Thanks heaps, Moritz!
I tend to build wheels-down to give me something to stand the builds on. However, I agree with you about how fast she looks.
So, the B-27K I have planned, which I think should look even faster, may get the flaps-up, wheels-up look (depends on how the Hasegawa B-25J behaves).
I'm not sure if I want to do the bomb-bay open or not, depends on whether the Hasegawa kit is up to the standard of the Airfix kit in that regard (Airfix's bomb-bay looks good straight OoB but I, also, have
two Eduard upgrade sets for it (one for the next Airfix B-25C/D I get)).
