I've been playing the British campaign and for the later part you play mostly with the type Ia Spitfire.
What I've noticed is that the plane is really slow.
So, I read about the AI engine management problem and thought “hmmm great don't want to really fiddle with this every second”, but on further investigation, it seems that there are only 3 different settings required:
Low -slow (Rich mixture and fine prop setting, mostly take off speeds)
Low - fast (Rich mixture and coarse prop setting, from vid at about 120 mph)
High - fast/slow (should be coarse prop fast or slow due to thinness of the air and lean mixture ... doesn't really matter since most combat in the game is at low altitude)
In the vid it shows the plane kicking into higher gear at 200 mph with the optimum rpm speed for the later model automatic prop pitching optimized at 3000rpm... which would be my target as well.
So here is the problem... The engine never spins past 3000 rpm on the fine pitch. Even whilst going at 300 mph, if I switch to a coarse pitch, the rpm's instantly drops to 2200 rpm and starts detonating and a huge bleed of airspeed. I’ve dived straight down from 18000 ft with the coarse setting with full trottle and the rpm's never reached 3000. I'm running patch 1.4072. As a result, I obtain a max straight line speed of 320 mph in the Spitfire Ia with the fine prop pitch. (between 0 and 5000 ft) . I quickly checked the manual now, and it seems that this is the correct-ish speed ) (between 450 km ~ 550 km) for the Spitfire at this height, so it seems to me that CEM is just incorrect. (Question markI’ve quickly played with the Me 109 as well and find that the max prop pitch increase of only 10% is viable before the engine starts detonation.
I thought maybe that since I had radiator management on AI that the rpm’s are kept down to prevent overheating, but this is not the case after checking.
Any comments or suggestions anyone?
