I collect a stack of Lego and a stack of Transformers, so this was a really interesting experience seeing this all come together. I still can't believe this thing exists!
What was also interesting for me was this was the first time I've modded a Lego set while in the middle of putting it together - I was just really keen to see if I could get some workable knees in there!
I agree with Lego's choice to not include knees by default though, as he's a chunky boy and being Lego it's a bit of a thing when he topples over on the shelf. Here's some WIP shots that show the little stabilising piece I put in the back of the knee so that it can lock in to place when not bending. The ratchet joint is plenty strong enough, and still allows for rotation when straight.
