Spitfire prop pitch and radiator question

[stugumby]

Greetings, im curious as to at what mark for the spitfire series do we loose the ability to manually adjust prop pitch and radiator settings. I have noticed in my 4.11 with hotfix unmodded install that i cant adjust pitch or radiator from mk8 onwards. In the small tail mk9 from late 42 and 43 online i asked on chat and was told to set a key, i have increase and decrease prop pitch set to my #11 and 12 on my logitech x3d and it works on all others i have tried. Is it a peculiar thing just with the mk8 and up? I was also unable to manually set radiator settings. I am also understanding that supercharger in these later model spits was alitude operated without pilot input so thats why i cant set those as well. Am i on the right track with my key settings as ive got # 9-10 as supercharger and #7-8 as fuel mix settings?
