Level @ 20k - Zoom Climb
Bf 109 G10 265 mph - to 25k
FW 190 A8 250 mph - to 24k
P 51 D 270 mph - to 25k
Spit 9e 250 mph - to 24k
La 7 3B20 285 mph - to 25k+

they all seemed to be relatively close to data I could find on the internet (wiki) except the La7 which seemed to be significantly too high.

**I just recently found this site with real test data http://www.wwiiaircraftperformance.org/
*** here is a site if you are interested in how to calculate TAS and other stuff http://www.scenery.org/faq_aviation.htm

Curious which La-7 data you were using for testing? I've only found one source recently that gives any information of interest at all.

Right her: http://www.desertstar.co.uk/warbirds...formLa5La7.pdf

There are a couple of different La-7s tested too...and their performance varies drastically.
