Hello Somerled, and welcome!
There's no "sticky" or FAQ because there's SO MUCH information about what's going on in and around the game, that the FAQ itself would require it's own webpage, and amazingly enough, it DOES.
That's part of the problem. There's so much information out there, that even 10 years later, we're STILL learning about certain functions of the game, the aircraft, and the tweaks and guidelines of how to do things. Unfortunately, there's no real "quick prep" out there that'll work.
For instance, the two questions you asked 'how do i turn properly without bleeding all my E' and 'whats the best fighter'... technically, neither of them have distinct answers, so they wouldn't be in a "quick bite" type answer. In the case of the best fighter, that's a very subjective thing. Some people think the 190D is phenominal as it can outrun almost anything, has hard hitting guns, and a roll rate to shake even the most maneuverable off your 6... some people prefer the P-38, as it's ability to keep it's nose pointed straight up and STABLE is almost unparalleled. You'll have defenders of almost any fighter craft out there. In terms of "turning properly without bleeding E", that's actually slightly different per aircraft, as each aircraft has it's own speeds it does well at, meaning different amounts of pressure on your controller during different speeds with different aircraft would be the best answer, and that's where websites like the Trainer's and Soda's aircraft Evals come into play.
Welcome aboard to the insanity. =)
