I've had my eye on an SCT410 2.0 for a while now and have some extra electronics laying around, one of which happens to be a 3668 motor. Does anybody know if this will fit in an SCT410? I'm pretty sure a 3660 will fit, but not sure if the extra 8mm will be too big. I'll likely upgrade to better electronics later, but figured I'd use what I have if I could save some money up front. Any help is appreciated. Thanks in advance.
