??? - I'm trying not to laugh
My pedals :)

Totally serious... load up IL-2 Compare from 4.07 and 4.11 and check.

FW190A-5 in 4.07:

Best turn speed: 370kph
Turn time at best turn speed: 24+ seconds

Turn time at 280kph: 33 seconds
Turn time at 420kph: 25+ seconds

In 4.11:

Best turn speed: 310kph
Turn time at best turn speed: 23 seconds

Turn time at 280kph: 26+ seconds
Turn time at 420kph: 27+ seconds

So you can see the turn parameters are different and largely better. There is a slightly slower turn rate at the higher speeds but it's a 2 second difference while at lower speeds there is a 7 second advantage. Overall the chart shows a wider spread in 4.11 meaning there is a better overall turn rate for the FW190 across the speed range than there was previously.

It also works seat of the pants... which is why I checked in the first place.

I'm not sure if he's saying the FW190 doesn't turn well enough or if it turns too well.

He is saying that it is turning better than it used to prior to the FM overhaul. And he is right.

Are you seriously saying that there is no evidence that the Spit turns better than the Fw190?

...at low speed, just above the stall. This is where Gaston is making his point.

Everyone is going 'No ways, it can out turn them as all the flight comparison tests have been done' - I'm also yet to see an official WW2 low speed turning comparison. That Russian report might be the closest that we'll ever get..
:)

BTW .. online the one time I had a Spit, probably a IX, on my tail when I slowed down to full flaps and 50-100ft above the ground. I went into a gentle right bank and he followed, I then threw it into a full hard RH turn at full throttle and right rudder. The Spit couldn't follow - maybe the pilot or maybe the FMs might be correct.

The Spitfire stall speed is lower and therefore it turns better at low speed. In fact it can still turn at speeds at which the Fw 190 can't even fly straight any more.

my 2 cents
About maneuverability and turn rate ..

PLEASE Do not think about "HISTORICAL DATA" and turn rate and dont think about the mathematics and measures..
Think about the pilot!
and think about what you do not know

In the stick P-51D, measures 48 lbs in a 3g pull. Up to 86 Lbs at
5g's.
The P-47D, OTOH, requires just 16 lbs at 3g and 27 lbs at 5g's.
The testers state that the Mustang was a true "two hander".


The turn rate is less important for a dogfight..

Look at other things ..

You have a good point.. it probably made the difference which is not mentioned in combat reports

Radial-vs-Inline which can have a marked effect on turning ability.. ignored also (and mentioned in some report which I forget) is the FW190 ability to hang by it's prop... which looks like a Radial characteristic.

:)

Another example I can come up with on the radial vs. inline comparo is the P36 vs. P40.

The Army Air Corps P36 C had 1200bhp with 100 act fuel, whereas the P40s that replaced it only had 1000bhp.

The P 40 was faster in level flight, but, the P 36 could out turn it (from pilot accounts), and the P 36 was significantly faster in the climb. (3 to 4 minutes faster to 20,000ft. depending on model of P 40).
