Interesting. So what USAAF called "max cruise" is what Luftwaffe called (translated) "fuel save," and what USAAF called "max continuous" was what Luftwaffe called "cruise flight"? Or ... what?

For USAAF fighters, there were four given ratings. In order of most to least fuel-efficient, they were: max cruise, max continuous, military power, and war emergency power. In English aviation terminology, "cruise flight" means "fuel-saving flight." Max continuous referred not to fuel efficiency, but rather engine temperature.

[edit: derp! Most to least, not least to most.]

In order of most to least fuel efficient:

Sparflug = max cruise
Höchstzulässige Dauerleistung = max continuous
Steig- und Kampfleistung = military power
Start- und Notleistung = WEP (without MW50)
Sondernotleistung = WEP (with MW50)

Reiseflug is somewhere between Sparflug and Höchstzulässige Dauerleistung.

For the K-4 Reiseflug is 645 kph (1030 PS) at 8,4 km altitude. Dont know what ata it corrosponds to and 645 kph seem a bit fast for 1030 PS, but this is theoretically what it should be trimmed for!

Ok, just tested. Thats 1.15 ata at 2400 rpm. The rudder is perfectly trimmed at that speed, buuuuut the elevator is totally out of whack! The nose points to the sky.

But the engine settings seem to be correct. Please try 1.15 ata, auto pitch sets 2400 rpm by itself btw. But the plane is not trimmed!

Can someone explain why the Germans thought a plane didn't need a pilot trim?

Trimming the rudder and ailerons helps the pilots on long flights and not so much in dogfights. Ask yourself how many times did you trim the rudder and the ailerons in combat?

I trim before getting into combat. Everytime. There's more to flying than just the dogfight. Plus, it makes aiming easier when the plane is trimmed.

Probably because Germany had to do with very limited resources, and aileron/rudder trim was considered a "nice to have".
And in fact this limitation did not prevent the German "Experten" from achieving astronomical kill counts.

Yes, when the pickings were easier. Plus, the pilots flew forever.

The german planes were trimmed on the ground for a specific ATA and rpm.
