2 pitch propellers - advice needed

[reflected]

Guys,

I could use some help with 2 pitch propellers. I know that you have to set it to fine for takeoff, and coarse for cruising. I also know that the max RPM for the Merlin is 3,000, and the ideal for cruising is around 2,000-2,100.

But how do you set the prop for climbing and fighting? If I set it to coarse, the plane becomes sluggish, and the boost gauge goes up beyond the red (that makes the engine overheat), on the other hand, if I set it to fine, I have to throttle back otherwise the engine would overrev. I also have the impression that it seriously limits the top speed (duh) so it's not that suitable for combat either.

So, what then? How do you fight, and do you set it to coarse immediately after takeoff?

Thanks in advance!
