I believe I have to jump in here.
RA, what's your source? I have one of the few, and probarly the best specialized TA152 book on the market, trying to see if I can find anything about the TA152 H being taken out of action but for what I remember now, the last time I read it I found no such thing. There were however, as you say, only 2 TA152C's that survived the war, only two reached service at all as grunherzed said, although he could difinatly said it in a more mature and intelligent way...

Wotan, the AH the charts seem to be wrong (no matter how freaking weird that sounds). Check my chart bellow, it's the old chart that shows speed all the way up to 50k, and read my tests bellow, could these speeds have improved because of 25% fuel load?
Now, check speed at 41.000 feet, that was where the TA152H-1 had its top speed, using GM1 power boost, water Methanol was held in the wings.
The AH speed charts show exactly 450 Mph. I did a test in AH, using 25% fuel only, I dove from 50k to 41k, used WEP for 10 minutes and then checked speed in the new film viewer, speed that was reached was 460mph. Not what the AH charts say, faster, which is GOOD.
What is more important is that its max speed is reached nearly 10k below the alt of what it was in real life, and great disadvantage in high alt performance.
Check speed at 31k, shows about 460, which is very right from my test where I, after 10 minutes WEP and dive from 40k had a speed of 461mph.
Weird huh? Speed is the same at 41k aswell as 31k...
The TA152 is lovely in AH.
At low alt it's still good and probarly as it should be, hold E great, good guns, fairly good speed and very good acceleration. Turns well too. It can challange most planes, the problem is the perk icon, as with all planes, brings out the worst of people

I have charts with most other TA152's then the H-1, inlcuding DB equiped ones (belive me, you non LW flying people do NOT want a DB equiped TA in AH

).
If I only had somewhere to upload images too I could post some charts.
I will make a separate thread about the TA152, post engines and some stuff and maybe we can get a real "is it actually wrong?" discussion going
I'll also post Kurt Tanks own words about the "Attack of the P51's" when he had just taken off, check under General Discussion soon.
Btw, anyone know a place where I can upload images and films?
As soon as I have some kind of webspace I can get started with charts...
