Welcome to CFS2..
yes, the flight models for this game's a bit erhh.. well, like one guy said
CFS2 FM = LoL
but not to worry. There's a 3rd party patch for the FM by Wells. His latest version is Ver1.9. Unfortunately, both version 1.8 and 1.9 seem to give some wingman-crashing-at-takeoff problems (during campaign). But u could try ver 1.7. Should be fine. Do a search of "Wells" on this forum.
Some planes u don't get to fly in the campaign cos they had not entered service at the time of the campaign. Like the Corsair, Hellcat etc. But u can easily open the planes .dp files with Notepad and change the line that says "date enetered service" under [MISC DATA] to say 11/1/40 (which is same date for Wildcat). Its not historically correct but what the hell.
Also, if u wanna fly all the AI aircraft, go to Airbuddha's Hangar or CFS2 Online to download the amended .dp files. Replace the originals n u'll b able to fly them all.
