Prop Pitch question...

[na85]

Okay, I would very much appreciate if someone can clear up some of my questions:

If I'm in an American plane (p47, p51) and I want good level acceleration, should I be at about 80% pitch or so or should I do 100%?

If I'm in the same plane and in a hurry to get somewhere, or to get away from someone, should I be at 100% pitch, 110% throttle? Or should I be at lower pitch?

Does the same thing apply for Russian planes and FW190's (in manual mode)? (I'm aware the 109 has a different manual pitch system)

Thanks
