Me110 and He111 if not others engines failing soon after join flight

[BOBC]

Hi,
4.312 Blitz
I didnt have this happening last time I flew test flight. 2 months or so ago.
Why is this happening when I havent made any changes ?
I am in full mission builder, I open my test flight mission 110c, and rattling sounds flames from exhausts etc 30 secs or so after the sim starts (I am already in air by the way, I start in air)

same for He111,

109 didnt do it though.

I dont want to be fiddling about with engine controls, I am skinning not gaming as such with this flight, so what is happening and why this flight and not previous, I have not altered anything.
What settings to let me not have to bother about controlling engine as I have never had to do so so far. I want engine management rad management etc auto ! or newbie mode etc.

69th_Zeb had said hit D P for decrease prop pitch else engines will burn up, 110 was about 10to 2 so I tried that until at 12oclock but I have even more flame and earlier demise.

I dont see how I can be having this when I dont ever alter engine settings, just fly and test colours etc, what has changed ?

Cheers
