randy,

i just want to see what hte difference is. I heard a lot of good stuff about ceramics, reducing rotating mass and such. But i want to buy a set of bearings, and not go thru all the measurements and stuff myself. so if anyone can offer a website that has a set of trf415ms quality ceramic bearings for sale, that'd be nice.

and ur new born trf415ms is the cutest thing. that aluminum servo horn looks cool, where'd u get it? does it get rid of the slack that the tamiya horn has sometimes?
