But in regards to the blacking out, there was a P-47/Fw-190 test posted here several times, and it mentioned the Fw pilot kept blacking out or graying out in the high G turns. So, yes, there is mention at least in one test of 190 pilots blacking out.
As far as the "conspiracy" talk, I don't think the LW fans really believe there is one, but..........from the perspective of others, when you look in the "Aircraft/Vehicles" forum and see thread after thread after thread with LW planes in the title, and you read them and see nothing but complaints or "notes" on how those planes "should be" as compared to AH, well, you do tend to develop an attitude about the thread author and yes, sometimes it does appear that they are alleging that HTC purposely models the LW planes' performance deficiently.
Are all the planes in AH modelled correctly? Who knows? I wasn't even born yet when the planes in here were built and flying combat. I suspect that neither were 95% of the players in the game.
Do Allied planes fans complain? Sure they do. Are they as voracious and aggressive with their complaints as the LW types? In my opinion, no.
From what I have seen, whenever a LW plane complaint thread starts, it starts out civil, then if HTC doesn't respond instantly, the author or another LW fan starts in with sarcastic comments, i.e. "it does no good to post this, they won't listen anyway." Then within a couple hours, we get the replies from other LW fans with "

" smilies in them, and from there it generally progresses into a flame war.
HiTech himself commented on the topic about LW threads some time back. Search it out, read it, get it straight from him. That thread tells a lot about how he regards a thread just from the syntax and wording from the players.
Simply put, if ya got a complaint, and don't want a flame war, email HTC directly. You may not get a reply, but you will have handled your complaint in a more mature manner than airing it out here and starting yet another flamefest.
BTW, if you reread the whole thread, you will see that ammo was NOT the first to mention "conspiracy". Squire did that in the reply above ammo's. Maybe you owe ammo an apology for your lengthy diatribe and should address your comments to Squire instead?
