Hi Ditto,
It's mainly in the damage profiles i find, also the take off & landing characteristics,you need to set flaps accurately,and it'll yaw like a S.O.B. if you open the throttle too harshly, bouncing down the runway like a kangeroo if you get it wrong landing, is fun too !
In damage profiles wont take many critical hits to have you in an uncontrollable spin & when you Stall YOU STALL !!!
My favourite is Phillipe Burnargge's Mosquito FBVI, one hunky machine to fly! one of these day's i'll be able too

AND !
Forgot that the AI's can ALWAYS out turn you, & it a job to get them off your six...
The weapons also will be a calibre of the correct period.
Fly it in VC mode as well (virtual cockpit)that'll sort you out
