Figured Id post this up since theres so little mods. Just need an RID Seeker, a screwdriver and an exacto knife. Even has a place to store the head in vehicle mode!
I have him but hes at work wont be able to try it until Monday. Would probably work well, even my extra sinnertwin head works well with the mold'
I've been thinking of trying a Titanmaster on Robotmasters Optimus Primal. If it works I'm going to but Titanmaster Apeface. It already worked with Armada/Transmetal Rhinox.
