Getting back to the 190 vs Spit/109 in turning, there are anecdotes that the 190's were more agressive and would enter turnfights. I have found one of them first hand, and am still exploring it (hoping to get my hands and eyes on the log book).
Anyway, the encounter took place at medium altitude, which favours the 190's power-curve very much.
It would have been an early type - A5 possibly.
There is no data at the available E at the merge, but I find it likely that the 190 had more.
The Spitfire pilot did know that much of the properties of the 190, only that they were "told to be faster, more aggressive and more maneuverable" than the 109's.
He tried to shake the 190 in a turn and was unable to (unlike the 109). So, instead of carrying on untill stalling at SL, he did a flick-trick, - some kind of a high speed stall where he was basically changing directions under the nose of the 190, then diving away in the opposite direction. The 190 lost him completely.
Had he known the true properties of the 190, he might have carried on turning :D
Anyway, high speed turning, 190A vs SpitV (And those 190A's over the channel in 1941/42 were not the "heavy" ones as later) is something the 190 could risk better than a 109. If things started to reverse, they could roll out and dive away, and be done with it much faster than a 109.
It was very interesting to carry out the flight trials at Rechlin with the Spitfire and the Hurricane. Both types are very simple to fly compared to our aircraft, and childishly easy to take-off and land. (Werner Mölders)

Gaston, you seem to place a lot of weight on testing and combat reports, but it's clear you haven't read VVS evaluations of the Bf 109 and Fw 190.  Russian pilots held the Bf 109 in higher esteem than the Fw 190 and confidently claimed that it was the better dogfighter of the two.

Not long ago, a rebuilt 109G-10 was compared to a P-51D in a flying magazine (I forget which one), and the author was scandalized to report that the 109G-10 out-turned the P-51D. :P

I have seen a similar interview.
I wonder about the weights included though. Every pound you save in the 109 (armour and so) counts a lot more....
And did the P51 use a notch of flaps?

Did you see Gaston's hilarious twisting of language and commons sense where he took the quote from a German pilot "The 190 was a broadsword, the 109 was a rapier" and twisted it around somewhere in the dank crevices of his mind to mean that since a "broadsword" is swung in circles (he asssumes), and a rapier is used in linear thrusts, that must mean the 190 was the turner and the 109 was the bnz'er...completely ignoring the obvious original intent and common usage of that "broadsword vs. rapier" comparison of course, but entertaining in its very dementia.

Well, since the East Euro tradition is very fond of angular thrusts and false edge cuts with their sabers, OBVIOUSLY sabers must represent thrust vectoring aircraft...

Obviously, it would be the collision model.  Saber's are designed to hit thing.  They don't cause any damage to your opponent unless you can hit him with it.

Taken a step further, rapiers and broadswords are designed for the same things.  Comparing the 109 and 190 to those leads me to believe someone thought the obvious outcome of fighting with these planes would lead to an inevitable ram?  And that no damage to the enemy would occur unless you could slam your weapon into him?

Correct me if I'm wrong but doesn't Gaston claim to be a game developer that has developed a table top flying game supposedly using accurate flight model data?  If that's the case, I don't think I'd want to buy a game he's developed.

How's that one?
Anyway, sabre vs broadsword puts the sabre as the nimbler one and the Broadsword doing more damage.
And here...couldn't resist:D

Why is the UC dropping on the 190 when it is taking hits? I have an anecdote of one leg dropping in such a case.

    That Rechlin assesment is but one of hundreds of references of the FW-190A out-turning the Me-109G... Did you notice the Russian combat evaluation and the British RAE also said the same thing? Rechlin DID say much later that a MW-50 109G out-turns an unspecified FW-190A...

    Note the video's Rechlin quote says "The FW-190 out-turns and out-rolls the Me-109 at ANY speed", which I think is a better high-speed turn performance than later FW-190As are capable when the engine was moved forward 6 inches, changing the center of gravity significantly: Note how terrible is the turn performance above 250 MPH for this 6" longer-nosed A-5:

    
     http://img105.imageshack.us/img105/3950/pag20pl.jpg

    Note also how this evaluation emphasises the FW-190A's low-speed turning, just like the Russian combat evaluation "The FW-190 will inevitably offer turning combat at a minimum speed" etc...:


  
     http://www.ww2f.com/russia-war/21828-russian-combat-experiences-fw-190-a.html


    Note also that unlike RAE and US Navy evaluations, that absurdly emphasize the FW-190A's "interceptor" or "vertical fighting" nature (despite a poor climb rate and terrible, speed-wasting "sinking" dive pull-out!), these above two evaluations were done by front-line FIGHTER pilots, including the P-47 comparison done in Italy by front-line FIGHTER pilots, NOT test pilots, and THEIR opinion offers a stark contrast to TEST pilot opinions: Which one would you rather pick? There is NO reconciling these two views... Guess whose side Johnny Johnson falls on, with the hindsight of the whole war being over? ("vertical turn" here is actually a "wings vertical turn" in the era's pilot lingo; please don't go down that path, ok?):

    -The pilot was Gunther Rall, who also said the Me-109F could barely out-turn the FW-190A, and usually didn't, at 900 lbs less than a Gustav...

      I am told he actually said, actual quote: "The Me-109 was a floret, the FW-190 was a sabre", which inevitably leads to a VERY interesting question by Ack-Ack, quote:

     "What part of a plane's flight model would a Saber represent?"

     Now THAT's an interesting question. Hint: The sabre always has a blade shaped in a curve.... It can stab, but is in priority designed for hacking in a curve in confined spaces, or from a horse, the curve facilitating both the draw and the pulling, slicing motion to deepen the cut after the CURVING stroke has bit flesh... Hmmmm... Now what could THAT possibly mean compared to a floret?

