Frustrated by level bombing. Please HELP!

[Untamo]

S!

Interesting thread, and got many good hints.

One problem still bothers me:
How do you get the course autopilot to fly straight? .. I set the gyro to compass heading, set the course to same and engage autopilot. The plane starts to weave right and left. It goes in the right direction, but keeps banking from side to side in a sidewinder manner. I've tried to force the plane to go straight with the stick and also with minor changes in the AP heading and it works for a while, but then again it starts to bank.

Is there any way to calm it down?

Oh, and another thing:
What loads can the He-111 P2 (or H2, which one is better btw? ) handle well? I tried the 8x250kg load with 60% fuel and I couldn't get past 2km with 1.2 ATA and fine pitch. I kept the speed steady at 200km/h with elevator trim. The climbing just stopped on the 2km line. Too much load I guess

Ok, a third thing:
The R22 autopilot thingie... this should be the "level stabilizer" we had in old IL-2? .. Well it just sends my He-111 to a spiral. What am I doing wrong?
EDIT: Tested it one more time, this time it put me into a 10+ m/s dive. Elev. trim didn't seem to have any effect on it.
