Quoting sietse vd molen
that door system is so cool. how did you put the articulation on the inside?
I got the idea from the LEGO airplane sets and from Mike Yoder who used it in his osprey (thanks Mike). It uses four of those droid arms to hold the door and therefore gives it the articulated motion. I'll post a picture of it here soon, but in the meantime you can take a look at my brickshelf account, user: vman, where I have pictures of the door from the inside.
