Mine isn't quite full scale, but full scale looks a bit big on a normal person. The scale I have set is a good size for most people, I believe scaled to a 6' 4" person? So just keep it the same scale, and it will work. The way I made the model also makes it so you cant get it unfolded full size. My ar's a bit more detailed than FS's, but FS's is easier to make.
