I always recommend that loctite be added when using motors that are all fastened in the same direction." ~ Tarek Maalouf
