It is without a doubt, let no one tell you differently. There is no possible way for anyone to have the firepower, speed, climb, or turn ability (etc) in a P40x that would lend him the same capability as any of the F4U's to get done what he just said he likes to do (engage a horde). Is it absolute? No. But the odds of *anyone* engaging in the MA's or a duel while in a P40C vs the typical LW fighters are strongly against them. Having a P40C handicaps their ability in a major way. If it wasn't the case then the numbers would be much more balanced across the board in terms of plane usage. The F4U's can have outstanding boom-n-zoom abilities, are fast, retain E very well, have average or better firepower, and if by chance the P51, La7, or Dora gets on their six with equal E the F4U is one of the few planes that can run almost as fast and yet outmaneuver them at all speeds.
The argument of "it is the pilot, not the plane" is an incomplete statement.
Again, this wasn't in question (from what I've seen).
The question appeared to be about respect earned as it related to landing kills in different planes.
I'm anxious to hear what mtnman has to say about the P40C vs F4Ux in the MA or in a duel.
There-in lies the error in your thinking...
Do you assume that landing kills in the P40C means the pilot killed an F4U? Or fought alone (i.e 1vs 1)? Or did anything but linger on the outskirts of a fight to jump in and pick planes that were defenseless for one reason or another?
I would argue til the cows come home that I could fly a P40C and make/land kills easier than I can in an F4U-4, simply by flying in different areas, and/or under different circumstances than I fly an F4U-4. I've done just that in a P40 (but I don't think I've ever flown the P40C?).
For example, I lone-wolf fight against the hordes in an F4U-4. That's difficult.
In a P40C I could fly with a squad protecting me, and only fight "safe" opponents. I could gang, instead of fighting the gang. That would be easy in comparison to lone-wolfing against a horde in my F4U-4.
Landing kills in my P40C, if you thought I deserved respect for being successful in the "difficult" plane, you'd be mistaken. If you felt I didn't deserve respect for landing kills in my F4U-4 you'd be mistaken.
Heck, I've even easily beat multiple opponents in a P40, simply because they were very unskilled. I landed their scalps, and was saluted. I've done that on multiple occasions. If someone (anyone) thought it was a noteworthy accomplishment they were wrong.
You cannot accurately judge "respect" earned based on kills landed in plane type.
