This remember me when, some time ago I was showing a Bf-109 from IL2 1946 to a veteran pilot that flew the Buchón (Spanish built 109's, based on G-6).
He told me that Il2 was unrealistic with flaps (too much quick to operate), so reported that he needed one minute to lower the flaps by actuating the wheel; it used to be slow, hard and sometimes slippy if some oil reached the wheel.
Flaps used to be lowered only prior to landing, in the tailwind leg, using all the entire leg.
Of course I speak about operations in Spain, those 109 and its pilots did not see more air to air combat that the one they trained between them and the one they recorded in the Battle of Britain movie...
