Totally agree with the above two posts.

Yeah Spit Mk.II is really bad with overheating, see there is a thread just about these issues. Same for 100 octane fighters. (that's why people fly the de Havillands more these days you see :D )

There is a difference between the 87 and 100 octane Rotol versions, e.g. the 100 octane can use the boost cut out override and achieve the boost of +12lbs. The overheating issues become more apparent when you try to climb to the altitude.

(and roll down to IvanK's post)

Not to mention that the mixture as it is in 1.08 is a joke :grin::grin:

Completely agree with the OP.

I fly a IIa all the time and in the latest beta patch its gone horrible! my max speed now is only 240MPH which is just way off real life stats..

Also, i keep cooking the engine which never used to happen at all! this is even with a fully open radiator!

maybe i could live with the heating issue, but when my plane cant even catch up a bunch of bombers is where i draw the line:

If anyone is interested here are the real life stats of the IIa:

Also those arguing about 109 vs spitfire, i found a good documentary on the 2:

Watch video 2/2 first, as the YouTube poster has mislabled the order

:O ... I didn't experience this overheating. I flew rad fully open, high and low. I just kept the boost under the little red triangle and rpm under 3000 :) .. I don't know if this is the "full power" you can use or can you go over the limit for so and so much time. But with those settings it flew forever without overheat and the plane was competitive against the 109s.

The red triangle is around +4.5lbs if I recall correctly and it's just as eye candy in the sim. In the real Spitfire, it vas movable via small wheel on the side of the instrument and was usually set on max. continuous boost, which was different for Mk.I and Mk.II yet it's identical in the sim (= incorrect for the Mk.II actually)

You were not flying this bird at rated settings at all (read the thread linked above if you want, especially the part about inconsistencies with overheating) and if you say it was competitive at those cruise settings (what was your RPM exactly?) then you must be a very good pilot. I personally find fighting a well flown 109(s) tough even on full combat power. The guys posting in that particular thread are often long time Spitfire pilots (e.g. SEE or Dutch) and you can see what they're saying. IvanK reported that issue to dhe devs, there is definitely a serious overheating bug introduced in 1.08.

That you're not flying the RAF regulary is actually a good thing for you just used your common sense and found settings that worked for you. (Unlike Spitfire pilots who know what to expect and what settings to use because they're used to that friom day 1 - and now as it has been changed, perhaps it is more difficult to adapt for them), but then you are even worse off with your performance and it's gonna show when you meet any good 109 pilot trust me ;)

WRT RAF Mixture settings there are multiple issues. Here are the bugs, how it should work. Stick with me here its a tad confusing :)

In Ver 1.08 the link between the throttle and the mixture lever in that when the throttle is closed it brings the mixture lever back is now correct this is how it was in both the Hurri and the Spits. IRL this means AUTO RICH.

However the Mixture strength going to the engine is operating in reverse in all Hurris and Spits in CLOD at present.

The Correct setup in real life is:
Mixture lever Back Mixture is AUTO RICH
Mixture Lever Forward Mixture is AUTO LEAN
There were only 2 positions Forward or Back
In Both AUTO RICH or AUTO LEAN compensation for altitude is automatic.
The only real difference between AUTO RICH and AUTO LEAN is each is running a slightly different mixture strength schedule. One suitable for General and all power settings (AUTO RICH) and the other for range/endurance flying at low power settings (AUTO LEAN)

You only really need to run AUTO LEAN if you are really trying to minimise fuel consumption. Anytime you are running AUTO LEAN there are max boost limitations to be adhered to or engine damage will result. (+2.25Lbs Merlin II and III and +4Lbs Merlin XII). Max power and or Boost Cutout operation at 12LBS must have Mixture in AUTO RICH.

VER1.08 IN COD MIXTURE BUGS
MIXTURE LEVER BACK is giving LEAN MIXTURE WRONG
MIXTURE LEVER FORWARD is Giving RICH MIXTURE WRONG
Lever has infinite movement WRONG it should be 2 position only.
MIXTURE LEVER is not working in any AUTO function since passing around 12,000ft you need to select LEAN to get smooth operation. This is WRONG as AUTO RICH should automatically compensate for altitude.

VER1.08 Workarounds
You will get better cooling using RICH MIXTURE .. it helps on the climb in the Spit IIA especially (though its still out of wack). On take off once full throttle is selected push the mixture lever fully forward to the RICH (WRONG POSITION IN VER 1.08 ) Passing around 12,000ft you will start to get rough engine operation so pull the lever back to the LEAN (WRONG POSITION IN VER 1.08 ) If Activating BOOST CUT OUT you must be in RICH so push the lever forward (WRONG POSITION IN VER1.08 )to RICH .... if you don't you will get rough running and engine damage.

HOW IT SHOULD BE USED IRL
In Reality all you really need to do is just leave the Mixture in the rear position in AUTO RICH and forget about it. You then have Automatic Altitude compensation, No BOOST limitation restrictions, no issues with the throttle moving the mixture lever just go fly.

All of this has been communicated to the Devs ... we now wait for the fix.

What is surprising me is all of the 109 pilots which give the Spitfire a try and then tell us how good it is. How are they coming to this conclusion exactly? because I am baffled......

This is the Spitfire though, try and fight in the Hurricane.

@Longywales, use the 2 stage prop variants for Spitfire and Hurricane, you'll find better performance out of them, not top speed but certainly climb, and they won't overheat unless you treat them badly. 60 degrees oil before you can run though, or 30 degrees if you push the mixture lever full forward with the throttle (presently auto rich, see IvanK's post above)

" (presently auto rich, see IvanK's post above)"

Just Rich not AUTO rich :)
