The fuselage is basically a balsa box with triangle stock glued on inside corners. From outside is simply sanded to oval cross section shape.
It is not so hard to shave all materials from outer corners as it seems at start. We start first with rough planing the corners, and later we use sandpaper on the wooden plate, and later we use fine graded sandpaper with "bare" hands, to feel the shape. We dont use much measurements or templates here...we just finish with sanding, when fuselage starts to look good!
Basic fuselage parts...cockpit parts!
Bottom of the fuselage is laminated from 4 strips of 2mm balsa in template made from styrofoam.
