Weird, seems like their server is down. Thanks

Mmh maybe in the Structural repair Instructions you find what you are searching for, page 80: Avialogs: Aviation Library - AN 01-60JF-3 Structural repair Instructions for P-51H Airplane It is a 1945 manual so it is not updated on sizes but it is free. Also outdated from 1945 but free the...

Also, you might have a subscription to aircorpslibrary (9$ a month), they have an infinite amount of sources and original drawings as you might already know. They have the latest erection and maintenance instructions I could find, 1948 and it includes updated dimensions and stations...

Hi, the tail was changed for the production like @mjfur did show in pictures. That is why some manuals/sources list different tail sizes. You can check the NACA document explaining the changes: Measurements of the Lateral and Directional Stability and Control Characteristics of a P-51H Airplane...

Lmao what are you talking about. The hornet and the sea fury both have good performance at mid to high alt. USN developed the F4U-5 and the F8F-2 which are high alt beasts.

Yes, the AU-1 (F4U-6)uses the same engine as F8F-1 and F7F-3. Quite a good engine at low alttitude but lacks mid-high alt performance at high power settings. The french requested an AU-1 version with high alt performance and the R-2800-18W was back on the F4U-7. So high alt performance is...

No, check the link. 100/130 + water at 60'' Also btw F2G-1 655kph is at 100/130 Military Power at 52'' . So probably the fastest in power setting to speed.

F4U-4 is 626kph clean: Wayback Machine

Water Injection 60'' or even 70'' can be used very safely in intermitent 5 minutes periods until water is out (around 12 minutes of use). Military 55'' 2100-1880-1700 can be used in intermitent 5-15 minutes periods, unlimited. Normal 47-49'' 1700-1630-1550 can be used in unlimited periods.

I have to go with the R-2800-18W, very powerful yet compact and in combat in 1945 in the F4U-4:

Posted it here before:

Just like many engines. Every R-2800C with just 100/130 can use 70'' with water injection.

https://www.aahs-online.org/images/Navy_SAC/F4U-5.pdf I estimate clean performance would be about 25 knots faster. So about 640kph at SL and 780kph at 31000 feet!
