I think they do fly like mini versions of the real thing, [fully fueled and bombed up]. In 1/12 scale WWII combat, 5-10% increases are allowed for the flying surfaces and those planes are good performers, still looking like the real McCoy.

I fly just 3 miles south from where Paul Allen has his P-51, P-47 and Spitfire hangared. Where I fly is directly below where those planes go into their landing patterns and their low speed performance appears to be rock solid. The pilot goofs around if there is a steady head wind, he'll slow way down and see how high he can bring up the nose before stalling. None of those planes have jump seats, or else I would probably be several hundred dollars poorer by now.
