I guess it's quite possible that radiator failure on a 109 isn't as devestating as it would be in a Spit/Hurri?

If that's historically correct, then I guess it's okay. Just a little more uphill for us Red to climb

Redundant systems, the 109s had a system for shutting pressure to a damaged radiator, and a single rad was enough to cool it somewhat. Although it shouldn't last forever at high output, it would be a far longer lasting than the single rad being damaged in the RAF planes.

I believe this was introduced only with the latter batches of 109F; the Emil did not have them.

On the other hand, the Emil did have an 8mm armor plate right behind the fuel tank, which would render the fuel tank bulletproof from .303 hits from directly behind (it was possible though to hit the fuel tank directly if fired from an angle and bypass the armor plate).

"We've performed a tremendous amount of work testing and improving flight models in the game, as well as improving various aircraft engines"

Wonder what "improving aircraft engines" means? Just improving engine power at various altitudes could have a big impact on performance - such as the ability to maintain a certain turn rate. Let's wait and see.

I'd really like to know who "Sean" is - the guy who supplied the testing data. Anyone any ideas? He might be able to tell us the source of the data and give us some confidence in the FM tweaks.

Could be Sean Trestrail mentioned in this old post?:

Yes its me. The Source data comes from direct copies of Spitfire,Hurricane (and RAF test data on 109and 110) copied from original files after countless days spent in the UK national archives. The files were copied by photographing each page. All the data was then provided to the team as is. However these are not the sole references used but add to the "data bank"

Here is sample of in game climb performance overlayed over original Source Data from the Archives.

Wow, thanks Ivan, you're a star. This is just the thing the community needs.

So climb rates look pretty accurate to me (except the 109) until you get to higher levels. Personally, as the devs are being quite open about the high altitude performance drop off, I'm happy to wait for the improvements in the sequel. It's just great to know:

1. they are using official data
2. they are aware of the current limitations
3. they are working hard to correct and improve things

Thanks again for coming forward Ivan, a little info can go a long way.

Cheers

I wonder what data what used for speed? Expecially for 109 E (beacause now is too slow) . And if +12 lbs emergency boost (100 Octan fuel) was modeled in British fighters?

all i can say is that the damage model of the spits and hurris has the same problems like the one of the 109s.
i have shot several fuel tanks of hurris, and they keep flying as well, just like the 109s do.
i have yet to blow up a fuel tank of a spit(does it even have one?)
i have shot radiators of spits and they sometimes keep flying and fighting for a pretty long time until they finally get apparent problems....
