Guys, regarding the He-111, I just took it up for the first time and I had quite a fight with it!

I left the oil rads closed for much of the warm-up, but still the temps didn't want to go much over forty... - Bit surprising that, but well, they crept up to a balmy 80 degrees during flight, so I guess that was ok.

On take-off I had to close down the port engine almost fully, to keep the plane from exiting the runway to starboard. Well, I solved that too, and got into the air.

however, when up and flying the trouble really started! - I could hardly get the old bird to go more than 200 kmph. Also, rpms didn't go much higher than 1700. I had superchagers "on" for the whole flight, am I supposed to have that? (The old version with just on and off settings)

I also felt it was really difficult to trim out the plane... - Anyway, lots of trouble and not a very successful flight. couldn't keep up with the other bombers...

Any pointers to how I can get it up to around 350kmph?
