yeah they ring like church bells but from new they were super smooth with no bind and perfect mesh...no sloppy parts here...i think it's the steel hardness that must resonate, and apart from the a and b gears everything else is helical even the spiders in the diffs...I guess when the ringing stops I'll know there's a problem somewhere

and 46u is correct the NMT is still being tested...surprised to hear the fuego is in stock already as it's the megaMT with smaller wheels...everything else is identical
