Lance, Stephen, Rick, Marc, Frank, xmald, Xan and Giuseppe, thank you very much for your kind words!
I painted the interior of the side panels and the forward fuselage cover. On the edges I had to remove some material to make the panels fit the fuselage frame:
Meanwhile I closed the fuselage. I used Vallejo putty for the first time to close some minor seams and it works really fine with a watered fingertip.
I also glued together some subassemblies. I dryfitted the fuselage and the engine cover. The fit is very good.
Best regards
Andreas
