I can't argue here, didn't try P47 or P51 yet, but F4U-1c right now is one of the best planes in game, you can easily beat any Yak and fight on equal terms with La. I don't know, maybe in Arcade it is different, but when in Historical battles we have USA vs USSR map, USA wins in 75% battles, Japan wins in 80-90% cases against USSR, Germany - 50 to 50. I agree that La are OP, as well as Corsairs and I hope these planes will be nerfed, but in general USSR planes are not OP, or we would have different results in HB.
