I had to apply some future to the wing joints and now its solid. I still dont like messing with them too much because ive always been afraid of clear plastic.
In the beginning it bugged me but ive i began to understand Sentinel is a smaller company, their engineering is pretty good, and their paint is always flawless. Riobot Gurren Lagann is the biggest offender, that one has zero diecast but it is still an impressive figure. Now they at least try to use some in the joints.
