Haha, you don't need more than 4 buttons on your stick and $20 for it.
Thats how I did it in WarBirds and I did use rudder and trims fine, like I still do.
"being elitist" - how about playability? I really don't mind to play some fly-by-wire games or face some people flying against me in fly-by-wire planes just because they didn't want to practice flying but wanted to be killers in the very begining as they get engine on.
"trimming all the time is quite annoying", you don't have to trim all the time, just give one good trim and thats it.
"the flight model is "wacky"", I don't have problems with it after I got used to it.
I've flown whole my age with fairly cheap stuff..
In the begining of AH beta I had P133, with 18 fps being maximum and sub-10 more than half the fight, still I didn't do THAT bad.
Which is more annoying, 4 button cheap stick or FPS below 10?
..I still don't have rudder pedals or throttle or.....
Well, of course you can be from playing the game and stick with WarBirds, so we who wants to qualify flying can fly in peace

...more realistic WW2 sim?
well, AH has been slowly being pulled away from the 'realistic' state.
If you wan't to know my answer, WWII online seems good so far and it shouldn't be too long till it comes out.
"gimme a break and stop being elitest."
my answer: quit being a dweeb and learn to fly!
