how do you swap the motor in ZZ clone??
 

since there are two wires attach to them. i would think the only way is to open the motor up, but it's kinda hard since it's so small. after i open up the motor then what? any suggestions?? please let me know. thanks

You don't have to open the motors up. You have to solder the wires to the end bell and to the case. The one that goes to the case you can strip the wire a little and just tape it on.
