@ Paúl - the kit is work-intensive but I am enjoying the build
Almost the entire wing leading and trailing edges have movable surfaces, which are modeled separately. Thus, the main wing skin parts only cover a fraction of the surface.
The leading edge, particularly near the wing tip, has a very small curvature radius. It is tricky to achieve and half cutting to model the angle just below the leading edge is not a good idea because the paper would delaminate in the curved section. The slats can be assembled in the extended position and that’s what I intend to do.
