F4U4, I do beleave that not all that many actualy saw combat In WW2, but I may be mistaken, I am going on memory on this one and the cell I stored mt F4U data in is damaged rrom my tenage years:) I also think itis a bit pricy, having included it in a couple CT set up's for Free off CV's in a sudo 1945 plane set, It's apponet was primarly the George. In that set up it was undoubtly faster( most planes are faster than the George any way), but It did not rule the set up by any means. A squadie of mine has fallen in love with it thought and after hearing him rave about how great it is on Voice I have been given cause to think that maybe it is indead worth the coin. He touts it's speed, climb and durabality.
1,435 George's were built( of all types) compared to some of the planes we have in AH thats quiet a lot( Thats aprox 7 times as many C hog's)
Perk Values do change as well, I do beleave the Ta 152's price has come way down and I think the F4U4 was 60 perks when it came out. Also I beleave the C hog has gome from 8 to 10.
Perkage is afik a combanation of rariety and usage/ impact on game play. the later is certainly the case with the C hog, which had such an impact on MA game play that it was perked.
