Patch 4.11 is a gift to open pit UFO fliers

[swiss]

Maybe this problem is connected to the new proppitch in 4.11?
If I understand it correctly, high power means low pitch, low power high pitch.
Now, if u dive with auto pp, you will run the engine with too high rpm, which leads to "premature" overheating.

Just a guess, havent tried, I also always flew with manual proppitch before - and only used low pitch in a dive with low power to slow down.