     The floret, on the other hand, has a straight blade with nearly or absolutely no edge, intended for straight strokes only... This is a floret:

    
  

      http://upload.wikimedia.org/wikipedia/commons/thumb/f/f8/Foil-2004-A.jpg/505px-Foil-2004-A.jpg

     This is a sabre:

    
  
     http://upload.wikimedia.org/wikipedia/commons/thumb/f/f2/Sabre_mg_7029.jpg/600px-

     Some had less curve, but were still clearly hacking weapons more than straight-line thrusting:

     Another Saber: http://england.prm.ox.ac.uk/englishness-british-cavalry-sabre.html

     I tell you, denial is truly indestructible...

     Quote, Anaxogoras: "Gaston, you seem to place a lot of weight on testing and combat reports, but it's clear you haven't read VVS evaluations of the Bf 109 and Fw 190.  Russian pilots held the Bf 109 in higher esteem than the Fw 190 and confidently claimed that it was the better dogfighter of the two.

Not long ago, a rebuilt 109G-10 was compared to a P-51D in a flying magazine (I forget which one), and the author was scandalized to report that the 109G-10 out-turned the P-51D."

    
     -As far as the Me-109G-10 out-turning the P-51D, I actually think this is could be true at the most common medium speeds, even maybe for the G-6, since same-side turning combat with the P-51D can last an incredible 15 minutes in combat reports, which indicates they are very close, except for the Me-109G-6's speed-bleeding in level turns that really needs a downward spiral or MW-50 to even things up, despite a likely tighter radius that could lead some pilots to conclude it "out-turns" the P-51D easily.

      Above 300 or 350 MPH I think the P-51D will display an increasing superiority with speed, inevitably decelerating into the Me-109G's better speeds, but below 200 MPH the P-51 can also downthrottle and increase prop pitch with flaps down, what I call the low-speed "trick":

    
  
    
     http://www.spitfireperformance.com/mustang/combat-reports/339-hanseman-24may44.jpg

    
     Barring that, they can be described as very close depending on pilot knowledge, and both are inferior at low speed to the FW-190A, which is itself not far behind the Spitfire (see Johnny Johnson Spitfire link above).

     As far as Russian opinion, also see link above...

     Maybe what you are refering to as "Russian opinion" are a large series of 360° turn times, 18 sec., 21 sec., etc, that cover a wild variety of aircrafts, with many minute variations among an intricate number of variants... To my eyes, there are strong clues that these are not actual data from actual flight tests, but some calculated figures that were trusted by test pilots and put in a report somewhere...

     Remember what I said about test pilots versus FIGHTER pilots?. For hundreds of Russian FIGHTER pilots opinions, condensed over months of actual combat with actual German FIGHTER pilots, see the "Russian experience" link above...

     All these Russian ultra "precise" "turn times" are likely calculated, which was often not mentionned at the time, and the best indication is the sheer NUMBER of test aircrafts that would have to be involved on the same day for these tests to be valid (temperature, humidity etc... can cause HUGE turn performance variations, but probably affected all aircrafts roughly the same...). Just imagine: Three or four variants of Spitfires? Three or four variants of Me-109s and FW-190s? Have you ever seen a REAL flight test that looked like that? Of course not: You don't even have the time in a day to test all that... Plus the data I am told matches calculated data very consistently, which is another huge red flag...

     The total absence of directly linked pilot comments is also very telling... Turn rate has many aspects that require more than just ONE number: Control feel, response, speeds and weight anyone?

     Finally, I have already asked in the past about these turn-time tests some simple questions, like, on what DATE they were done, and what serial # of aircrafts were involved(???)... I'd be REALLY curious to see the answers to that... Don't hold your breath... I haven't so far.

     If no answer comes up, then you'll have your answer: Such tests would be the most exhaustive turn-rate tests of WWII, and not a single DATE can be put to them? What does this suggest?

     It would be nice to know the speed ranges and the use of flaps too, while we're at it...

     Quote, Anaxogoras: " Russian pilots held the Bf 109 in higher esteem than the Fw 190 and confidently claimed that it was the better dogfighter of the two."

     -They did hold it in high esteeem, because it could perform at higher altitudes than their aircraft, and it could use dive and zoom tactics much better than the FW-190A. Up to the Me-109F, it could also compete in turns, but listen to Gunther rall's complaints when the Me-109G came along... "The weight went too far" he said... Still, the Me-109G had a superb climb rate and could therefore make excellent use of the vertical plane ("floret" anyone?), unlike the FW-190A, as the "Russian Experience" evaluation points out: "The FW-190 does not like to do vertical maneuvers"- "Keep speeds as high as possible against the FW-190"- "pulling OUT[of a 45° dive], it will fall an extra 200 m."- "The FW-190 will inevitably offer turning combat at a minimum speed (sabre, anyone?)" etc ad nauseam...

     In the Western Front, the Me-109G-6 no longer had the higher altitude, or the better zoom, or the better dive speed, or the better tail-heavy trim pull-out (not by much at least), or even the better steady climb rate against a 72" P-51, or any kind vertical maneuver advantage. This is why a Luftwaffe officer said: "All those aces that came to me from the Eastern Front got shot down on the Western front."

     By late 1944, 70% of Luftwaffe Western Front fighter strenght was FW-190A-equipped... Not so the Eastern Front I would guess.

"The engine installation makes the ‘109’ types look very different.  Because of this difference in appearance, the Buchon has always been compared against the Daimler-Benz engined aircraft, notably the G model ‘109’, and the data below give a good comparison of the two aircraft."

Why did YOU ignore that I provided a link where the differences were explained?   :rolleyes:
