radiators have no influence on speed

Should they have an impact on speed?

Keeping your 109 cool sounds good to me and without a performance hit is even better.

I think there busy trying to make the “game” playable.

Key word here is “assume”

Fact? Please quote your aeronautical engineering data.

Key word here is “game” but maybe it’s more of a “sim” than we think. The P51 Mustang’s radiator has a low/no drag design.

“The duct for the radiator was designed to slow the incoming air down. The air could then absorb more heat from the radiator, but the radiator needed to be made larger because of the slower air velocity, which meant installation in the rear fuselage. After the air passed through the radiator, it expanded due to the heat and was accelerated out the back, producing some thrust to counter the drag the radiator caused.”

I don't have the time or energy to do the research the 109’s cooling but here’s some cool (pun intended) data about the pesky little 109 I did find. Instead of beating up the devs … research it and present the data to the devs.
