one thing that makes me giggle is the 5200 coil. Notice how the coil has been unwound from the original OEM build from econowind. TC used to unwind the coils on all their drivers in order to get a shorter overall coil length //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif You can actually see where someone at TC took a razor blade and commenced to hacking on the former //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif
Also two big differences in the SJA type coils is that the APXX only has one spider and the RD SHW has two, plus the SHW has another layer of varnish on it.
Interestingly enough, all three coils fit the same motor size, so they're all interchangeable with whatever motor. neat huh?
