OK, link didn't work. will try nuther way.
home.att.net/~C.C.Jordan/Shilling2.html - Hmmm, nope.
 
Here we go. Check out his definition of maneuverability, interesting.






How did the P-40 compare to the Japanese Zero:

Of all the fighter planes flown against the Japanese, the P-40 was the most under-rated airplane and the Japanese Zero was the most overrated. Contrary to popular belief, the P-40's larger turning radius did not present a problem when understood, and proper tactics were used against the Japanese fighters. Also its lower rate of climb could easily be overcome. The P-40 which was more than 40 mph faster than the zero, could still climb at a speed that the zero was incapable of attaining. Pilots that tried to dogfight lost their lives. Whereas the hit and run tactic with a faster plane was the only way to fight the Hayabusa or Zero.
Erich Hartman, Germany's leading Ace with 352 victories said, "I always avoid the turning combat when ever possible. "In half of my victories," Hartman said, "the pilot was unaware he was under attack until he was being hit." He was also an extremely good marksman. Erich Hartman averaged 70 victories a year. Therefore, why is it so difficult for some Americans to believe that 82 AVG pilots destroyed 297 Japanese in a seven month period?

To put our victories in their proper prospective: If all the AVG pilots had been of Eric Hartman's caliber, we would have destroyed 3,052 airplanes in this 7 month period. Provided there had been enough Japanese airplanes available to shoot down. Now, 296 doesn't seem so terribly outstanding, as a matter of fact somewhat shabby.

The AVG encountered 4 types of Japanese aircraft in their fight over Burma and southeast China. Two were fighters, the Hayabusa we called the I-97 and the Mitsubishi*, an obsolete fixed geared fighter, the I-96. The only Japanese bomber was the I-97, which I think was called the Sally, and an occasional Japanese photo-recon plane.

The P-40s was 50 mph faster than the Hayabusa we called the I-97.
The P-40's top speed was 70 mph faster than the I-96, an early fixed geared Mitsubishi*.
The P-40 was 130 mph faster than the Japanese bomber, and 130 mph faster in a dive than any fighter the Japanese had.
The P-40's pilot protection was in the form of self-sealing fuel tanks. Almost two - inch thick bullet proof armor plate windshields, and 9 mm and 7 mm armor plate protecting the pilot from behind. Also the P-40's armor plate could stop the bullets from any military aircraft the Japanese had in the China - Burma theater.


*Editor's Note: The more common fixed gear fighter encountered over China and Burma was manufactured by Nakajima and designated as the Ki-27. The Mitsubishi fighter, the A5M, did see service in China, but were generally withdrawn by December of 1941 and were pulled from any combat in mid 1942. The Mitsubishi was a Naval fighter (IJN) and the Nakajima served with the Japanese Army Air Force (JAAF). The Ki-27 also offered performance greatly inferior to the Curtiss P-40B/Tomahawk IIA.

The most irritating:

One author, writing for the Smithsonian's Air & Space magazine claims, "The Zero to be the most fabulous fighter to come out of the war." Those making such statements are ill informed. They either never flew the Zero, never fought the Zero as it should have been, and most likely are not pilots, nor aeronautical engineers, so how the hell do they know.
Aviation buffs always come up with the statement that the Zero was more maneuverable than the P-40. Emphatically not true. Flown properly the P-40 was an outstanding fighter, especially in the Chinese theater of war.

Actually the P-40 was more maneuverable than the Zero. Unfortunately, those that claim otherwise do not know the definition of maneuverability as defined by Webster's dictionary.

1. To perform a movement in military or naval tactics in order to secure an advantage.
2. An intended and controlled variation from a straight and level
flight path in the operation of an aircraft.
3. To make a series of changes in direction and position for a specific purpose.
4. Evasive movement or shift of tactics.
5. To manage into or out of a position or condition.
6. To bring about or secure as a result of skillful management.




