I think the general consensus about CW Optimus Prime is that his head is kinda small. I've seen some attempts to swap it out for a new head (Kreo, Shapeways), but none of them have seemed to hit the right proportions. Anybody have any ideas about a good noggin for Prime here? The main requirement here is that I want it to still transform, and I want the proportions to work the the figure with no extra upgrades.
The problem with CW Optimus is that the head flips around sideways for transformation. It needs a low clearance to be able to flip. Not sure there's any good replacement. Some people have made shapeways heads I believe. You could check them out.
So, I don't know if this would fit, but I feel like Battle Tanker's head may work in this case. Now I just need a Prime to test it on.
You mean the replacement head for RTS Optimus Prime that came with the battle tanker set? That head is pretty tiny for CW Optimus...
