Very Selective. My personal favourite is where he states that because a Hurricane has a smaller turn radius than an early Spitfire. It follows that as a result, this apparently proves:-Unfortunately you are very selective in what you post to support your agenda.
Quote: "So here is a quote from Hurricane pilot John Weir (John Weir link won't work for some reason):
I also thought the Spitfire Mk V sustaining turns equally well as the Mk IX at 30 000 ft. (or 15 000 ft.), despite a drastically slower climb rate, would also be a clue as to the slight "perils" of maths...
Gaston
The pilot of the Spitfire VC found it difficult to maintain a steep turn without losing height, whereas the pilot of the Spitfire IX found that he had a large reserve of power which enabled him to maintain height without trouble.
Which is in direct contradiction to the theory that de-rating (less power) is an asset to sustained turn.
The Spitfire illustrates this point very well. The tactical trial reports (that we all have access to) show quite clearly that each successive Mk of Spitfire was heavier (higher wing loading ), but that manueverability stayed pretty much the same (albeit with a different 'fee'l as reported by pilots). We have the Mk I, II, V, and IX, with the same airframe, but increasingly powerful engines, and similar turn performance. Mk VIII and Mk XIV with same airframe, and same manueverability. Thats an increase from 6000 lbs to 8400 lbs from Mk I to Mk XIV and no appreciable loss in turn performance. And that would be attributed to horsepower increasing from 1030 to 2035.
Jabberwocky? Could you provide a link to the Soviet turn tests?

Hard to dispute gun camera footage Gaston.
Doyle noted bullet damage in the cockpit area and his gun camera footage showed that it was Oesau's Green 13.
The Germans had a habit of saying they were shot down by Spitfires instead of an lesser a/c. The P-51 was considered a better a/c than the P-38 by the Germans.

