These were inspired from a couple of simpler models, but really nice, designed by Mauther, from Papermau, an excellent site I highly recommend visiting often. This is where I am with them. I just don't know if anyone would be interested . It doesn't fly in space, and it is mostly out of my head, inspired by Mauther . They have a way to go, but the bodies easily unfold, as does every part on them.
