OK I think I found the key to my overheating of engines.

Prop pitch (and probably radiator opening)!!!

I just did a QMB flight vs 4 empty HE-111's on the Normandy map flying out of Carentan and although the engine overheated a couple of minutes after take off I was able to cool it by reducing the prop pitch so the RPM's dropped, and I opened the radiators.

I found it difficult to get speed up by doing that though, and I found it difficult to catch up with the HE-111's to intercept them to begin with (not least because I headed in the wrong direction for about 2-3 minutes whilst I sorted out my plane for a reasonable level flight and to gain speed), but for the rest of the flight I managed to achieve a fairly constant 200mph at about 3000ft +/- 100ft with RPM's between 2500 and 2700.

So, I'm guessing I now need to learn what RPM to keep planes at for cruising and climbing/combat. Is there a handy crib sheet with such info (doesn't seem like the included Aircraft Guide for Il2 1946 contains such info)?
