Ivo, the tail is made up of steel tubes and bamboo rods then covered with linen, the edges appear to be thick because there is frame right along the edge so the fabric can be wrapped around it.
Bob, the wings are made from two layers of 0.25mm styrene sheet cut to shape and glued together, the leading edge curve is done by wrapping it around a length of brass rod, once the glue is dry the wing retains its shape. The ribs on top of the wing are done with 1.0mm half round styrene strips while the bottom ribs are 1.0mm rond styrene strips. The simulated leather reinforcing patches are painted on using Humbrol No.62 Leather.
