Hi Ton,
purchased a kit second hand. The instruction is very short and numbering of parts is missing in the fuselage construction overview. Nevertheless I managed to assemble the fuselage and built in right thrust.
The only part I am missing in the plan now is the fuselage front top planking, on formers F2A, F3A and F4A (two parts. The 3mm balsa ring does not match exactly, needs to be shaped to fuselage tapering from cowl to cockpit section.
From your pictures this section seems to be very flat. Will refer to the sections of the formers on the plan.
Greets, Franz