Interesting comments by Saburo Sakai about the Zero:

In a short but informative interview with Saburo Sakai, Japans leading living Ace, I asked, "Commander, what was the Zero's top speed?" His answer amazed me when he said, "The A6M2 had a top speed of 309 mph. and a maximum allowable dive speed of 350 mph. It became extremely heavy on the controls above 275 mph, and approaching 350 mph, the Zero's controls were so heavy it was impossible to roll. A further comment by Sakai was that the skin on the wings started to wrinkle, causing the pilot great concern, since a number of Zero's had shed their wings in a dive." A captured Zero tested by Americans military, showed its top speed to be 319 mph, this was a later model, the AM6M5, and was tested without guns or ammunition. Therefore Saburo Sakai's statement that the top speed of the A6M2 and A6M3 of 309 mph would seem to be correct.
Saburo Sakai, in an interview made on August 11, 1996, admitted that, after flying the P-51 he had changed his mind and now rated the Zero as number two, where as before he thought it was the best. He said, "the P-51 could do everything the Zero could do and more." My comment to him would have been that it's too bad you never got the opportunity to fly the P-40.

Compare this to the P-40's 355 mph, and he the maximum allowable dive speed of 480 mph, (occasionally our pilots dove as fast as 510 mph) 130 mph faster than the Zero. The P-40's roll rate at 260 mph was 96 degrees per second, three times that of the Zero's mere 35 degrees at the same speed.

Japanese pilots were taught the antiquated importance of Dogfighting, or turning combat as used in WW I. Unfortunately our military pilots were taught the same thing, dogfighting. But the Americans didn't have the equipment with which to be successful. When the Japanese encountered Chennault's hit and run tactics, they were at loss. It wasn't in their book, and they didn't know how to handle the situation.




What was the impact of Japanese propaganda:

"Tokyo Rose" during one of her many English broadcasts, admonishing AVG pilots saying, "Why won't you stay and fight? You're cowards, always running away. Are you afraid of our courageous pilots?" Undoubtedly our hit and run tactics were obviously hurting and the Japanese were too stupid to realize the information she was giving us.
On December 24, 1941, Tokyo Rose announced over the radio that Japan had a Christmas present for the AVG. How utterly stupid, we were ready and waiting. The AVG were confirmed to have shot down 13 fighters and 4 bombers. The British got 6, all confirmed. No losses by AVG or RAF.




What proof is there that the AVG, in the beginning of the war, was the only outfit using proper tactics?:

The Americans were still using the suicidal "Dogfight," or turning combat. When the Lockheed P-38s were first introduced into the Pacific theater in 1943. Saburo Sakai says, "The Zeros were shooting them down in large numbers." Although the Lockheed had a 100 mile per hour speed advantage, this is what happened when the airplane wasn't being used properly. Saburo further states, "When the Americans changed their tactic, the Zero pilots became fearful of the P-38, because they were decimating the Zeros."
As early as September 1941 Chennault was teaching us to hit and run, requiring speed, which was the P-40's forte against the Japanese. When properly used, it outclassed the Japanese Zero in every respect. It took the American Military 2 more years, and the loss of several hundred American pilots, before they stumbled on the secret of successfully fighting the Japanese in the air.




Another misconception given us by revisionist:

According to revisionists, the weave was first used during the battle of Midway, giving credit to Commander Thatch for inventing it, and referred to it as the "Thach Weave."
An article in the Smithsonian magazine, Air & Space, said that Lt. Commander Thach had developed the weave which he said contributed in a large part, "...To the success of the Battle of Midway...." However, Commander Thatch admits he had heard it was used in China. Incidently this weave was used, during our training at Toungoo, and was part of a combat report when the AVG first encounter the Japanese on December 20, 1941.

A controversy developed about the invention of the Thach "Weave" and later it was discovered that Commander never called it a weave but a "Beam Defence," which incidently was not a "Weave" as every one seemed to think.

And this is news to us in what way?

The A6M rolls like crap at speed and we all know this.

I think it flies way too damn fast. I'd LOVE to see the zero lock up totally at 350mph. I'd love to see the wings rip off not far past that (the skin wrinkled, can't last much after that happens)

Ok, having read it I can say that it is a P-40 love fest and is inacurate in somw ways.

The A6M we test flew was an A6M2 that crash landed on the Aluetian islands, not an A6M5 which didn't enter service until mid 1943.

