I must be missing something.........

[Knarley-Bob]

On Multiplayer, while flying either a P-47 or a P-51 I'll fly for a while and the engine just stops.

On the P-47 I'll run the louvers on the cowl and oil radiator, keeping everything in the "Green". The fuel gauge tells me that I still have plenty of fuel.

On the P-51, I let the "Auto" selection for that duty, but after quite a while it's engine just quits too. Again. gauge says fuel fine. Last flight, no diving, no combat, cruised at 52% throttle for flight, except at take off.

 

Is there something I need to be doing that I'm not?

 

Thanks,

What RPM are you running?

[354thFG_Drewm3i-VR]

You have discovered the engine timer "feature." 

[Knarley-Bob]

So you can't run the engine at 1/2 throttle?

 

That's interesting.....

 

What RPM would you suggest?

You can.  What is your RPM at?

That I couldn't tell you..........

I fly the same on SP as I do multiplayer.......is that the difference?

The only difference is difficulty settings between SP and MP.

 

You really should look at the information tab for each plane. RPM and MP have settings for most planes that can be run at continuous, 30 minute, 15 minute, 5 minute or 1 minute. Not all planes have the same amount of time for various settings, so best to look at the information for each plane.

 

One of the worst things about the old IL-2 was it got so many people to just look at %s for throttle and/or RPM, and totally ignore the gauges.

[Knarley-Bob]

That's the crux of the matter, I do watch the gauges. There seems to be a difference between MP and SP for the P-47 28 but is only about 500 RPM.

I don't know if one should run on "Auto" lean or rich or what. I run my prop @ 100% during flight.

In the P-47, 52% throttle is about 2000 RPM which should be fine, maybe not I don't know. Is the info for each plane on the game, or do I have to do some research?

[FuriousMeow]

Throttle controls manifold pressure, there's a separate control for RPM/prop. If you are running "prop@100%" that's the 2700 RPM which will blow the engine eventually. Safe continuous is 2550. If you are just adjusting throttle, you are only adjusting manifold pressure. You can reduce throttle and RPM will reduce but it will climb back up. They should be controlled separately.

 

If its working differently between SP and MP, maybe simplified engine is on or some other gameplay/difficulty setting in SP that allows throttle to control MAP and RPM. That'd be the only difference between SP and MP.

like others said its probably engine timer that doomed you, and only thing differant betwen sp and mp is realisam settings that are used, mabe in sp you have some more relaxed things turned on that are not on on server you tryed.

I found Manifold Pressure to be critical in the Yankee birds.

Keep an eye on it, and note that it can increase quickly if you go into a dive.

Don't go full throttle for take-off either.

Once I learned all that I stopped breaking engines 'unexpectedly'.

 

Drop your revs a bit when not in combat, cruise at auto-lean mix and fight with auto-rich.

Full rich is only required for engine start, as far as I understand..

 

S!

So what would be a "Rule of thumb" setting for the prop pitch? I'd like to know about where to start.

For the 47.

Cruise at 42" and 2550RPM.

Combat at 52" and maximum RPM.

Boost five minutes when you need (it will also cool the oil temperature).

Link turbo to throttle and forget about it.

 

Mixture auto-rich always, unless you need to lean to save fuel.

 

Cowl flaps generally fully closed, or 5-10% open if you need a bit of cooling.

Oil and intercooler leave at 50%, occasionally close both depending on external temperature (winter).

 

Go fast, don't go slow.

Enjoy death.

Start a quick mission, go to the briefing map(press "O") and bring up the Specs tab. A lot of good info their, to include engine settings.

This will definitely blow your engine. The propellor control lever is your RPM control on both the P-51 and P-47. It has a governor that keeps the RPM at a speed you select with the control lever.

 

Do yourself a favor and fly with technochat off. This will force you to use your instruments. Pretty quickly you will start to develop a good cross check. Manifold - RPM - Coolant - Oil - repeat.

 

Good luck. You'll get there ?

Firstly, you are not directly changing prop pitch. The governor on the propeller control does this automatically for you. You select the desired RPM and the governor will change the pitch as necessary to get the desired RPM.

 

In terms of a 'rule of thumb' it depends on your flight profile I guess. I tend to use cruise settings the most... be nice to your engine, it helps keep the pilot cool. Watch how much he sweats when it stops ?

 

I will push things into combat power if I have a contact. And through the gate, balls out if that contact is on my 6 and shooting at me. But I'll always be conscious of getting the power settings back to cruise as soon as possible.

 

You can still attain a good airspeed with cruise settings. Once your trimmed out, you'll be ticking along quite nicely.

[Knarley-Bob]

Cutting back on the prop pitch did the trick!!

 

Thank you, guys.........
