So nobody has come up with prop fighter wing bending data during turns so far... Why am I not surprised?
Nobody has come up either with one example of Spitfire out-turning the FW-190A in low speed sustained turns: There is quite a few accounts clearly demonstrating the opposite, with one pilot stating this was a general fact... Quite a discrete 60% advantage let me tell you!
"Il-2 confirms with great satisfaction"
But what about the satisfaction of a real wartime FW-190A-8 Western Front ace?
The only time I ever heard a real WWII German ace directly opining on a simulation forum was through a relative on the Aces High "vehicles forum" around 2005, a Western Front FW-190A ace who unfortunately was not identified by the relative posting his replies to queries, because I suppose there were P-51s being shot down in his accounts, (a rotten deal for making my case at any rate)...
A lot of about the way the posting relative presented his comments made it clear he was in contact with the real deal... He mentionned 3 separate types of aileron chords being available as an offered pilot "option" on the A-8, the widest chord being picked by the ace in question to help "catch" the wingdrop during low-speed turns... He described increasing further the "chord" of the ailerons by adding field-mounted "spacers" on the aileron hinges to increase their effectiveness at "catching" the wing drop, riding the turn on deflected ailerons (He describes precisely relaxing the pull on the stick just as the ailerons are deflected to catch the wing drop)...
He described reversed a tailing P-51D in this manner using just two 360° turns flat on the ground (the P-51 straining very near its stall all the way)...
He described the huge advantage of the broad wood prop, but also the risk of hitting the ground with it on landing (not clear if that was much greater than with the narrow metal prop)...
He described using the FW-190A-8
exclusively as a low-speed turnfighter, reducing the throttle and dropping the flaps before a merge with faster P-51s... He did not care about their greater speed because he could turn to go head-to-head with them if they did not stay with him... Head-to-head was apparently a big advantage for the FW-190A, so the P-51 was presumably just as well off dropping the throttle and turning as well...
The remarkable thing is, I have never heard of such details anywhere else, and yet nothing of the aileron details and other issues has ever been challenged as being false...
I have asked years later of the site owner, surnamed Hitech, to tell me where to find this thread, titled "FW-190A veteran experience" (it went on for about 4 pages the last time I saw it): He actually claimed not to remember it... It is of course deleted from the archives, and he knows nothing about it...
I guess everything the "real deal" had to say just exposed too harshly how current simulations, his and others, were a big pile of claptrap...
But apparently, after all my threads, the Aces high FW-190A got quite a bit better...
