Much better experience than earlier. Must have caught it in a bad state in the mission or something. I think I'll stick to the hurricane for now, trying to get my head around prop-pitch means hearing lots of different things from different people.

Rotol Hurricane (don't bother with DH prop it isn't modelled properly)
General guide (my 2p):-
After takeoff reduce to 2600rpm or less, boost 3-4lbs continuous.
You can fly on max boost for a while at 2600 (historically 30 mins max but I wouldn't risk it that long in CoD). Watch the temps (max 95 oil, 120 Rad)

Overheating Oil? Reduce to 2200 rpm and cut back to 4lbs or less - soon cools down*.

Combat: Have cool engine (about 80 oil, <100 rad) when entering combat. See above*.
Combat 2600/max boost - combats don't usually last long enough to damage engine - and max rpm/max boost when necesary but 5 mins max (watch temps). Also don't forget Boost Overide for the extra bit of power but not for more than about 5 mins. Cut back on boost/override whenever possible.

Continuous max boost or Boost Override can also fail the engine without temperature warning.

Thanks! Just to clarify- I move the prop pitch lever rather than the throttle to adjust rpm?

Mixture should remain the same generally?

Edit: Just went up for a flight (cross country quick mission), that worked great, thanks! The other hurricane is a bit easier to keep the RPM at a nice level and the engine shakes a lot less (only on start up now, rather than in flight).

With this hurricane, mixture is full back = rich? When would I use it pushed forwards, other than a little bit at takeoff- at high altitudes where air is thinner so less fuel is needed?

Yes you move the Prop lever to control the prop rpm but at low boost it will fall away anyway.

Leave Mixture on Rich (lever back). It could be leaned (lever forward) for economic cruising wih restrictions on boost/rpm but lets face it, you're not going to be doing that unless you enter into a 2.5 hour patrol scenario By the way if you fly the Spitfire as modelled at the moment the lever is the wrong way round - forward is rich. Should be fixed sometime.

You can play with the mixture, leaning it gradually until the yellow exhaust flame just turns blue but then you are on the edge for those particular circumstances (boost etc) so I don't bother. We're never up long enough to run out of fuel and we can keep the engines reasonably cool by boost and rpm. Focus more on basic tactics like being above the bandit rather than below him and get out before you lose the advantage - ahem.... do as I say not as I do!

I'm only trying to give an operating guide, I'm not trying to give you the perfect setup for various conditions. You could research those in the Pilots Notes and see if the modelling is perfect or not but frankly those are test scenarios. Some guys worry about things like "the flight model delivers 8mph below the XXXXX test data". Well, all a/c were different anyway with no guarantee of returning that test performance and its unlikley you'll be in a perfect "test" situation when you spot that bandit. And as a newbie to the Squadron do you think they'll give you the factory fresh aeroplane? No, the boss gets that one, yours is the one with the near-expired engine

in fact on many occasion that was just the opposite.

@cheese, I use lower RPM than most, usually plodding about on 2000. It's all tactical anyway, just plain don't need that top speed because I catch Hun in the right place. If you are going flat out they've already seen you.

Just kidding him, the point is that we all hang our hats on the perfect 'test performance' aircraft but in RL there were variations between aircraft depending on hours flown, past damage etc.

+1 over than speed I stay away from the FM talk, there are just too many variables and "experts" to ever make me want to openly discuss them.

The way I see it is regardless of what you fly its down to who sees who first.

Just wish I could follow my own advice and not plough head long into a fight regardless of who has the advantage

Hi klem, what do you (except reverse mixture lever axis) consider as a problem with the DH? In my opinion it's not too bad and the RPMs are as expected - once in the air mind you

All great but wasn't the 30' climb limit at 2850rpm @ +6.25PSI? This works both in RL and in game. Great guide btw.

If you set the boost cut-off on it will cool your engine.

Try to use it only when you are on the defensive. It's kinda a cheat.

I expect this to be corrected in the same time they re-installed the more stringent 109's EM rules.

280 is what you shld get with a hurri. Start with a shallow dive and coarse the pitch at 12hr (needle full vertical). Retract your rad to 1/4 to 1/3

With a bit of descent rate you shld get 290 easily. Th's a lot deck even if the 109 will still catch you, you'd get time to think how you can manage the unavoidable fight.

The few time I hve tried the Spit I online I did not have any prob keeping a 109 in gun range. But it might hve changed with patches. I am not the best to make a comment here

In my experience it's quite the opposite - more heat and more strain with the BCC-O (even though the MFP gain is tiny atm). Can anyone confirm?
