Nerfed flight models or control surface range limitations?

[teambayern]

How big are the problems here? I've always wanted to get into flight sims (got pretty deep into Falcon before my computer died) and was hoping to finally make the plunge now that a real sim has come to the xbox. I'm reading up on things like propwash, adverse yaw, ect. and it seems like that's all there. But next I'm reading up on the specific planes and their advantages and disadvantages. Is it even worth it? Are we talking about minor inconsistencies or serious problems?
