P-40 Throttle, RPM control and Prop Pitch control


Recommended Posts

Posted

I just am not sure what the point is in regarding getting the most out of the P-40. It seems to me that except for the most pilots that you might as well leave auto prop pitch on.

I have been moving the RPM control near full and controlling the rest by the throttle.

That's the way it's supposed to be done.

Well the auto prop pitch is there to be used for sure, but you have to keep a sharp eye on the tachometer. The auto mode will often drag you towards 3000rpm which will destroy your engine after a shortish while (I think it's 10 mins? Definately longer than the limit on the 109F4 and 190A3)

 

Using manual prop pitch gives you much better control over when you enter the WEP range, but ofc it also increases the workload a great deal.

The manual RPM (NOT prop pitch) mode was meant to be used only when the auto mode failed.

How do you enable auto rpm? I've been flying it like any other VVS aircraft so far.

You can leave auto pitch at 100 percent. Never any problem for entire flight. Its the manifold pressure that will cook your engine in auto.

That's exactly how the auto rpm work - like on any other VVS aircraft.

Yeah. One shouldnt be bothered with manual RPM. BTW I love this underdog.

True dat. But it has nothing to do with the P-40. I think I'm one of the few who never expected it to be anything but an overweight American with too many guns for his own good ;)

Which unfortunately doesn't happen in BoS. I was really surprised when I suffered damage to the governor (can't remember which plane) in '43 and the RPM would all of the sudden go nuts when diving. Had to throttle back and turn towards home almost immediately.

 

Of course it's rare, but this kind of damage modeling would nice to have in BoS.
