MCSm Mk II - Inner Frame
It's been a while since I've done more than with this inner frame than just tweak my existing models, so when I decided to start on a new one I felt it was past time for a revamp. The bricked version is coming soon (I hope), but I'm pretty pleased with the changes I've made to the IF.
Ball-joint-based hips mean enhanced stability (especially compared to the old tap/clip based ones) and padlock plate-based elbows offer a new level of articulation in the arms (though at the cost of wrist rotation). The lower legs, shoulders and torso are unchanged from the original.
