I wonder what the percentage of full scale WW2 would need to be to make a VERY stock build work.. I think 1/2 scale planes could be built that way possibly, as long as all possible weight saving techniques were used.

it would be a thing of beauty to see....

I still get chills being close to a full scale at an air show ! A half scale in the SHED would keep me awake at night thinking of it ! hahahah
