Well, since Medusa went bye-bye, I think they werent such high-priority anymore. Also, since most people seem to be ignoring feigao motors these days in favour of other similar brands with screwed on endbells ( hobbywing and similar motors like Dan Kerhsaw sells ), or the superior & well priced CastleNeu motors, there isnt much call for the heatsink clamps anymore. Sure, there will be some demand, but maybe not enough to justify the costs of the new extrusion mould and whatnot....
