I never thought I'd be able to do this pose with my MP-9B Black Rodimus!! Until now!!
So happy that I got these new diecast metal chrome plated knee joints from Robotkingdom, made by X2 Toys. Beautiful replacements for the very fragile plastic aqua joints on the original figure. So good that there is absolutely no risk of damage when articulating the joint, and that the joint fits in perfectly with the overall aesthetic of the figure, like it was always meant to have chrome knees!
Video of the process I went through to change it, and a closer look at the joint and the reassembly, is uploading now. Stay tuned
