I've invented my own dare.
I will make the complete collection of aircraft of the United States, from Curtiss P-1 up to F-111 Aardvark (lol)
North American P-82!
And what's more, it should have a controllable cockpit! Muahahahahhaha!
Actually this would be my 1,000 point (soon) collection of builds, than to refine my Heizou or Fischl and paint it in silber.
Dornier Seastar
@FreighterCargo Does not exist.
P-82 (Twin Mustang) and P-78 (P-51B) exists.
P-74 Super Mustang
Curtisses XP-18 and XP-19 and P-74 don't exist, neither their blueprints, so to compensate for this I will add:
Bell XF-83
Republic F-84
McDonnell XF-85
