I have another question regarding the XP-72, how is it possible that she was much faster than the P-47D at altitude?
If you compare the numbers you will see what i'm talking about....
XP-72

normal weight: 14.760 lbs
power available @ 25.000ft: 2400 BHP @ 2700 RPM...

All those measurements to balance the elevator forces (hingeline) are common practice at this era. But i still have doubts, because aircraft of compareable size and weight need to have balance tabs or springforced tabs additionally. And a lot even smaller(P-61, F4U) used this kind of "power aid"...
