I've been practicing one-on-one vs 190s and I've been slowly getting better. My opponent is on "high" skill level and I can generally stay behind him, get some hits on him, and keep the fight going until he runs out of fuel and bails. But I find it very hard to get a good bead on him as he's always just a little bit out of reach.

 

I was just wondering what others have their engine/prop/flaps settings at? I usually keep prop at 2700-2800 rpm, MP at 45-50, and I don't like to use flaps too much unless I'm in danger of stalling. Oh, and I have oil radiator cooling full open which I find helps a lot.

 

Altitude is under 8,000 ft.

 

Any expert advice?

3K RPM, 61" MP, flaps 0.
Thanks. I've tried 3000 RPM and 61 " MP but I find the oil temperature shoots up in no time and the engine starts knocking. I know the engine is supposed to be good for 15 minutes at those settings but I just seem to run into problems in less than 5 minutes.

 

Maybe if I flew at higher altitudes?

as long as you keep up your speed you should be fine....btw, anything above 46" mp should be run with 3000rpm and not lower!
ok. what speed should I generally try to stay above? By the way, I'm in the middle of RTFM but not done RTFM.:)

well, hard to say, as at least I dont have any specific number...but for sure i would avoid getting slower than 200mph.if you still do, then watch your temp gauges(you should do that regardless of speed on a regular basis anyway).if they are reaching unhealthy levels, then throttle back, or lower the nose to regain some speed again, or do both...(also you dont want to have your temps too low as this can just as quickly kill your enginge)

 

EDIT: also, this is only a general idea, and if i were you, i wouldnt stick strictly to any certain numbers in regards of speed, at least as you ask for settings during fights...if you think you can pull lead on a bandid, even if it means pulling hard at stall speed, then do it!

good thing is, your licence is not running out after you have killed x amount of engines/planes :)

experiment, and with time you will feel how far you can push her.

You should maintain WEP with 3000RPM when in combat. The P-51 can WEP indefinitely so long as there is sufficient airflow to keep the engine cool. Make sure you check both temp gauges during combat. COOLANT TEMP is the critical one. It almost always will be the first to overheat, and if you keep the temp below the redline, the chances of a engine failure are extremely slim. Basically, keep your Power at wep during the fight and constantly check that temp guage, if it starts to go red, you should throttle back until it goes back down, you can then usually throttle right back up to WEP so long as you gain some speed. In a emergency, you can operate over the red line for short durations, depending on how long you were at full power before hand. This is why it is smart to run mil or cruise before fights, so that you can push the engine hard once you do engage. I cannot emphasize enough though that I run WEP nearly the entire time I am in combat and I almost never ever have a engine failure.

Oh the manual is wrong about only having 5 min under WEP?

It's probably like that in real life but maybe the wear on the engine from WEP just isn't 100% modeled in the sim.

5 minutes is a limit that has more to do with overall engine longevity than actual in-flight failure. WEP power testing to determine highest sustainable power usually lasted for hours not minutes. The risk is that if you run WEP constantly you have to keep a close eye on the temps, as you are running the engine very hard and the cooling system and other components are being operated on the edge of "safe" operation. You are also wearing the engine out faster in terms of its total life span. Take for example your car. If you ran your car all the time at MAX RPM/THROTTLE etc, you will most likely not suffer some immediate engine failure. However, if you run like this all the time, instead of driving like a normal person, you will reduce engine lifetime. Overclocking CPU's can have a similar effect. If you overclock within the thermal limits of the chip, you probabaly wont kill it out right or even within several years, but it probabaly wont last as long as a non-overclocked card.

In short, if you ran the WEP for longer than 5min, a noticable reduction in engine life would occur. This means the engine on your mustang would have to be replaced more often between missions. This is also the reason restored warbirds today are not run at anything near full power to conserve engine life. Pilots in ww2 ran whatever power setting they needed for as long as they needed it to get out of trouble. It is true however that planes using MW50 and P-51s at 75inches had much shorter engine lives, in the area of 2-3 missions vs 5-10.

It also wouldnt be very relevant in the scope of DCS in most cases. The loss of HP from wear in the space of a DCS mission would be negligible. Now if we had some kind of dynamic campaign, and you kept going on 4-6 hour missions where you ran WEP for more than 5min each mission, you could expect to see that engine die withing a few missions. I think a feature like that would be very interesting, as then spare engines could be a airfield resource just like ordnance is now.
