Why do I have to fibre-tape the wing saddle?
Gluing EPP foam to it’s self is NOT a good idea in small contact area/high stress areas. This is because EPP foam will tear in shear alongside of the glue line. Gluing taped surfaces together distributes the localised stress over a greater area, i.e. up the sides of the fuse and out over the surface of the wing root area. Same goes for the tailplane saddle. If you cover the wing (and/or tail) in a heat shrink film (such as Profilm} or coloured PP tape, it should be cut away in the saddle area.
