It does not matter how long you've been playing IL2
I've been flying for more than 10 years and it's not a little, will not you agree?
But this does not apply to our question.
In the last patches appeared the problem, about which I wrote earlier.
At all BF 109 (without MW50) flaps in auto mode work correctly, and on BF 109 with MW50 – not correct.
P.S. Regarding the temperature indicators in BF 109 K4:
Upper - Temperaturanzeiger für Kuhlstoff - water temperature
Under - Temperaturanzeiger für Schmierstoff - Oil temperature
Learn the manual Kameraden)))
