To be honest, I'm fairly disappointed with how this turned out. To begin with, the pegs used to make the joint is positively tiny, I'm terrified of snapping it while trying to turn it. Secondly, the joint now being lower on the body has offset the horizontal-alligning with the upper legs, and because the joints are so weak Skullsmasher is now perpetually sitting. Can't removed the balljoints to try and tighten them for fear of snapping the printed plastic. The idea was sound at the very least, since they work great in robot mode.
