As you asked...
I just love the large scale airplanes, and Airfix was the first (at least to me in my younger days few decades ago) that triggered this love - a superlarge Ju 87 Stuka in my local shop, impressively waiting at the top shelf - with an even more impressive price tag on it (beyond reach for an eight year old boy).
But it kept me yearning; in the meantime I bought several... and most of the other ones as well.
Yet, there might be some other planes looking fantastic at great scale:
I am crazy for a 1/24 Me 262 in whatever version, as the RAF now has a significant advantage here with the Typhoon and the Mosquito; another very interestiing thing would be a Boulton Paul Defiant in 1/24 (not really an Axis force plane, but a beauty anyway.
The Westland Lysander would also be a hefty piece of art (or work, I suppose). And the Vought F-4 U Corsair, the Hellcat would be great, a Wildcat, too- and so on and so forth - you asked!
I am well aware of the costs for making the tools for a single one of these planes, and I am pretty sure that none of them will show up in the next couple of years or so - but it would be really, REALLY nice, you know?
And with these little motors for the props they do even better... so do not forget the motors. Please!
