Quoting J Cooper
Super cool! I would appreciate an LDD file a lot!
I've tried to find the ldd file as I'm planning on posting an update in the next few days, but I'm struggling to find it. DOH!!
May be on the other laptop, I'll try again tonight.
edit: I've added the LDD file for the version 3 robot mode only. transformation is fairly simple, the weapon is saved as a separate "group" so it can be detached without dismantling the hand.
