which one u fly? there are huge differences between the various versions u can find in CFS3: but I guess the one u are referring to are the ETO versions with avhistory flight models built in.
if so, u can be sure they are really good! only tipp is to fly this ship carefully and keep on flying. like the real ones they need a lot of training but one principle is clear: never try to bank, let alon hard banking, if u are not doing 400 kph at least! in the web u can find pretty good stuff: ( I mean manuals) that´s the nicest part of flying warbirds!
