Stupid little part I made that attaches to make Classics Optimus scale better with Hegemon and pretty much everything else in my "CHUG" collection. I don't like chunky wide Orion near enough for what he costs, plus he's a bit too big, and Faith leader is way too big. My solution was to make this dumb add on part that adds a good 3/4 an inch to Prime's height without permanently changing anything at all. You just remove 4 screws in the back of Optimus, take the mid-torso apart and remove the legs, then put the torso back together and slide the new torso chunk on. The torso also connects to the swivel joint at the waist and keeps that articulation intact. You have to remove it to transform him, but I think it works for getting bot mode up to scale pretty well. Mine has a couple of other mods and some paint work done on it too.
I can dig it. I love Classics Prime but he has definitely become small for a voyager. This mod looks good with Hegemon and I agree that for some reason Orion is way too big. I was hoping Combiner Wars Prime would have solved this problem, but he is even bigger than Orion and looks horrible next to any Classics line. I'm still holding out for a 3rd party update...but alas I am happy with my heavily modded, no shield forearms Classics Prime
