This is a continuation from my previous thread about using styrene for knees. I'm about to build the knee joints for my 1/24 scale project. When I made the prototype legs, I used a double knee joint in an attempt at squeezing out the maximum posability. However, i'm starting to wonder if that's actually necessary, and perhaps a single leg joint would work better, and be more stable. A single joint will give me around 80 degrees of bend, can't imagine needing any more. Can anybody suggest a reason to go for double jointed knees?
