I reverse-modeled the fuselage based on the internal framework.
I then manufactured this using an FDM printer, which I call the "printed inner shell." Compared to gluing cardboard, this saved approximately 7 days of work. It's also more robust, provides stronger support for the skin, and is less prone to bamboo jointing issues. Setting aside traditional preconceptions, FDM printing technology complements paper modeling to a remarkable degree—it's truly a match made in heaven.
Instead of fabricating inner lining pads for the intake, I directly applied metallic paint to the backside. Cutting away the black lines caused the skin to fit somewhat poorly. Overall, the longitudinal length has been shortened, and the first few sections became too short transversely. But in short, the more coherent skin effect is worth it. Although I employed very aggressive techniques, the actual construction process was no different from traditional framing. The skin is still glued together first before being fitted over the frame, rather than being directly attached to the printed surfaces.
The rivets were rearranged according to the reference photos. Laser-engraved rivets with a diameter of 0.3mm and slotted screws with a diameter of 0.5mm.
The exterior was dry-brushed with Tamiya Aluminum, followed by painting scorch marks.
The interior was painted with gunmetal.