I would suggest you read 'The Long Reach'.
In it, P-47 pilots tell of doing yo-yo turns to stay with 109s in a turn. It also says in a horizontal turn engagement not to turn more than a half turn with the EA.
Unfortunately you are very selective in what you post to support your agenda.
Gaston, you keep claiming that the Fw-190 has a tighter sustained turn radius than any other fighter in the West.
Yet, the RAF tests and the Soviet test both say that it had a larger sustained turn radius than just about any fighter of the war, with the possible exception of the P-47D. Even the Typhoon and Tempest in RAF tests are noted as having better turning circles than the FW 190.
RAF testing with a clipped wing Spitfire Mk V showed that the aircraft had a 40% smaller sustained turn radius than the FW 190A4 at 20,000 ft.
Soviet testing of a LF MK IX (again with clipped wings) shows a 45% smaller sustained turn radius than a FW 190 A5, this time at 1000 m (3,300 ft).
Soviet turn time testing shows that the FW-190 did a sustained circle in 22-23 seconds at 1000 m, worse than any other fighter they test, bar the P-47D and the Mustang.
Testing by four air forces: RAF, USN, Luftwaffe and VVS all indicate that the FW 190 is not a turn fighter.
What is it that you believe makes the FW 190 a good low speed turn fighter?
Is it the very high stall speed (125-130 mph)?
The very high wing loading?
The tendency to go into snap stalls at low speed?
The tendency to reverse aileron control at low speed?
The RAF tactical trails suggest nothing of the sort, and to state otherwise is disingenuous in the extreme.
The Mk IX vs Mk V trails state:
"At 30,000 feet there is still little to choose between the two aircraft in manoeurvrability, but the superiority in speed and climb of the Spitfire IX becomes outstanding. The pilot of the Spitfire VC found it difficult to maintain a steep turn without losing height, whereas the pilot of the Spitfire IX found that he had a large reserve of power which enabled him to maintain height without trouble. The all-round performance of the Spitfire IX at 30,000 feet is most impressive. "
Let me see: Gun camera footage is in COLOR now, and the actual wingman German pilot cannot tell the difference between his leader being chased by a P-38 and chased by a P-51 Mustang...
It is true the two can be easily confused...
Anyway if the footage is clear, then did you know they stupidly put the P-38's gun camera in the nose near the guns, which when firing obscured everything by vibration and smoke? If when firing the image is clear, then you'll know the footage comes from a P-51...
The guncam footage must be online somewhere...
Quote from AFDU trial on P47-C (yeah I know it's not a D)And you would realize too that the P-47D Razorback almost certainly out-turns in sustained turns the Spitfire, since the P-47 can match sometimes the FW-190A, which the Spitfire, it is now clear from the Hurricane pilot quote, had no hopes of doing...
25. Manoeuvrability – The good aileron control gives the P-47 an excellent rate of roll even at high speeds, and during mock combats it was considered to roll as well as, if not better than the Spitfire at about 30,000 feet. At lower altitudes there is nothing to choose between them. The rate of turn of the Spitfire is naturally superior to the heavier P-47 and in turning circles it was found that after four turns the Spitfire could get on the P-47's tail and remain there with a chance of shooting with correct deflection....
Turning Circle
18. The turning circles of both aircraft are identical. The Spitfire XIV appears to turn slightly better to port than it does to starbord. The warning of an approaching high speed stall is less pronounced in the case of the Spitfire Mk XIV.
41. Spitfire XIV can easily turn inside the FW 190, though in the case of a right-hand turn, this difference is not so quite pronounced.
I did not say a TIGHTER turn, I said a FASTER turn rate...
As for the Soviet turn times: These are not comparative tests at all... They were not done on the same day, which can lead to 10-20% discrepancies in numbers according to the humidity...
That comment is simply not true. All test results analyzed by competent engineers first normalize the data to STP. The Soviets were extremely competent engineers.
These are tests done for wind tunnel evaluation procedures, they were intended to calibrate wind tunnel test results; They have nothing to do with actual test comparisons and were never intended to be used as such by anyone...
Wind tunnel tests are about predicting behavior for level flight and developing Drag and Lift and Moment data. Flight tests are all about determining what 'reality' brings to the table.
This information on the background of the TsAGI tests was relayed by another poster on this site (I will link his quote). There are other issues of aircraft unfamiliarity as well, plaguing all these formal tests, and barring seeing the original documents, I saw one Russian-language site quoting the TsAGI turns times for the FW-190A-4 as 19-23 seconds (?), one second below the Me-109G-2 or F for the 19 seconds side of the quote...
Like all formal tests, TsAGI tests are more misleading than the near-perfectly coherent picture of a large number of combat reports and front-line observations...
Pilot skill and a/c condition are the plague of flight test results for manuevering..
Gaston
P.S Still waiting for those super-out-turning Me-109G combat reports... I mean by that, the Me-109G out-turning ANYTHING (Karhila's downthrottling to 160 MPH quote is the only one I am aware of: I eagerly want to find more...)
Oh, and are you really sure Karhila's 160 MPH "optimal" sustained turning speed can be at full power? Tsk-Tsk...

If I can add to Claidemore's posting these test results were supported by the combat reports I posted on Posting 96.
However to deal with the Fw 190 being outturned the following examples were in the link I did give you.
PO J Stewart 30th July 1942
I stall turned to attack the rear two Fw190, They broke and turned with me but I could easily out turn them and got several bursts at the rear one.
S/Ldr Watkins 19th August 1942
A FW 190 dived down to my height and swept around behind me, I easily turned inside the enemy aircraft and fired a short burst at 45 degree deflection
Flt Lt Manak 5th September 1942
One of them got onto my tail I avoided him by a left hand climbing turn
S/Ldr T Gaze 11th October 1942
Whilst the left one turned, I easily out turned him and fired a long burst.
So we have the test reports being supported by pilots combat reports that the Spitfire can easily turn inside a Fw190.
Against this we have a report from a Hurricane Pilot. Now lets think about his for a moment.
a) Did this pilot ever fly a Spitfire in combat? I don't know but the probability is that he didn't. Most Hurricane Squadrons were either posted overseas or converted to Typhoons. His comment makes sense if he was flying Typhoons against Fw 190, as there was little in it so the tactical situation and skill of the pilots involved would have a major influence on the result.
b) If he was only a Hurricane Pilot did he fly combat against Fw 190? Possibly as a Hurrie Bomber which adds another factor to the debate. The RAF knew that the Spit V was clearly outclassed by the Fw 190 and would not knowingly send Hurricane fighters against the Fw 190, as their chances of success were very slim, at best.
