Corner blocks all installed, contour shaped to size. The bottom section of the fuselage is complete. Time to flip it over and carry on with
Every longeron must be shaped to its round contour through planning and sanding. A very time consuming job. The radius templates were made on my
The bottom side of the fuselage structure is completed. Apart from a small detail: Every crossing point must still be reinforced with corner blocks. That’s
Wings and fuselage will be glued together during final assembly and cannot be disassembled therafter. The connecting surfaces must be absolutely precise and therefore the
The curved belly shape of the fuselage indicates the projected weapons bay. This leads to some exciting stringer shapes. Again: draw the curve on the
The center fuselage section carries two seriously dimensioned bulkheads. They will be attached to the main wing spars and transfer the wing forces to the
The first 8 bulkheads are in position. The main longerons fit nicely into the slots. Rear bulkheads still to come.
The main longerons are each built from three sections. The rear sections again are split into an upper and a lower beam. Every section must
