As for the Mosquito (ish) – I agree, it too has no place in Historic; I cant comment on why it stayed there.
I can only speak for myself in that I didn’t move the ‘Mosquito’ as, although it is not in any way historic, neither is it GA, in the sense of an aircraft your average PPL is likely to be able ever to own or fly
To my mind the Mosquito is a tribute band, the Spit 26 a karaoke.
But I left the Mk26 thread where it was on the strength of the historic images in the slideshow.
There’s no right answer, just opinion.
