I,m thinking of redesigning the hatch lip where i can remove it .I,m thinking also velcro to hold it together.The aft section too, with the heat shield as part of the assemble .Also the whole body in 18 inch sections. With slip joints in the spurs and the out side skin holding the whole thing together with screws at the joints.That way it can be broken down so I can get it out of the room I,m building it in.I,m looking at a hardener for the paper too.But it can only be shipped in warm weather.The hardener will turn the paper rock hard and can be dyed to colors like silver ,gray and black.Also I,m thinking of a stand in pvc pipe to hold the whole thing when done.
