P47D30/P51D/La7/190A8/190D9/SpitIX and Typh were tested. I found, surprisingly, P47 as only an average diver, P51/SpitIX/Typh were kings of the hill about getting out the dive with little or no trim at all (best of all being the typh by far). 190s needed a lot of trim nose up, D9 more than A series. La7 also needed lot of nose up trim (augering several times). About diving speed, it varied along the dive. SpitIX can stay with 190s at the initial stages, then 190s outdives (slowly) the SpitIX and then there was a "segment" where range kept stable. Once leveled and after some seconds of stalemate, D9 outrunned clearly and suddenly the SpitIX (as if the spit hit a brick wall). A8 and D9 had similar diving but A8 had better elevators to get out the dive, needed less nose up trim. All in all, the winner was the P51D. Curiously, we needed to change the orientation of the take off because P51D kept going uncontrolably to the left even before leaving the ground, crashing over'n over against the control tower or last fighter hangar.

Cant remember the fuel load of that test (probably 50%). It was done from the highest field (NW) of the DA.

>>After the niki chased down my jug in a dead dive<<

Hehe, a Yak chased me down to the deck from 19k while I was in a Jug. He stayed rock solid on my 6 no matter what I did. I was over 400kias and he was still there. He shot me up good, and as I was falling he pulled up and away with ease; he didnt compress or anything.

Well ...

"About diving speed, it varied along the dive. SpitIX can stay with 190s at the initial stages, then 190s outdives (slowly) the SpitIX and then there was a "segment" where range kept stable.

Seems to line up with what JAWS2003 found from British tests ...

"Dive: Comparative dives between the two aircraft have shown that the FW 190 can leave the Spitfire (V) with ease, particularly during the initial stages."

"Dive: The FW 190 is faster than the Spitfire IX in a dive, particularly during the initial stage. This superiority is not as marked as with the Spitfire VB."

So whats the problem ?

Don,

How on earth did you get killed by a Yak at 19K? You should have murdered him up there?

F4U:

He had help

There was a Niki, and of course an La7, and a P38 also. I started out with a lot of alt on them all, and began making passes at them as they climbed up toward me. Each of them, with the exception of the P-38 were able to climb up to me like scalded monkees. I made a pass on the Niki and smoked him, as I turned away the Yak started shooting at me. I pulled a couple of evasives, and the Yak stuck with me like glue, so I dove away. He stayed on my arse all the way down, missing a lot but, getting some hits in. He never deviated from within 350 yds off my 6. At one point I was over 450 kias and he was still there within 325 yds and registering hits. He shot my wing off, and as I fell I looked in my rear view and he simply pulled up and away without much effort, giving no evidence of compression or anything.
I fly the P-47 a lot; I read Gabreski's book about it. Its a good plane but, it sure as hell can't do the things Gabreski wrote about in his book, in AH. So, I fly it anyway cuz I like it.