It also doesn't address some of the improvements the A6M series had, such as the 700lbs of weight added in thicker skin on the A6M5 series.

Certainly the P-40 was tougher and handled high speeds much better, but that article is very, very biased.

The IJN measured speed in knots, not miles per hour.  I wonder if Sakai was thinking in knots or mph?

Nobody seemed to mention the part on how they couldn't build a canopy on the P40 that wouldn't cave in above 300 .

You guys need to understand a few things about Erik Shilling. He was a test pilot at Langley in 1939. When he was recruited for the AVG he had more time in more airplanes than anyone else in the organization. Chennault thought Shilling was his "best pilot". So, Erik got most of the difficult assignments, such as flying the AVG's P-40 photo ship, usually alone, deep into Japanese territory. On those missions, Erick shot down several Japanese aircraft, but being unwitnessed, he never even bothered to put in a claim.

After the AVG disbanded in July of 1942, Erik flew C-46 and C-47 transports across the Hump for CNAC. After the war, he flew covert missions in China for the Nationalist government while in the employment of the CIA. He later flew C-119s in support of French effort in Vietnam, again for the CIA. His was the last aircraft to make a resupply drop at Dien Bien Fu. Having absorbed many hits from light MG fire, he nursed the beat up transport to DaNang. After a brief stint flying for Swissair, he was contracted again by the CIA as a pilot for Air America. Erik flew hundreds of sorties into Laos, Cambodia, even into North Vietnam, all in unarmed Pilatus single-engine PC-6 turbo props. He landed and took off from small clearings on the side of mountains, where nothing else could get in.

When Erik retired, he had more than 30,000 hours of flight time. much of it involving incredibly dangerous covert missions.

Yeah, Erik was a bit biased, but he saw the world through the eyes of someone who had been everywhere and done just about everything possible in aviation.

Shilling is one of the great, unsung, American aviators. His fellow Flying Tigers looked at Erik in awe, especially years later at reunions, where they learned about his derring-do in South East Asia. He passed on a few years ago, and I miss him.

I always enjoy the folks who say the person who was there and actually flew the planes doesn't know what he's talking about. :rolleyes:

Wow didn't know that widewing. His comments on maneuverability are quite interesting. Ability to gain an advantage, which higher top speed than ones opponent affords opportunities for. So turn & roll are of course important, but  can be rendered irrelevant by faster plane.

But I'm sure most here already know that.

And where did I say that he didn't know what he was talking about in regards to the P-40?

Oh, that's right, I didn't.

I merely said it wasn't accurate in regards to everything said about the A6M, which he did not fly.

I have never seen that info from Sakai before, so it is suspect given his take on the P-51 and P-47.

I've got a copy of the interview with Sakai somewhere here, I'll try to dig it up.  A link to it was posted here on the BBS several months back.  He did indeed make the statement about the P-51.



Here ya go.  Note the section titled "On the Zero".

Yes, I know Sakai's comment about the P-51, and I agree with it.

I wasn't refering to Sakai though.  :p

I'd like to see where Sakai said the A6M had a top speed of 309mph.  I have not seen that bit of data.

Saburo Sakai is one of the WWII aces I most respect.

Ah, sorry.  Misunderstood the last line of your post.  Cant help you on the speed.  Only quotes I recall from Sakai praising the zero were about the range.  He always said it was more maneuverable than the American planes, and that it was a great all around fighter, but mostly it was because of the range.  He even said in that interview that the I-96 (A5M) handily outperformed the zero one on one, but that it didnt have the range to be a great fighter.  

Warbird Resource Group lists the A6M2 as having a maximum speed of 316 mph (doesnt list cruise speed).  The A6M5c is listed as having a max speed of 354 mph.  Initial climb for the A6M2 is listed as 4500 ft/min and the A6M5c at 3150 ft/min.  

No stats are listed for the A5M (for comparison sake), but data I read from russian testing of a captured plane in 1938 showed (no speeds) 4.3 minutes to climb to 3000m, 200m to get off the ground.  They admitted though that the engine was built out of parts from several others, they had to manufacture a propeller, and they had cooling problems all during the tests.
